astronomer; Catholic priest; seismologist

Died : 14 October 1982, Rome, Italy

Daniel Joseph Kelly O’Connell (1896-1982), Jesuit priest, astronomer and seismologist, was born on 25 July 1896 at Rugby, England, one of four children of Irish-born Daniel O’Connell (d.1905), Inland Revenue officer, and his English wife Rosa Susannah Helena, née Kelly (d.1907). Soon after the death of his mother, Daniel was sent to Clongowes Wood College, Dublin. At 17 he joined the Society of Jesus at Tullabeg and in 1915 entered his juniorate at Rathfarnham Castle. He majored in experimental physics and mathematics at University College, Dublin (B.Sc., 1919; M.Sc., 1920; D.Sc., 1949, National University of Ireland). Subsequently he studied philosophy at St Ignatius’ College, Valkenburg, the Netherlands, where he began watching variable stars, especially eclipsing binaries that were to become the main focus of his astronomical research.

O’Connell planned to attend the University of Cambridge but, due to a lung condition, he was advised to leave Britain. In 1922 he arrived at St Ignatius’ College, Riverview, Sydney; he did his regency, taught physics and the next year became assistant-director at the college’s observatory. He returned to Ireland in 1926 to complete his theological studies at Milltown Park, Dublin. Ordained on 31 July 1928, he undertook his tertianship at St Bueno’s College, Wales. In 1931 he travelled to Cambridge, Massachusetts, United States of America, to study at the Harvard College Observatory with Harlow Shapley.

Back at Riverview Observatory in 1933, O’Connell became director in 1938. At the observatory his research included seismology and the measurement of time with various kinds of clocks, as well as astronomy in the field of variable stars using the newly developed technique of photographic photometry. In 1935 he was elected a fellow of the Royal Astronomical Society and a member of the Royal Society of New South Wales; he served on the RSNSW council (1946-49) and as vice-president (1950-52), and became an honorary member in 1953. He was chairman from 1946 of the board of visitors of Sydney Observatory. One of the friendships he established while in Australia was with (Sir) Richard Woolley, director of Mount Stromlo Observatory. O’Connell presented radio talks, including a series of three titled ‘According to Hoyle’ on the Australian Broadcasting Commission station 2BL-2NC in March and April 1952.

That year O’Connell was called to Rome as director of the Vatican Observatory. On 26 July he left Australia, arriving in time for the Rome meeting of the International Astronomical Union. He continued his work on eclipsing binary stars, again using photoelectric photometry. A leading expert in the field, he was president (1955-61) of the commission on photometric double stars of the IAU. He published The Green Flash and Other Low Sun Phenomena (1958), which included colour photographs proving that the phenomenon, sometimes seen at sunrise or sunset, was real and not subjective.

At the Vatican Observatory O’Connell built up the staff and installed a 60/90-cm Schmidt telescope that became the observatory’s largest instrument. As objective prisms were available, the telescope was used for spectroscopy. With leading scientists he organised two study weeks—one on stellar populations in 1957 and another on nuclei of galaxies in 1970—and published the proceedings. He had personal friendships with three popes, especially Pope Pius XII. In 1970 he retired from his observatory post but continued as president (1968-72) of the Pontifical Academy of Sciences.

O’Connell died on 14 October 1982 at the headquarters of the Society of Jesus in Rome. He is remembered mainly for his work on eclipsing binary stars and the ‘O’Connell effect’ that relates to the rotation of the major axis of the elliptical orbit of a double star.

Daniel O'Connell's secondary education was at Clongowes College, Dublin. He entered the Society at Tullabeg, Ireland, 8 September 1913, and juniorate followed at Rathfarnham, 1915-20. He received his diploma in experimental physics and a Master of Science in mathematics at the University of Dublin, and later a doctorate in science from the Irish National University At this time he came under the influence of William O'Leary, the Irish Jesuit astronomer and seismologist, who at that time was director of Rathfarnham Castle Observatory in Dublin.
O’Connell then studied philosophy at Valkenburg, 1920-22, and did further tertiary studies in science, gaining first class honours in most subjects. It was while in Holland that he also pursued spare time astronomical studies under world famous Jesuit scientists like Michael Esch, expert on variable stars, Xavier Kugler, world authority on Assyriology and Babylonian astronomy; and Theodor Wulf world ranking physicist.
Regency followed as assistant director of the Riverview observatory, 1922-26, as well as physics master and second division prefect. At this time he undertook to advance the local study of solar radiation.
He went to theology at Milltown Park, Dublin 1926-29, and to tertianship at St Beuno's, Wales.
O'Connell studied from 1931-33 at Harvard College Observatory, Cambridge, Massachusetts, and was subsequently to have studied with the famous Sir Arthur Eddington. However, because of a lung condition, he returned to Australia, and then worked first as assistant director and later as director of the Riverview observatory 1933-52. Then he was appointed moderator of the Vatican Observatory at Castel Gandolfo, Rome, 1953-70. He lived in the Jesuit Curia, Rome, and from 1974 was due president emeritus of the Pontifical Academy of Sciences.
During the years that O'Connell was at Harvard, the observatory was at the centre of major developments in astronomical research and especially those that were to lead within
the next few decades to the notion of the expanding universe of galaxies. He was thus associated with such eminent astronomers as Harlow Shapley, Cecilia Payne Gaposhkin, and others. His principal occupation at Harvard, and a pursuit which continued for the rest of his life, was the study of variable stars; but he also became known as a keen card player, especially bridge.
On his way back to Australia he visited Mount Wilson and Lick observatories in California, and then went to Japan, China, Java and the Philippines, where he visited leading observatories and advanced his practical studies.
While at the Riverview Observatory, working under William O'Leary, and in addition to his study of variable stars, he developed a keen interest in seismology and in the measurement of time with various types of clocks. This latter focus led him into a lifelong interest in the calendar and calendar reform, a study that served him well in later decades since he was asked to advise popes on both calendar reform and the cycle of ecclesiastical feasts.
In 1935 he initiated the “Riverview Observatory Publications” which enjoyed international reputation. Later, he founded the “Reprint Series” and the “Geophysical Papers” that became also well known. In the field of astronomy, O'Connell worked on eclipsing stars and Cepheid variables For the latter he used photo-electric equipment. About 15 ,000 plates on variable stars were on file at the observatory.
In the field of seismology the observatory's programme included the regional study of earthquake waves and the relationship between earthquake waves and the interior of the earth
During World War II, O'Connell collaborated with the United States government in the location of earthquakes in the Pacific zone in relation to war strategy. This work continued after the war. Each week a cabled report was sent to the United States from Riverview. The Imperial War Graves Commission also consulted him concerning possible earthquake damage to war cemetery sites in the Pacific area.
In his role as director of the Vatican Observatory, he began a career of unique service to the Church that spanned the reign of three popes, and saw immense developments in astronomical research from the initial concept of various stellar populations to an expanding universe containing active galactic nuclei and quasars. On a few occasions he organised study weeks of the Pontifical Academy of Sciences, at which these subjects were discussed, e.g. Stellar Populations in 1957, and Nuclei of Galaxies in 1970. As a result of these study weeks, two books were published, both edited by O'Connell, and they became classics of astronomical literature. From 1955-61 he was president of the Commission on Double Stars of the International Astronomical Union.
Of his many contacts with popes he served, his relationship with Pius XII was especially close. He frequently advised the Pope, himself a very keen and diligent student of the natural sciences, on topics of current scientific research. In was under Pius XII that the major modern research tool of the Vatican Observatory, the Schmidt telescope, planned under his predecessors but completed under O'Connell, was inaugurated and blessed. Pius XII often visited the observatory, and on one occasion viewed the launching of the Russian Sputnik.
Paul VI viewed the landing of the first man on the Moon with O'Connell over a specially installed television, and he advised the Pope on the technical details of the mission.
In the pursuit of his scientific research, O'Connell became a close friend and collaborator of an international community of astronomers. As director of the Riverview Observatory he went to Europe in 1948 to attend the first post-war meeting of the International Astronomical Union held at Zurich, and on that occasion visited many European observatories. His visit to Utrecht was noteworthy, for there he established a lifelong friendship with Professor Marcel Minnaert who later encouraged him to issue the now famous book on the Green Flash, which, published in collaboration with Brother Karl Trench SJ, provides excellent documentation on optical effects that occur in the Earth's atmosphere when the sun is rising or setting.
However, O'Connell was best known in the international community of astronomers for his research on double stars. He discovered an effect, since known as the “O'Connell Effect”,
concerning the rotation of the line of the apsides (the major aids of the double star's ellipticalorbit). The discovery of this effect was typical of the scientific work of O'Connell. lt required a long period of painstaking observations and careful analyses over many years.
In addition to his membership in the academies and institutes already mentioned, O’Connell was a member of the National Research Council of Australia, and an honorary member of the Royal Irish Academy He was also a member of the Royal Society of New South Wales, publishing three papers on earthquakes and the Galitzin seismograph. He served on council, 1946-49, and was vice-president, 1950-52. He became an honorary member of the Society in 1953.
O'Connell retired as director of the Vatican Observatory in 1970. He was president of the Pontifical Academy of Science, 1968-72. While he was an indefatigable worker and consequently very jealous of his time, he still treasured his friends immensely, and was always nurturing new friendships. Even during his last years, when he was largely bedridden, he developed new friendships among old and young alike. The students at Riverview remembered him for showing groups of boys the Moon, planets and the stars on clear nights and for his unfailing gracious word and cheery smile for staff and students.
Many were the nights that, under the then clear skies over Castel Gandolfo. O'Connell climbed the stairs to the telescope atop the papal palace passing die plaque inscribed “Deum Creatorurn Venite Adoremus. He was very intelligent, hardworking and always a gentleman genuine international Jesuit.

Note from Noel Burke-Gaffney entry
1950 He was appointed Director of the Observatory at Riverview after Daniel O’Connell was appointed to the Vatican Observatory

Note from William O’Leary Entry
He remained at Riverview until his death in 1939, directing the observatory until 1937 when Daniel O'Connell became director

Note from Edward Pigot Entry
His extremely high standards of scientific accuracy and integrity made it difficult for him to find an assistant he could work with, or who could work with him. George Downey, Robert McCarthy, and Wilfred Ryan, all failed to satisfy. However, when he met the young scholastic Daniel O'Connell he found a man after his own heart. When he found death approaching he was afraid, not of death, but because O’Connell was still only a theologian and not ready to take over the observatory. Happily, the Irish province was willing to release his other great friend, William O'Leary to fill the gap.

Obituary
Fr Daniel O'Connell (1896-1913-1982) (Australia)

I met Dan O'Connell for the first time when I went to the noviciate, then in Tullabeg. I found him a quiet novice but a very pleasant companion. We both went to Rathfarnham and were together in our First Arts year (1916-17). He was a brilliant and highly intelligent man. He took a keen interest in Fr William O’Leary's seismograph, which stood in Rathfarnham grounds, and frequently inspected it with him.
We parted company in 1920, when he went to Valkenburg for philosophy while I followed the subject in Milltown. Two years later we were both posted to Australia. We did not travel there together but met in Riverview College, Sydney, where we spent our regency. In Riverview was the Irish Jesuit, Fr Edward Pigot, who had an astronomical observatory, in which Dan became keenly interested, Fr Pigot himself had erected this observatory and fitted it out with a strong telescope for watching the various stars at night. He was also an accomplished pianist and taught Dan the piano.
In 1926 Dan followed me to Milltown for theology. Together we were ordained there by the Archbishop of Dublin, Dr Edward J. Byrne. Later, whenever Fr Dan came back to Dublin, he stayed with Dr Byrne's successor, Dr John Charles McQuaid, who was a great friend of his, as they had been classmates in Clongowes. Twenty or so years after Fr Dan's return to Riverview, he was called to Rome to take charge of the Vatican observatory, and ended his days in Rome.

The summary notice, taken from L'Osservatore Romano (16th October 1982) and transmitted by Frs Joseph Costelloe and John P. Leonard of the General Curia, fills in some of the external details of Fr O’Connell’s life:
"Yesterday evening, Thursday, 14th October, Fr Daniel O’Connell, former Director of the Vatican Observatory and ex-President Emeritus of the Pontifical Academy of Sciences, died after a long illness in the infirmary of the Jesuit General Curia in Rome.
Born in Rugby, Great Britain, in 1896, he had entered the Society of Jesus in Ireland in 1913. After completing his studies in physics and mathematics at the University College, Dublin, he spent two years of special studies at the Harvard College Observatory in Cam bridge, Massachusetts, between 1931 and 1933.
He then became Director of the Riverview College Observatory in Australia, where he remained until 1952, when he was appointed Director of the Vatican Observatory, which he directed until 1970. From 1968 until 1972, he was, by the appointment of Paul VI, President of the Pontifical Academy of Sciences.
Known for his scientific labours, especially for his researches on double stars - an area in which he discovered a particular effect named after him - Fr O'Connell was a member of many international societies, including The National Research Council of Australia, The Royal Academy of Ireland, and The Royal Society of New South Wales”

Frs George V Coyne and Martin F McCarthy SJ, of the Vatican Observatory brought out a glossy four-page printed leaflet (of A4-size page) as a memorial to their fellow-astronomer and fellow-Jesuit. Five of the photographs therein show Fr O’Connell greeting in turn four recent Popes, including the present one. An interesting account is also given of his astronomical work. The editor of IPN has at his disposal at least one photocopy of this leaflet, which he will gladly send to any contemporary of Fr Dan’s or to any other interested person who might like to have it.
Fr Dan O’Connell contributed two articles to the New Catholic Encyclopedia: “Calendar reform” and “Vatican Observatory”. He featured in past numbers of The Clongownian: 1953, pp. 9-12, “Astronomer and seismologist”; 1968, pp. 42-3; 1974, p. 33 (copy of an autographed letter to him from Paul VI).

Obituary
Fr Daniel O’Connell (1896-1982)
Like William Keane, Daniel O'Connell was a brilliant student who devoted his life to the Lord's work in the Society. He was born at Rugby, England, on 25th July to an Irish father and English mother, At the age of 12 when his parents died, he went to Ireland and completed his secondary education at Clongowes College; in view of his examination results, I presume that he was Dux of his class, as William Keane had been. One of his masters was Henry Johnston, and one of his fellow students was John Charles McQuaid, later a famous Archbishop of Dublin. At the age of 17, he entered the novitiate of the Irish Province at Tullabeg on August 8th, 1913. A fellow novice described him as 'quiet but a very pleasant companion', qualities noted in him throughout his later life which were to win him many friends.

It may be remarked, incidentally, that although he was related to the Liberator' he was called Daniel after another member of the family.
University Studies
University studies were at the National University of Ireland where he did a brilliant scientific course with first class honours in experimental physics and mathematics, ending with a Master of Science. With other scholastics he would have commuted to the University from Rathfarnham Castle, Juniorate residence and later retreat house. In its grounds was a seismograph, erected by Fr. William O'Leary, who was later to take over from Fr. Pigot as Director of the Riverview Observatory. Daniel took a keen interest in this, a fact which was not lost on Fr. O'Leary who was later to choose him as their designate'. For Philosophy, Daniel was sent to Valkenburg in Holland where the German Provinces had their house of studies, having been driven out of Germany by Bismarck's Kulturkampf. Here he pursued part-time studies in astronomy under important German Jesuit scientists. Arrangements had been made for him to enter Cambridge University to study relativity under Sir Arthur Eddington but he experienced a breakdown in health, had lung trouble, and was sent to Australia to recuperate and do Regency. He taught at the observatory in 1923 under Fr. Pigot. The latter was also a fine pianist and taught Daniel the piano.

In 1926 Daniel returned to Ireland for theology, studied at Milltown Park and was ordained on July 31st, 1928 by the then Archbishop of Dublin. Tertianship was at St. Beuno's, Wales(1930-1931).

Further Studies
Destined now to become a professional astronomer, Daniel returned to Australia and the Observatory but the following year went to Harvard for further studies and research at its Observatory, then a great centre of research under Howard Sharpley and others. His principal occupation there was the study of variable stars which he continued throughout life and through which he made his name as an astronomer. In 1948 he was awarded a doctorate in science from the National University of Ireland for outstanding services to astronomy, but he also became interested in seismology and the measurement of time with various types of clocks. (These and other scientific details are taken from a brief memorial bulletin published by the Vatican Observatory after Daniel's death in 1982.)

Riverview Observatory (1933-1952)
After visiting other observatories, he returned to Riverview as Assistant Director of the Observatory, taking over from Fr. O'Leary in 1938 when the latter died on the Riverview golf course. (Fr. O'Leary is remembered at Riverview as the inventor of a Free Pendulum clock of superb accuracy which used to stand in the corridor outside the Rector's room in the old building.)

The Observatory received a small grant (£450 in 1939) from the Australian government. When Daniel took over and for a number of years afterwards it had the only fully equipped seismological station in Australia and its reports appeared in the local papers whenever a major earthquake occurred. Its astronomical work consisted mainly in the photographing of variable stars, a work which Daniel carried out himself in the hours of darkness when others were asleep. The increasing illumination of the skies above Sydney rendered this more and more difficult but he managed to make 20,000 plates over the years.

During his years at the Observatory Daniel became a highly respected figure in astronomical circles in Australia and elsewhere, becoming, for instance, a Fellow of the Royal astronomical Society among other memberships. But he was no remote scholar. He had a gift for popularizing science when this was needed and he was called on occasionally by the ABC for broadcasts. When Fred Hoyle (of Steady State fame) delivered a number of lectures on the BBC on “The Nature of the Universe” Daniel was asked to give three lectures on the ABC on the same topic. He called his lectures “According to Hoyle” and made it very clear that his distinguished counterpart was wrong in dismissing the Creator from the origin of things. Hoyle, who must be a very old man now, is said to be now more in favour of creation, impressed by the 'fine tuning' of the universe.

Riverview
While Daniel did not teach, he was an object lesson to the boys that science and religion could be reconciled. He was also a familiar and friendly priest, whose sermons they listened to in the chapel with more than usual attention. He could get down to their level. There were occasional guided tours of the Observatory - I had some myself when I was at Riverview as a scholastic 1947-1949. He was also a 'good community man'. The only thing that annoyed him was noise, and most particularly the lowing of Brother O'Brien's cows which disturbed his sleep by day after a night of observation. But he did not have recourse to the 'ultimate deterrent' of shooting one or two. He bore it cheerfully enough as he did the loneliness of much of his work. I think of him as a very dedicated, kindly person.

Vatican Observatory
In 1952 news came that Daniel had been appointed Director of the Vatican Observatory located at the papal summer residence at Castelgandolfo in the hills 16 miles from Rome. His appointment was a 'most strict secret', which he observed most faithfully, but it was leaked out over in Rome so he was embarrassed by people asking him if it were true. Due to illness and the necessity of taking up the appointment quickly, he had little time to say goodbye to his many friends in Australia. He left by ship on July 26th, 1952, bringing to an end almost a quarter of a century at Riverview and its Observatory, both of which remained very dear to him.

From 1952 until his retirement in 1970 he was Director at the Vatican Observatory. He was President of the Pontifical Academy of Science from 1968 to 1972. He served three Popes and had close personal relations with them. Over the years he published a number of books (e.g. The Green Flash, Stellar Populations, Nuclear Galaxies) and many papers. The Vatican Observatory gave him much greater scope than he would have had at Riverview. He could do better work and was in contact with a wider group of scientists. There were times when he lamented that he had never given a retreat, but his was a full-time ministry.

Retirement (1970 - 1982)
His health, never very robust, gave him increasing problems so he had ultimately to retire from the Observatory and come to live in Rome at our Curia. The Pope wanted him to stay in Rome and keep in touch with the Pontifical Academy. In August 1973 he was allowed to make a trip to Australia to attend a conference and make contact. Of course, he had always kept in touch and delighted to meet Australian Jesuits studying in Rome. I have very happy memories of meeting with him during the 32nd General Congregation. He had a great memory for the Australian brethren and even for the boys he had known at Riverview.

His health became worse and worse so that for the last two years he was practically bed-ridden. He died in the infirmary at the Curia on October 13th, 1982. The notice in the Osservatore Romano mentioned that he had bore his long illness with marvellous serenity and was comforted by the special blessing of the Holy Father, John Paul II. One can only say that the papal blessing was richly deserved - Daniel O'Connell had been a very faithful servant of the Church in the difficult field of science.
With similar talents and in different ways, William Keane and Daniel O'Connell made very significant contributions to the work of the Province and the Society. As they were men who shared their wisdom with others we may trust that they will shine like stars for all eternity (Book of Daniel, 12:3)

◆ The Clongownian, 1953
Astronomer and Seismologist
Father Daniel O’Connell SJ
THE appointment of Father Daniel O'Connell SJ, director of Riverview Observatory, New South Wales, Australia, since 1938, as Director of the Vatican Observatory in Rome, climaxes a long and eminent career as astronomer and seismologist.
Father O'Connell enjoys world repute as a scientist and he has contributed much to the high reputation enjoyed by the famous Jesuit observatory at Riverview.
He holds the Doctorate of Science of the National University of Ireland and the Docotrate of Philosophy of the Gregorian University of Rome, and is a Fellow of the Royal Astronomical Society.
He was born near Rugby, England, in 1896, of an Irish father, a civil servant and a native of County Limerick, and an English mother. He had two brothers and one sister, all of whom are still living. He went to Ireland as a boy of 12, following the death of his parents, completed his schooling at Clongowes Wood College, and entered the Society of Jesus at Tullabeg at the age of 17.
His family has a 600-years-old affinity with that of “The Liberator”. He was not, however, called after “The Liberator”. The Christian name, Daniel, was traditional in his family.

His first introduction to astronomy was a year's private study with the late Father W O'Leary SJ, a famous Irish Jesuit astronomer and seismologist, who at that stage was Director of the Rathfarnham Observatory from 1929 to 1938. He began by setting up some telescopes at Rathfarnham, largely as a hobby.

Father O'Connell completed his MSc degree at University College, Dublin, in 1920, after a brilliant course of study, specialising in Mathematics and Experimental Plıysics. He topped all his examinations, graduated with first-class honoura, and was awarded a travelling student ship in Mathematics. Whilst he was still an undergraduate he was in charge of the Rathfarnham station for several years after the departure of Father O'Leary.

He completed his philosophical studies at the Jesuit House at Valkenburg, in Holland, where he also pursued spare time astronomical studies under world famous Jesuit scientists like Father Michael Esch SJ, expert on variable stars; Father Franz Xavier Kugler SJ, world authority on Assyriology and Babylonian astronomy, and Father Theodor Wulfe SJ, world-ranking physicist.

Arrangements had been made for him to enter Cambridge University on a travelling scholarship where he would have studied relativity under Eddington, when he experienced a breakdown in health and was sent to Australia by his superiors to recuperate. Prior to this, he had never dreamt of going to Australia, had thought little about that country, and had few friends there.

An interesting and significant incident occurred whilst he was studying at Valkenburg. Seemingly for no apparent reason, Father Edward Pigot SJ, Founder of Riverview Observatory, appeared at the college one day during a visit to Europe. The young Jesuit student met the veteran and conversed with him. He was later invited to accompany him to the railway station to see him off. Just before he boarded his train, Father Pigot mentioned that his real reason for coming was to see the future Director of Riverview and to “look him over”. It was no surprise when he later sought him as his assistant.

Father O'Connell was appointed to St Ignatius College, Riverview as teacher of physics and assistant to the Director of the Observatory, Father Pigot. Father O'Connell is still happy to recall that another assignment in the early days was that of sports master at St Ignatius. In 1923 he was appointed assistant director of the observatory, and one of the first tasks he undertook in his new post was to advance the local study of solar radiation.

Father O'Connell returned to Dublin in 1926 to complete his theological studies and was ordained at Milltown Park by Archbishop Byrne in 1928. After two more years of theological studies he com pleted his tertianship in St Beuno's College, Wales.

During 1931 to 1933, Father O'Connell was a member of the staff of the Harvard University Observatory, renowned for its work on variable stars, where he completed post-graduate studies and research on variable stars and other aspects of astronomy. He published numerous papers in Harvard publications, and has since acknowledged that his work at Harvard was the foundation of his later contribution to astronomy.

During his stay in the United States Father O'Connell visited Mount Wilson and Lick Observatories in California before returning to Australia via Japan, China, Java and the Philippines, where he visited leading observatories and advanced his practical studies. The Lembang Observatory in Java was one that held special interest for him.

Father O'Connell resumed his work at Riverview Observatory at the end of 1933. In 1935 he initiated the “Riverview Observatory Publications”, which now enjoy an international reputation. Later he also founded the observatory's “Geophysical Papers” and “Reprint Series”, which are also known and used internationally. In 1948 Father O'Connell spent 10 months in Europe. He was the Australian delegate at the conference of the International Astronomical Union at Zurich and that of the International Union of Geodesy and Geophysics at Oslo. He spent six weeks at the Vatican Observatory and visited other leading observatories of Europe.

During World War II, Father O'Conneil, working at the Riverview Observatory collaborated with the United States Government in the location of earthquakes in the Pacific zone in relation to war strategy. This work was carried on in the post-war period and is still taking place. Each week a cabled report in code is sent to the United States from Riverview. He was also consulted by the Imperial War Graves Commission concerning possible earthquake damage to war cemetery sites in the Pacific area.

In 1948 Father O'Connell received his Doctorate of Science from the National University of Ireland in recognition of his outstanding contributions to science.

Father O'Connell is a member of leading Australian and overseas societies and other organisations, and has contributed numerous research papers and other writings to their publications and proceedings.

He is a member of the Royal Irish Academy and the international Astronomical Union, Fellow of the Royal Astromomical Society, Vice-President of the Royal Society of New South Wales, member of the National Research Council of Australia and the National Committee on Astronomy, Geophysics and Calendar reform; Chairman of the Board of Visitors of the Commonwealth Observatory, Mount Stromio; Australian representative on the Committee for Seismology of the Pacific Science Commission and member of many other scientific councils and committees in Australia. Father O'Connell resigned from 19.Boards and Committees..

Under Father O'Connell's direction, the Riverview Observatory has conducted a programme of continuous research that has been responsible for important discoveries. In the field of astronomy, eclipsing stars and cepheid variables have received special study. The photographic photometry of these stars has been one of the main aspects of the observatory's programme. Hundreds of new variable stars have been discovered, and much original research has been completed on known stars. About 15,000 plates are on file in the observatory.

Variable stars are those which are con stantly changing in brightness. Another star may move in front of them, they may expand or contract becoming hotter and brighter.

Knowledge of variable stars is highly important and basic to progress in modern astronomy. But for a knowledge of cepheid stars, for example, scientists would not have the faintest notion of the size of the universe,

One of Father O'Connell's latest activities was the use of photo-electric equipment in relation to variable stars.

Father O'Connell is reassured by the knowledge that this and other phases of the work at Riverview will continue and, naturally, it is his hope that necessary staff and equipment will be forthcoming. The fact that the direction will be in the hands of Father Burke-Gaffney gives Father O'Connell confidence in the future work and role of the observatory. Father O'Connell has taken some material on southern stars with him to Rome for completion.

In the field of seismology, the observatory's programme has included the regional study of earthquakes and the relation ship between earthquake waves and the interior of the earth.

The publications of Riverview Observatory are an important aspect of the work. They include four series - the “Seismological Bulletins”, which have appeared since 1909, the “Riverview Observatory Publications”, which began in 1935, the “Reprint” series, which date back to 1936, and the “Geophysical Papers”, which were founded in 1946. All of them are circulated and read all over the world.

The Riverview Observatory, which progressed under Father O'Connell, has never been anything but first-rate. It inherited this tradition from its founder and it was maintained by later directors. Complete accuracy has always been its aim, and all of its work has proved to be as careful and painstaking as human processes can ensure. Its equipment has always been the best available and its overhead has growii in dimension as well.

Father O'Connell left Sydney by slip for Rome on July 26 to take up his net post.

It distressed him that he was unable to make a personal farewell to many of his friends before he left Australia, due to the fact that he was confined to bed until the day before his ship sailed.

Obituary
Father Daniel Joseph Kelly O’Connell SJ
On October 14, 1982, the Jesuit order lost one of the best known of its modern scientists, the internationally acclaimed astronomer: Father Daniel J K O'Connell SJ. After several years of serious and confining sickness, Father O'Connell died peacefully among his Jesuit brothers at the order's headquarters in Rome, where he had settled after his retirement in 1970. In addition to directing the Vatican Observatory from 1952 to 1970, he was President of the Pontifical Academy of Sciences from 1968 to 1972 and President of the Commission on Double Stars of the International Astronomical Union from 1955 to 1961. He served three popes and had close personal relationships with all of them.

Born in Rugby, England, in 1896, he entered the Jesuit order in Ireland in 1913. He received his diploma in experimental physics and a Master of Science degree in mathematics at University College Dublin, and later a Doctorate in Science from the National University of Ireland. He studied from 1931 to 1933 at the Harvard College Observatory, Cambridge, Massachusetts, and was subsequently to have studied with the famous Sir Arthur Eddington. However, because of a lung condition, Jesuit superiors, in order to provide him with a more favourable climate, assigned him to the Riverview College Observatory, Sydney, Australia, where he became director in 1938.

During the years that Father O'Connell was at Harvard, the observatory was at the centre of the major developments in astronomical research and especially those which were to lead within the next few decades to the notion of the expanding universe of galaxies. He was thus associated with such eminent astronomers as Harlow Shapley, Cecilia Payne Gaposhkin, and others. His principal occupation at Harvard, a pursuit which he continued for the rest of his life, was the study of variable stars; but he also became known as a keen card player, especially at bridge. In fact, a story is told of how two young graduate students were duped into an evening of bridge against Father O'Connell and the famous cosmologist Abbé Georges Lemaitre on the occasion of a visit which the latter paid to the Harvard College Observatory. The students, not knowing the true identity of their challengers except that they gave a distinct impression of being neophytes at bridge, since they were overheard explaining to one another in broken English and French the names of the cards, were a bit embarrassed to accept the challenge for fear of crushing opponents to whom they were expected to show at least respectful deference. After a long evening of play the students, soundly defeated and thoroughly deflated, approached the famous Harlow Shapley for an explanation. His only remark to them was that the game must have been both an honest and an intelligent one, at least on the part of the two older gentlemen, since both of them were on the one hand Catholic priests and on the other eminent scientists.

While at the Riverview College Observatory, in addition to his study of variable stars, Father O'Connell, under the tutelage of the famous Father Wm O'Leary SJ, developed a keen interest in seismology and in the measurement of time with various types of clocks. This latter pursuit led him into a life long interest in the calendar and calendar reform, a study which served him well in later decades, since he was asked to advise popes on calendar reform and the cycle of ecclesiastical feasts.

Called to be director of the Vatican Observatory in 1952, Father O'Connell began a career of unique service to the Church which spanned the reign of three popes and saw immense developments in astronomical research from the initial concept of various stellar populations to an expanding universe containing active galactic nuclei and quasars, In fact, during his directorship, once near the beginning and once at the end, Father O'Connell organized Study Weeks of the Pontifical Academy of Sciences at which some of the world's most capable astronomers discussed the topics respectively of Stellar Populations (1957) and Nuclei of Galaxies (1970). As a result of these Study Weeks two books were published, both edited by Father O'Connell, which have become classics of astronomical literature.

Of his many contacts with the popes he served, his relationship with Pope Pius XII was an especially close one. He frequently advised the pope, himself a very keen and diligent student of the natural sciences, on topics of current scientific research. The International Astronomical Society held its triennial meeting in Rome in 1952, the same year that Father O'Connell came as director to the Vatican Observatory. At an audience and reception given by the Pope, the first opportunity was given to the pontiff to appreciate what a qualified representative the Church had in Father O'Connell as an interpreter of the Church's aspirations to the culture of science. It was under Pius XII that the major modern research tool of the Vatican Observatory, the Schmidt telescope, planned under his predecessors but completed under Father O'Connell, was inaugurated and blessed. Pope Pius XII often visited the observatory and, in fact, as a gesture of his interest, came to view through the Schmidt telescope with Father O'Connell on the night when the Space Age was born with the launching of the Russian Sputnik.

Pope John XXIII showed a special affection for Father O'Connell and the observatory staff and not infrequently paid visits to Father O'Connell's office, which was located directly above the Pope's private study. At the time of the landing of the first man on the moon, Father O'Connell had the privilege of viewing the event with Pope Paul VI over a specially installed television and he advised the Pope on the technical details of the mission.

In the pursuit of his scientific research, Father O'Connell was a close friend and collaborator of an international community of astronomers. As director of the Riverview College Observatory, he came to Europe in 1948 to attend the first postwar meeting of the International Astronomical Union held at Zurich, and on that occasion he visited many European observatories. His visit to Utrecht was noteworthy, for there he established a life long friendship with Professor Minnaert who later encouraged him to issue the now famous book on the Green Flash, which, published in collaboration with Brother Karl Treusch SJ, provides excellent documentation on optical effects which occur in the earth's atmosphere when the sun is rising or setting. However, Father O'Connell was best known in the inter national community of astronomers for his research on double stars. He discovered an effect - since known as the “O'Connell Effect”, concerning the rotation of the line of the apsides (the major axis of the double star's elliptical orbit). The discovery of this effect was typical of the scientific work of Father O'Connell. It required a long period of pains taking observations and careful analyses over many years.

In addition to his membership in the academies and institutes mentioned above, Father O'Connell was a member of the National Research Council of Australia, and an honorary member of both the Royal Society of New South Wales and of the Royal Irish Academy

While he was an indefatigable worker and consequently very jealous of his time, he still treasured immensely his friends and was, as a matter of fact, always nurturing new friend ships. Even during his last years, when he was largely bedridden, he developed new friend ships among old and young alike. There was never an international scientific conference attended by Vatican astronomers in the Rome area where the participants failed to request to pay a visit to Father O'Connell. Many were the nights that, under the then clear skies over Castle Gandolfo, Father O'Connell climbed the stairs to the telescope atop the papal palace passing the plaque inscribed thus: Deum Creatorem Venite Adoremus. In serving many, of high and low station alike, he was serving but One, the Creator of all that he observed. For that Daniel Joseph Kelly O'Connell, sj. has been called to his Father and we are happy for him.

astronomer; Catholic priest; meteorologist; schoolteacher; seismologist

Died : 22 May 1929, North Sydney, Sydney, New South Wales, Australia

Edward Francis Pigot (1858-1929), Jesuit priest, astronomer and seismologist, was born on 18 September 1858 at Dundrum, near Dublin, son of David Richard Pigot, master of the Court of Exchequer, and his wife Christina, daughter of Sir James Murray, a well-known Dublin physician. Descended from eminent lawyers, Edward was educated at home by tutors and by a governess. The family was very musical and Edward became a fine pianist; he was later complimented by Liszt. He studied arts and medicine at Trinity College, Dublin (B.A., 1879; M.B., B.Ch., 1882) and also attended lectures by the astronomer (Sir) Robert Ball. After experience at the London Hospital, Whitechapel, he set up practice in Dublin.

In June 1885 Pigot entered the novitiate of the Society of Jesus at Dromore, County Down. He began to teach at University College, Dublin, but in 1888, on account of ill health, came to Australia. He taught at St Francis Xavier's College, Melbourne, and from August 1889 at St Ignatius' College, Riverview, Sydney. Returning to Europe in 1892 he studied philosophy with French Jesuits exiled in Jersey, and theology at Milltown Park, Dublin. He was ordained priest on 31 July 1898. In 1899 he volunteered for the China Mission and was stationed at the world-famous Zi-Ka-Wei Observatory, Shanghai. In 1903, again in poor health, he spent some months working in Melbourne and at Sydney Observatory, and taught for a year at Riverview before returning to Zi-Ka-Wei for three years. Tall and lanky, he came finally to Sydney in 1907, a frail, sick man. He had yet to begin the main work of his life.

On his way back to Australia Pigot visited the Jesuit observatory in Manila: he was beginning to plan an observatory of international standard at Riverview. He began meteorological observations there on 1 January 1908. As terrestrial magnetism could not be studied because of nearby electric trams, he decided to set up a seismological station as the start of the observatory. The Göttingen Academy of Sciences operated the only fully equipped seismological station in the southern hemisphere at Apia, Samoa: a station in eastern Australia would also be favourably situated to observe the frequent earthquakes that occur in the south-west Pacific Ocean. Assisted by the generosity of L. F. Heydon, Pigot ordered a complete set of Wiechert seismographs from Göttingen, and visited the Apia observatory. Riverview College Observatory opened as a seismological station in March 1909. Seismological observations continue to be made there.

A great traveller despite his teaching duties, Pigot visited Bruny Island, Tasmania (1910), the Tonga Islands (1911) and Goondiwindi, Queensland (1922), to observe total solar eclipses; and observatories in Europe in 1911, 1912, 1914 and 1922 and North America in 1919 and 1922. He made observations of earth tides in a mine at Cobar (1913-19), collaborated with Professor L. A. Cotton in measurements of the deflection of the earth's crust as Burrinjuck Dam filled (1914-15) and performed Foucault pendulum experiments in the Queen Victoria Market building, Sydney (1916-17). On 1 September 1923 F. Omori, a leading Japanese seismologist, observed with Pigot a violent earthquake being recorded in the Riverview vault; it turned out to have destroyed Tokyo, with the loss of 140,000 lives.

Fr Pigot was a member of the Australian National Research Council from 1921, president of the State branch of the British Astronomical Association in 1923-24 and a council-member of the Royal Society of New South Wales in 1921-29. On his way back from the Pan-Pacific Science Congress in Tokyo (1926), he visited the observatory at Lembang, Java, where he planned a programme of study at Riverview Observatory of variable stars. Between 1925 and 1929 Pigot measured solar radiation at Riverview and Orange, particularly in relation to long-range weather forecasting. He was seeking a site of high elevation above sea-level for this work, when he contracted pneumonia at Mount Canobolas. He died at North Sydney on 22 May 1929 and was buried in Gore Hill cemetery.

Sir Edgeworth David paid tribute to Pigot:
It was not only for his profound learning that scientists revered him. They could not fail to be attracted by his magnetic personality, for though frail and often in weak health, he ever preserved the same charming and cheerful manner, and was full of eagerness and enthusiasm in discussing plans for the better pursuit of scientific truth. Surely there never was any scientific man so well-beloved as he.

◆ HIB Menologies SJ :
Paraphrase/Excerpts from an article published in the “Catholic Press” 30/05/1929
“The late Father Pigott, whose death was announced last week in the ‘Press’, was born at Dundrum Co Dublin 18/09/1858, of a family which gave three generations of judges to the Irish Bench. He himself adopted the medical profession, and having taken his degree at Trinity, he practiced for a few years in Dublin and at Croom, Co Limerick. While studying at Trinity he made his first acquaintance with astronomy, when he heard a course of lectures by the famous Sir Robert Ball, then head of the Observatory at Dunsink, and Astronomer Royal of Ireland.
In 1885 the young Doctor, already noted for his charming gentleness and self-sacrificing charity entered the Novitiate of the Society of Jesus at Dromore. he made his first visit to Australia as a Scholastic in 1888, and he taught for four years at Xavier College Kew, and Riverview Sydney. Naturally his department was Science.
In 1892 he was sent to St Helier in Jersey to study Philosophy with the French Jesuits who had been expelled from France. It was here that he began his long battle with frailty and illness, during which he achieved so much for scientific research over his 70 years. He did his Theology at Milltown and was Ordained 1899. Two years later he volunteered to join the French Jesuits in China, and this required of him not only his scientific zeal, but also his spiritual and missionary ones. he did manage to master the Chinese language for his work, and he used to tell amusing stories of his first sermons against himself and his intonations. His health was always threatening to intervene, and so he went to work at the Zi-Kai-Wei Observatory near Shanghai. The work he did here on the Chinese Mission was to reach his fulness in the work he later did over many years in Australia, and where he went to find the climate which suited his health better. He received much training at Zi-Kai-Wei and in photography and study of sunspots at Ze-se, which had a twin 16 inch telescope.
1907 saw him back in Australia and he set about founding the Observatory at Riverview, while teaching Science. By his death, this Observatory had a range and capacity, in terms of sophisticated instruments, which rivalled the best Government-endowed observatories throughout the world. Whilst he had the best of equipment, he lacked the administrative personnel necessary to record all the data he was amassing. His great pride towards the end was in his spectroscope for the work on Solar Radiation where he believed that ‘Long-distance weather forecasts will soon be possible, though not in my time’ (Country Life, 29/04/1929). Current farmers and graziers will owe him a lot in the future.
The scientific work at Riverview has received recognition in Australia. Edward’s interests in the Sydney Harbour Bridge, his experiments in earth tremors at the construction of the Burrenjuck Dam, geophysics at the Cobar mines, pendulum experiments in the Queen Victoria Markets of Sydney. In 1910 he took part in a solar eclipse expedition to Tasmania, and in 1911 on the ship Encounter a similar trip to the Tongan Islands, and the Goondiwindi Expedition of 1922.
In 1914 he was appointed by the Government to represent Australia at the International Seismological Congress at St Petersburg, though war cancelled that. In 1921 he was a member of the Australian National Research Council and sent to represent them to Rome at the 1922 first general assembly of the International Astronomical Union and the International Union of Geoditics and Geophysics. He was president of the NSW branch of the British Astronomical Association, and a member of the Royal Society of NSW. In 1923 the Pan-Pacific Science Congress was held in Australia, and during this Professor Omori of Japan was at Riverview watching the seismometers as they were recording the earthquake of Tokyo, Dr Omori’s home city. In 1926 he went to the same event at Tokyo, and later that year was elected a member of the newly formed International Commission of Research of the Central International Bureau of Seismology.
From an early age he was a passionate lover of music, and this came from his family. he gave long hours to practising the piano when young, and in later life he could play some of the great pieces from memory. He was said to be one of the finest amateur pianists in Australia. It often served as a perfect antidote to a stressful day at the Observatory."

Many warm-hearted and generous tributes to the kindness and charm for Father Pigott’s personal character have been expressed by public and scientific men since his death. Clearly his association with men in all walks of life begot high esteem and sincere friendship. Those who knew him in his private life will always preserve the memory of a kindly, gentle associate, and of a saintly religious.”

Edward Pigot's family was of Norman origin and settled in Co Cork. Ireland. The family was a famous legal family in Dublin. He was the grandson of Chief Baron Pigot, son of judge David Pigot, brother of Judge John Pigot. He was the fourth of eight children, and was educated at home by a governess and tutors. The family was very musical, Edward playing the piano.
Pigot went to Trinity College, Dublin, and graduated BA in science in 1879. His mentor at the university in astronomy was Sir Robert Ball, then Royal Astronomer for Ireland and Professor of Astronomy. Pigot then studied medicine and graduated with high distinction in 1882, and after postgraduate studies practiced in Baggot Street, Dublin.
However, Pigot gave up this practice to join the Society of Jesus, 10 June 1885, at the age of 27.
After a short teaching period at University College, Dublin, Pigot was sent to Australia in 1888 because of constant headaches, and he taught physics and physiology principally at St Ignatius College, Riverview, 1890-92. He returned to Europe for further studies, philosophy in Jersey with the French Jesuits, 1892-95, and theology at Milltown Park, Dublin, where he was ordained priest in 1898. Tertianship followed immediately at Tullabeg.
At the age of 41 and in ill health, Pigot volunteered for the Chinese Mission in 1899, and was stationed at Zi-ka-Wei, near Shanghai, working on a world famous observatory, where
meteorology, astronomy and terrestrial magnetism were fostered. Pigot specialised in astronomy and also studied Chinese. Like other missionaries of those days, he grew a beard and a pigtail. However, his health deteriorated and he was sent to Australia in 1903 for a few years. He then returned to Shanghai, 1905-07, before returning to Riverview in 1908.
After visiting the Manila Observatory, he formulated plans for starting an observatory at Riverview, an activity that he believed would bring recognition for the excellence in research that he expected at the Riverview observatory He believed that seismology was best suited to the location. Pigot obtained the best equipment available for his work, with the gracious benefaction of the Hon Louis F Heydon, MLC. He personally visited other observatories around the world to gain ideas and experience, as well as attending many international conferences over the years. One result of his visit to Samoa was the building and fittings for the instruments in the half-underground, vaulted, brick building at Riverview. Brs Forster and Girschik performed the work. Some instruments, called the Wiechert Seismographs, came from Germany.
He became a member of the Australian National Research Council at its inception in 1921, and foundation member of the Australian Committee on Astronomy, as well as that on Geodosy and Geophysics. He served on the Council of the Royal Society of NSW, and was President of the British Astronomical Association (NSW Branch), 1923-24.
The upkeep of the Riverview observatory was borne by the Australian Jesuits and Riverview. Family and friends also gave funds for this work. When he died from pneumonia, he left at the Riverview observatory five double-component seismometers, two telescopes fully equipped for visual and photographic work, a wireless installation, clocks specially designed for extreme accuracy, an extensive scientific library, a complete set of meteorological instruments, and a solar radiation station, possessing rare and costly instruments.
Pigot's work at Riverview included working on scientific problems of the Sydney Harbour Bridge, experiments at the construction of the Burrenjuck Dam, geophysics at the Cobar mines, and pendulum experiments in the Queen Victoria Market Buildings in Sydney In 1910 he took part in a solar eclipse expedition to Tasmania. In April 1911 he went with the warship Encounter on a similar expedition to the Tongan Islands in the Pacific, and was prominent in the Goondiwindi Solar Eclipse Expedition in 1922.
Pigot was appointed by the Commonwealth Government to represent Australia at the International Seismological Congress at St Petersburg in 1914. He was secretary of the seismo-
logical section of the Pan-Pacific Science Congress in Sydney, 1923, and in 1926, once more represented the Commonwealth Government as a member of the Australian Delegation at the Pan-Pacific Congress, Tokyo. In 1928 he was elected a member of an International Commission of Research, which was part of the International Bureau of Seismology, centered at Strasbourg.
He was highly esteemed by his colleagues for his friendship, high scholarship, modest and unassuming demeanour, and nobility of character. Upon his death the rector of Riverview received a letter from the acting-premier of New South Wales, describing Pigot as one of the state's “most distinguished citizens”, and Sir Edgeworth David praised his magnetic personality and eagerness and enthusiasm in discussing plans for the better pursuit of scientific truth.
Edward Pigot, tall and lanky, frail and often in weak health, was also a fine priest, always helper of the poor, and exemplary in the practice of poverty. He did pastoral work in a quiet way. On his scientific expeditions, he was always willing to help the local clergy and their scattered flocks. He was genuinely modest, humble, and courteous to all. Yet he was naturally a very sensitive and even passionate man, with a temperament that he did not find easy to control. He disagreed strongly with Dr Mannix on the issue of conscription - the Pigots were decidedly Anglo-Irish - and positively refused to entertain the idea of setting up an observatory at Newman under the archbishop's aegis.
His extremely high standards of scientific accuracy and integrity made it difficult for him to find an assistant he could work with, or who could work with him. George Downey, Robert McCarthy, and Wilfred Ryan, all failed to satisfy. However, when he met the young scholastic Daniel O'Connell he found a man after his own heart. When he found death approaching he was afraid, not of death, but because O’Connell was still only a theologian and not ready to take over the observatory. Happily, the Irish province was willing to release his other great friend, William O'Leary to fill the gap.

Fr Pigot attended the Pan-Pacific Science Congress in Tokyo as a delegate representing the Australian Commonwealth Government. He was Secretary to the Seismological Section, and read two important papers. On the journey home he spent some time in hospital in Shanghai, and later touched at Hong Kong where he met Frs. Byrne and Neary.

Lavender Bay, Sydney :
Fr. Pigot's great reputation as a seismologist was much increased during the present year by his locating of the Kansu earthquake within a few hours of the first earth tremors. “Where he deserted medicine,” the Herald writes, “that profession lost a brilliant member, but science in general was the gainer. Dr Pigot is one of the world's leading authorities on seismology, and can juggle azimuths and seismometers with uncanny confidence”.

Obituary :
Fr Edward Pigot
Fr Pigot died at Sydney on May 21st. He caught a slight cold which in a few days developed into T. B. pneumonia. He was very frail, and had no reserve of strength left to meet the attack. The Archbishop presided at the Requiem. The Government sent a representative. The papers were all very appreciative.

Fr Pigot was born at Dundrum, Co. Dublin on the 18th September 1858, educated at Trinity College, Dublin, where he studied medicine, and took out his degrees - MB, BCh, in 1882. For the three following years he was on the staff of Baggot St Hospital, Dublin, and was Chemist with his uncle, Sir James Murray, at Murray's Magnesia works. He entered the Society at Loyola House, Dromore, Co. Down on the 10th June 1885. He spent one year at Milltown Park as junior, and then sailed for Australia. One year at Kew as prefect, and three years at Riverview teaching chemistry and physics brought his regency to an end. Fr. Pigot spent three years at Jersey doing philosophy, as many at Milltown at theology, and then went to Tullabeg for his tertianship in 1898. At the and of the year a very big event in his life took place. He applied for and obtained leave to join the Chinese Mission of the Paris province. For a year he worked in the Church of St. Joseph at Yang-King-Pang, and for two more at the Seminary at Zi-Kai-Wei, but the state of his health compelled a rest, and in 1913 we find him once more at Riverview teaching and trying to repair his shattered strength. He seems to have, in some measure, succeeded, for, at the end of the year he returned to his work at Zi-kai-wei. The success however was short lived. He struggled on bravely for three years when broken health and climatic conditions forced him to yield, and he asked to be received back into the Irish Province. We have it on the highest authority that his reasons for seeking the Chinese Mission were so a virtuous and self-denying, that he was heartily welcomed back to his own province. In 1907 he was stationed once more at Riverview, and to that house he belonged up to the time of his happy death in 1929.
It was during these 22 years that Fr. Pigot's greatest work was done - the founding and perfecting of the Riverview Observatory. The story is told by Fr. Dan. O'Connell in the Australian Jesuit Directory of 1927.
Fr. Pigot's first astronomical training was at Dunsink Observatory under the well known astronomer “Sir Robert Ball”. Then, as mentioned above, many years were passed at the Jesuit Observatory at Zi-kai-wei.
For some years previous to his return to Riverview, earthquakes had been receiving more and more attention from scientists, Excellent stations had been established in Europe and Japan, but the lack of news from the Southern Hemisphere greatly hampered the work of experts. It was the very excellent way in which Fr. Pigot supplied this want that has won him a high place amongst the worlds scientists.
Thanks to the kindness of relatives and friends, and to government help, Fr. Pigot was able to set up at Riverview quite a number of the very best and most up-to-date seismometers, some of which were constructed at government workshops under his own personal supervision. At once, as soon as things were ready, Fr Pigot entered into communication with seismological stations all the world over. When his very first bulletins were received in Europe, Riverview was gazetted as a “first-order station”, and the work done there was declared by seismologists everywhere as of first-rate importance. At the time of his death Fr Pigot had established telegraphic communication with the International Seismological Bureau at Strasbourg.
The study of earthquakes was only one of Fr. Pilot's activities, He was able, again through the generosity of his friends, to put up at Riverview, a first class astronomical observatory. It has four distinct lines of research :

1. The photography of the heavens.
2. Photographs of sunspots
3. Study of variable stars.
4. Micrometre measurements of double stars.
   Fr Pigot also took part ill a number of solar eclipse expeditions to Tasmania in May 1910, in April 1911 to Tonga, and to Goondiwindi in 1922.
   Finally, and perhaps most difficult of all, he established at Riverview a solar radiation station. The object of such a station is to determine the quantity of heat radiated out by the sun. This quantity of heat is not constant, as was thought but variable. The work is expensive, and of a highly specialised nature. It was hoped that in course of time it would have very
   practical results, amongst them being the power of being able to forecast changes in climate and weather over much longer periods than is at present possible. The necessary funds were collected by a Solar Radiation Committee formed at Sydney, Supplemented by a legacy from a relative of Fr Pigot's.
   Fr Pigot's ability as a scientist is shown by the number of important positions he held, and by the number of missions entrusted to him. He was elected President of the N. S. W. branch of the British Astronomical Association in 1923 and 1924.
   He was a member of the Council of the Royal Society of NSW for several years. On the occasion of the International Seismological Congress to be held at. St. Petersburg in l914 he was appointed by the Commonwealth Government as delegate to represent Australia. Owing to the war the Congress was not held. It was on this occasion that Fr Pigot was sternly refused permission as a Jesuit to enter Russia. Even the request of the British ambassador at St Petersbourg for a passport was of no avail. It was only through the intercession of Prince Galitzin the leading Seismologist in Russia and a personal friend of the Russian Foreign Minister that the permit was granted.
   He went to Rome in 1922 as delegate from the Australian National Research Council to the first General Assembly of the Astronomical Union.
   He was Secretary of the Seismological Section at the Pan-Pacific Science Congress in Australia 1923.
   He was appointed by the Commonwealth Government as one of an official delegation of four which represented Australia at the Pan-Pacific Congress in Tokyo 1926.
   Fr Pigot was a great scientist he was also a fine musician an exquisite pianist and a powerful one. He was said Lo be amongst the finest amateur pianists in Australia. Once during a villa he was playing a piece by one of the old masters. In the same room was a card party intent on their game. Fr Pigot whispered to a friend sitting near the piano “mind the discord
   that's coming”. It came, and with it came howl and a yell from the card players. In the frenzy of the moment no one could tell what was going to come next. But, as Fr Pigot continued to play a soothing bit that followed, a normal state of nerves was restored, and the players settles down to their game.
   He was a great scientist, and a fine musician, but, above all and before all, he was an excellent religious. In the noviceship too much concentration injured his head, and he felt the effects ever afterwards. It affected him during his missionary work and during his own studies. His piety was not of the demonstrative order, but he had got a firm grip of the supernatural, and held it to the cud. He knew the meaning of life, the meaning of eternity and squared his life accordingly.
   His request for a change of province was in no way due to fickleness or inconstancy. He had asked a great grace from Almighty God, a favour on which the dearest wish of his heart was set, and he made a supreme, a heroic sacrifice to obtain it. That gives us the key note to his life, and it shows us the religious man far better than the most eloquent panegyric or the longest list of virtues that adorn religious life could do. Judged by that sacrifice he holds a higher and a nobler place in the world of our Society that that which his genius and unremitting hard work won for him in the world of science.
   A few extracts to show the esteem if which Fr. Pigot was held by externs :
   Father Pigot's death “removes a great figure not only from the Catholic world but also from the world of science. His fame was world-wide. He was one of the worlds' most famous seismologists”.
   “By his death Australian science and the science of seismology have sustained a loss that is almost irreparable. He initiated what now ranks among the very best seismological observatories in the world”.
   “He was able to secure the best instruments for recording the variations in heat transmitted from the sun to the earth for his Solar observatory at Riverview, and to make observations, which science in time will rely upon to put mankind in the possession of long range forecasts as to future rainfall and weather in general”.
   “Dr. Pigot told me that after some years it would be possible to forecast the weather' two seasons ahead”.
   “ Dr. Pigot was one of the brightest examples of simple faith in a Divine purpose pervading all the universe”.
   “It was not only for his profound learning that scientists reverenced him. They could not fail to be attracted by his magnetic personality, for though frail and often in weak health he ever preserved the same charming and cheerful manner, and was full of eagerness and enthusiasm in discussing plans for the pursuit of scientific truth. Surely there never was any scientific man so well beloved as he”
   “Those who knew him in his private 1ife will always reserve the memory of a kindly, gentle associate, and of a saintly religious”.

Obituary : Fr Edward Pigot
The following items about Fr. Pigot's youth have been kindly supplied by his brother.
“He was born the 18th Sept. 1858 at Meadowbrook, Dundrum, Co. Dublin His first tuition was at the hands of governesses and private tutors, after which he attended for some years a day school kept by H. Tilney-Bassett at 67 Lower Mount St.
Concurrently, under the influence of his music Master, George Sproule, his taste for music began to develop rapidly. Sproule had a great personal liking for him, and took him on a visit to Switzerland. Many years afterwards Fr. Pigot heard that Sproule (who had taken orders in the Church of England) was in Sydney. He rang him up on the telephone, without disclosing identity, and whistled some musical passages well known to both of them. Almost at once Sproule knew and spoke his name.
Even as a schoolboy, I can recall how he impressed me by his superiority, by his even temper, command of himself under provocation, his generosity, his studiousness and his steadiness generally.
He entered Trinity about 1879. In the Medical School, he had the repute of a really serious student. He was especially interested in chemistry and experimental physics. Astronomy was outside his regular course, but I remember visits to Dunsink observatory, His studies seemed to he regulated by clockwork.
Before setting up as a doctor in Upper Baggot Street, he was resident medical attendant at Cork Street Fever Hospital, and the Rotunda Hospital, and at the City of Dublin Hospital. When in private practice at Baggot Street, he was not financially successful. I have the impression that his serious demeanour and grave appearance were against him, But I have better grounds for believing that his work amongst the poor, his unwillingness to charge fees to the needy, operated still more in the same direction. We often heard, but not from him, of his goodness to the poor. This was the time that he announced to us his desire to join the Jesuit Order. May I add that if there was one event in Ned’s life for which I have long felt joy and thankfulness, it was his desire to enter your Order.
Years after he had left Dublin, one of his prescriptions had become locally famous, and was ordered from the chemist as “a bottle of Kate Gallagher, please”, Kate having been one of his poor friends”.

Riverview :

In 1923 Fr. Pigot built a Solar Radiation Station at Riverview, and started a programme of research on the heat we receive from the sun. This work has now been finally wound up. The valuable instruments, which are the property of the Solar Radiation Committee, were offered on loan to Commonwealth Solar Observatory, Mt. Strombo, Canberra. The offer was accepted and the instruments were sent by lorry to Mt. Strombo on February 7th. The results of the work have been prepared for publication and are now being printed. This will be the first astronomical publication to be issued by the Observatory since December 1939. Shortage of staff and pressure of other work during the war were responsible for interrupting that branch of our activities. Another number of our astronomical publications is now ready and about to be sent to the printer. We have started a new series of publications: Riverview College Observatory Geophysical Papers." The first three numbers are now being printed and will be sent to all seismological Observatories and to those scientists who may be interested.

Father Edward Pigott 1859-1929
Fr Edward Pigott was born in Dundrum Dublin on September 18th 1858, of a family which gave three generations to the Irish Bench. Edward himself became a Doctor of Medicine, taking a degree at Trinity College, and practising first in Dublin, then in Croom County Limerick. In 1885, the young doctor entered the Society at Dromore, and made his first visit to Australia in 1888, where he spent four years teaching at Xavier College.

Ordained in 1899, two years later he volunteered for the Chinese Mission. He learned the Chinese language in preparation for his work, and for a while tested the hardships of active service with the French Fathers of the Society. He used recall afterwards with a wry smile his efforts to preach in Chinese, and how he hardly avoided the pitfalls on Chinese intimation. I;; health, which dogged him all his life, sent him to the less arduous work of Assistant at Zi-Kai-Wei Observatory, near Shanghai. This was the beginning of his brilliant career as an astronomer.

After six years in Shanghai, during which he mastered his science, he returned to Australia in 1907 and started the Observatory at Riverview. He started with a small telescope and a few elementary instruments for recording weather changes, and finally made of Riverview, one of the leading Observatories of the world. Honours and distinctions were showered on him. He was appointed by the Government to represent Australia at St Petersburg in 1914, in Rome in 1922, at the International Astronomical Union, and the Pan Pacific Science Congress in 1923, held in Australia.

In spite of his prominence in the scientific world, Fr Pigott remained always to his brethren a kindly and gentle associate and a saintly religious.

He died on May 22nd 1929, aged 70 years, battling with ill health all his life. A strong spirit housed in a frail body.

Father Pigot’s Return

On April 11th, the Community and boys went down to the College Wharf to welconie Father Pigot SJ, back to Riverview, after his extended tour through Europe. He had been absent about seven months, and during that time visited most of the leading seismological observatories on the Continent and in the British Isles. He had purposed visiting also some other observatories in the United States, Canada and Japan, on his return journey to Sydney; but a severe attack of pleurisy in Italy, during the trying mid-winter season, obliged him to hasten back to the warm Australian climate, without even being able to accept the kind invitation of Prince Galitzin to spend a few days as his guest at St Petersburg. All have heard of Father Pigot's application to the Foreign Office, London (on hearing accidentally, a day or two before, of the existence of a Russian law prohibiting members of the Jesuit Order. from entering Russia) to obtain from the Russian Government the necessary permission, in view of a short visit to Prince Galitzin's Seismological Observatory at Pulkovo. The request of the Foreign Office was refused, as everyone knows, but apparently the sequel of the story is not so generally known.

It was during liis stay at Potsdam (Berlin) that Father Pigot received the unfavourable reply from Westminster. He at once acquainted Prince Galitzin with the refusal, whereupon the distinguished seismologist made a strong representation, resulting in his Government immediately withdrawing the prohibition. His kind letter to Father Pigot acquainting him with the Russian Government's concession, and a formal communication to the same effect from the British Foreign Office, arrived during Father Pigot's convalescence, but a delay in Europe of three months would have been necessary to allow the severe winter in St. Petersburg to pass before he could, without risk of relapse, have availed himself of the concession and kind invitation.

Father Pigot has asked us to record his deep feeling of appreciation of the cordial greetings of the Community and boys, when they most kindly came down to welcome him at the wharf,

We give a photograph of Father Pigot, and another of a group of distinguished seismologists assembled together from various parts of the world, at Manchester, for the International Seismological Congress (1911).

Fr Pigot’s Visit to Europe : The InternationalAstronomical Union - First General Assembly, Rome, May 1922

The First General Assembly of the Inter national Astronomical Union commenced its deliberations in May this year, in the Academy of Science (the old Corsini Palace), at Rome. That Australia in union with the other nations, might be represented at the two main conferences (Astronomy, and Geodesy and Geophysics), the Commonwealth Government having paid the necessary subscriptions, three delegates - Dr T M Baldwin (Government Astronomer for Victoria), Mr G F Dodwell (Government Astronomer for South Australia), and Father Pigot represented the Australian National Research Council at the General Assembly.

The purpose of the Union, as set forth in this report, is - (I) “To facilitate the relations between astronomers of different countries where international co-operation is neces sary or useful; and, (2) To promote the study of astronomy in all its departments”. Each country adhering to the Union has its own National Research Council, which forms the National Committee for the promotion and co-ordination of astronomical work iul the respective countries, especially regard ing their international requirements. The countries at present adhering to the Union are Australia, Belgium, Brazil, Canada, Czecho-Slovakia, Denmark, France, Great Britain, Greece, Holland, · Itály, Japan, Mexico, Poland, South Africa, Spain, and the United States.
When Father Pigot left us suddenly in March, we felt that indeed there must be “something on” in the scientific world to draw him away at short notice from his beloved observatory. But the meetings of the Astronoinical Union, despite their international importance, were not his only objective. His itinerary, as we shall see, was a long one, and one of his chief aims while in Europe and America, was to inspect the principal Astronomical, Seismological and Solar Radiation observatories, and to get in personal touch with the foremost scientists. of the northern hemisphere.

Upon arrival in Europe he spent some time, successively, in the observatories of Marseilles, Nice, Geneva, and Zurich, In April he attended the Seismological Congress at Strasbourg, and then went on to Rome, taking in on his way, the Arcetri Observatory at Florence (situated, by the way, a stone's-throw from Galileo's house). While in Rome at the Conferences of the Astronomical and Geophysical Unions, he was, of course, in constant touch with Father Hagen S J, the Director of the Vatican Observatory, and though he does not say so, we may well imagine that his feelings were not untinged with sadness as he ascended the great staircase of the Government Observatory-the great Roman College of the Jesuit Order, before a Ministry more sectarian than honest usurped it.

Before the Conferences of the General Assembly were over, the delegates were in vited by His Holiness the Pope to a special audience in the Throne Room of the Vatican. It was accepted by all. Before congratu lating themselves on the splendid success of their meetings, His Holiness spent some time in chatting freely with most of those present, shook hands with them all, and be fore their departure, had a photo taken by the Papal photographer in the Court of St. Damasus.

The Roman Conferences over, Father Pigot lost no time in getting on his way. His first call was at the Geophysical Institute of Göttingen. Then on to Munich, and to Davos Platz for a private meeting on Sky and Solar Radiation with Dr Dorno (Head of Davos Observatory), Professor Maurer (Head of the Swiss Weather Bureau), and Professor Kimball (of the Solar Radiation Station of the Washington Weather Bureau).

The Paris Observatory - one of the largest in Europe - came next, and after spending some time here, he went on to the Royal Observatory at Brussels. Before leaving Beigium, he had time to run down to the Jesuit Observatory at Valkenberg, near the Dutch frontier, after which he returned to Greenwich. At a dinner of the Royal Astronomical Society, at which nine of the delegates were entertained, Father Pigot's health was proposed by Father Cortie SJ, of the Stonyhurst Observatory.

After a brief visit to Ireland, Father Pigot started out on his return journey, via America. One of his first visits on the other side was to the Jesuit Seismological Observatory at Georgetown University, Washington. While in the Capital, he spent some time at the Carnegie Observatory (Terrestrial Magnetisın), the Weather Bureau Solar Radiation Station, the Astro-physical Observatory of the Smithsonian Institute (where he renewed acquaintance with a valued friend, Dr Abbot, the President), the Bureau of Standards, and the Office of the Geodetic Survey. He was much impressed, as in 1919, with the up-to-date appliances of the Americans, and with the thoroughness of their scientific work.

Leaving Washington, he called at The Observatory of Harvard University (Boston, Mass.), and at the University of Detroit, where he found Professor Hussey, who knows Riverview well and has been in Australia more than once on scientific work. Yerkes Observatory, near Chicago, where is installed the largest Refractor in the world, claimed him next, after which he proceeded to the famous Mt Wilson Observatory at Pasadena (near Los Angeles, Col.). Here Father Pigot was in his element, for it is with Dr. Abbott, more especially than any one else, that he has discussed the details of the projected Solar Radiation Observatory at Riverview, and from him received the most valuable assistance.

Passing on to the Lick Observatory (Mt Hamilton, N Cal), he just missed Professor Campbell, who had left for Australia four days before as a member of the Wallal (WA) Eclipse Expedition. Professor Tucker, however, the locuin tenens, showed hiin every kindness.

Father Pigot's final visit before embarking for Australia was to the Canadian Government Observatory (Victoria, BC), which possesses the most powerful telescope in the British Empire (73in. Reflector). In the realm of instrumental astronomy Canada has outstripped all the other Dominions, and even the Mother Country herself.

It is superfluous to emphasise the immense value Father Pigot derived from his visits to the leading scientific men of the world, picking up hints, seeing new methods, and the most modern appliances for the subject nearest and dearest to his heart.

That the Riverview Observatory will gain by his experiences, and that the new Solat Radiation Observatory will receive a new fillip, goes without saying:

Obituary

Edward F Pigot

Father Pigot was born at Dundrum, County Dublin, on September 18, 1858. He adopted the medical profession, and practised for a few years in Dublin. In 1885 he entered the Novitiate of the Society of Jesus at Dromore, County Down. He made his first visit to Australia as a Jesuit scholastic in 1888, and taught for four years at Xavier College, Melbourne, and St Ignatius' College, Sydney. Naturally, his department was science. He completed his theological studies in Milltown Park, Dublin, and was ordained in the summer of 1899. Two years later he volunteered for the arduous China Mission, where the French Fathers of the Society of Jesus were endeavouring to Christianise the vast pagan kingdom - an act revealing fires of missionary zeal and personal devotion probably unsuspected by those who knew only the retiring scientist and scholar of later years. His sacrifice was accepted, and recompensed in a striking manner. He did, indeed, master the Chinese language in preparation for missionary labours, and for a while tasted the hardships of active service.

He returned to Australia in 1907, and immediately set about founding an observatory at Riverview, while teaching science on the college staff. When death called him he had gathered at Riverview five double-component seismometers, two telescopes fully equipped for visual and photographic work, a wireless installation, clocks specially designed for extreme accuracy, an extensive scientific library, a complete set of meteorological instruments, and what he most valued in his later years, a solar radiation, station, possessing rare and costly instruments, such as are possessed by only a few other, and these Government-endowed, stations throughout the world.

Fr. Pigot's in terest in the scientific problems of the Sydney Harbour Bridge, his experiments at the construction of the Burrenjuck Dam, in geophysics at the Cobar mines and elsewhere, his pendulum experiments in the Queen Victoria Market Buildings in Sydney, are well known. In 1910 he took part in a solar eclipse expedition to Tasmania; in April, 1911, he went with the warship Encounter on a similar expedition to the Tongan Islands in the Pacific, and was prominent in the Goondiwindi Solar Eclipse Expedition in 1922.

Father Pigot was appointed by the Commonwealth Government to represent Australia at the International Seismological Congress at St. Petersburg in 1914. The outbreak of war prevented the Congress being held. In 1921 he was chosen as a member of the Australian National Research Council, and in 1922 went to Rome as its representative at the first general assembly of the International Astronomical Union, and of the International Union of Geodetics and Geophysics. He was elected President of the NSW branch of the British Astronomical Association in 1923 and 1924. For many years he was a member of the Council of the Royal Society of NSW.

At the Pan-Pacific Science Congress, held in Australia in 1923, Father Pigot was secretary of the seismological section. In 1926 Father Pigot was once more chosen by the Commonwealth Government as a member of the Australian Delegation at the Pan-Pacific Congress, held in Tokyo, in October, 1926. In December of last year he received word from the secretary of the Central International Bureau of Seismology, Strasburg, that he had been elected member of an International Commission of Research, formed a short time previously at a congress held in Prague, Czecho-Slovakia.

Many warm-hearted and generous tri butes to the kindliness and charm of Father Pigot's personal character have been expressed by public and scientific men since his death. Clearly his associa tion with men in all walks of life begot high esteem and sincere friendship. Those who knew him in his private life will always preserve the memory of a kindly, geritle associate, and of a saintly religious. RIP

22nd May, 1929.
Dear Sir,
At a meeting of the Cabinet this morning mention was made of the sad loss this State has sustained in the death of Reverend Father Pigot, one of its most distinguished citizens. I was invited by my colleagues to convey to you, as Principal of the eminent educational establishment, with which Father Pigot had the honour to be associated, an. expression of the deepest sympathy from the Members of the New South Wales Ministry.

The memory of Father Pigot, who was a personal friend of many of us, will be kept ever green by reason of his high scholastic and scientific attainments, modest and unassuming demeanour, and easy of character.
Yours faithfully,

Acting Premier,

The Rev Father Lockington SJ, StIgnatius' College, Professor

H, H. Turner, of the British Association and the International Seismological Summary, speaks of “the splendid work done by Father Pigot in seismology; Riverview has been for many years our standby in the discussion of earthquakes near Australia”.

Professor Sir Edgeworth David, quoted in the “Catholic Press”, writes:

“By his death Australian science and the science of seismology have sustained a loss that is almost irreparable. He initiated what now ranks among the very best seismological observatories in the world. He was able to secure the best instruments for recording the variations in heat transmitted from the sun to the earth for his solar observatory at Riverview, and to make observations. This science in time we will rely upon to put mankind in possession of long range forecasts as to future rainfall and weather in general.

He was well known to all leading physicists and astronomers, and entirely because of his great reputation the University of Sydney was able to borrow for a period of six years some extremely valuable pendulums from Germany for measuring small displacements of the earth's crust at the great reservoir at Burrenjuck.

It was not only for his profound learning that scientists reverenced him. They could not fail to be attracted by his magnetic personality, for though frail and often in weak health, he ever preserved the same charming and cheerful manner, and was full of eagerness and enthusiasm in discussing plans for the better pursuit of scientific truth. Surely there. never was any scientific man so well beloved as he”.

The New Seismographs at Riverview

That Seismology, and especially Seismographs, are in the air at present, there can be no doubt. We have recently experienced in Sydney such a series of earthquake tremors, some of which have been usually large, and all coming on top of one another, as it were, that the subject was a common topic of conversation for several weeks. But the greatest interest centred not so much on the earthquakes as on the Riverview Seismograph that recorded them. When, a few weeks ago, the papers announced that a big and destructive earthquake had occurred so many thousands of miles away, "A big earthquake somewhere," one Melbourne Daily headed the re port-the safe announcement following that it was possibly in the sea somewhere, did much, we are sure, to nullify any exciting effect the tid ngs might have had on even unsceptical readers. The news two days later, however, that a severe earthquake had taken place in Sumatra, and that 250 people had been killed, made the Riverview Seismograph not only known, but famous. With Father Pigot's permission (or, shall I say, with out Father Pigot's permission?) I purpose giving a short account of the Seismographs to accompany our illustrations,

The idea, as a mere remote possibility, of starting a Seismographical Observatory at Riverview, occurred to Father Pigot a few years ago at Zi ka-wei (Shanghai), just when leaving for Australia, where he was oblijed by ill-health to return, and received a fresh impetus when he was passing through Manilla on the voyage south. The splendid seismographical work done by the Fathers for many years at these two great Jesuit Observator ies of the Far East (not to speak of all that they have achieved in their other departments, viz., Meteorology, Terrestrial Magnetism, and Astro nomy, above all, of the tens of thousands of lives saved by their typhoon warnings during the last thirty years), was a sufficient incentive to Fr Pigot, who had been on the staff of the former Observatory for some time, to attempt a small beginning of at least one branch of similar high class work in Australia. No doubt excellent records had been obtained for several years in Australia and New Zealand by the well-known instrument of the veteran Seismologist, Professor Milne; but it was interesting to see what results would be obtained by a more modern type of Seismograph of one or other of the recent German models. Those of Professor Wiechert, of Gottingen University, were decided upon, if funds would permit. The decision was most unexpectedly confirmed by the arrival in Sydney shortly after, on his way home to Germany, at the expiration of his term of office as Director of the Samoa Observatory, of Dr Linke, who showed his Wiechert earthquake records to Father Pigot, at Riverview. Dr Linke, who now, by the way, is Director of the Geophysical Institute in Frankfort (Germany), has since taken the kindliest interest in our embryo Observatory.

But where was all the necessary money to come from? Needless to say, a lot of expense was involved. As two of the principal instruments are now installed, we may say that nearly the whole of the expense of the larger (horizontal) Seismograph was defrayed by our kind and generous friend and neighbour, the Hon Louis F Heydon, MLC - a man whose charity is equalled only by his love of learning and scientific progress ad majorem Dei gloriam. To the Hon Mr Heydon, therefore, for the great pioneer part he played in giving Seismology a foothold in Riverview, not Father Pigot's alone, but Riverview's warmest thanks are due. But though Seismology has certainly got a foothold in Riverview, it must be remembered that at present our Observatory is only in an embryonic condition. Space has been provided in the building for other Geophysical re search work, to be carried out later on, when, like the Hon. Mr. Heydon, other lovers of scientific research shall have recognised in the Riverview Observatory, a work deserving of their patronage and generosity.

In July, 1908, Father Pigot paid a visit of three weeks to Samoa, where, through the kindness and courtesy of the Director of the Observa tory, Dr. Angenheister, and his assistants, he was able to study the construction and working of the various instruments, the methods for the reduction of the records, etc. On his return, he set about erecting the building and fittings for the instruments the half-underground, vaulted, brick building (not as yet covered with its protecting mantle for tem perature), and woodwork fittings. These were admirably constructed respectively by Brother Forster SJ, and Brother Girschik SJ, with their usual indefatigable care. In the early autumn the instruments arrived from Germany, and soon afterwards they were recording tremors and earthquakes. The instruments are amongst the most modern in use at the present day, and are known as the Wiechert Seismographs or Seismometers, named from their designer, Professor Wiechert. Until quite recently they were not numerous, being confined, with the exception of the Samoa instrument, to European Observatories. Now, however, they are being installed in various regions of the globe. The extreme delicacy of the instruments is almost incredible; an unusual weight on the floor of the Observatory (a party of visitors, for example), even at some distance from the instruments, would be sufficient to cause serious derange ment of the recording pens; the ocean waves dashing on the coast six miles away on a rough day are frequently recorded. It is in this extreme delicacy that the value (and, incidentally, the trouble) of the instruments consists. As a consequence they demand the most careful handling, and almost constant attention.

There are two instruments: a Horizontal Seismograph and a Vertical Seismograph, to receive, as the names suggest, the horizontal part (or component, as the scientists call it), and the vertical part respectively of the earth-waves set up by any seismic disturbance. The Horizontal Seismograph, however, consists practically of two Seismographs in as much as it separates the waves it receives into two directions; NS and EW, giving a separate record for each, as may be seen from the two recording rolls hang ing down in front.

The horizontal is an inverted pendulum whose bob is a large iron cylindrical (or drum-shaped) mass of 1000 kilograms, or a little over a ton weight. This mass is supported on a pedestal which is poised on four springs set on a large concrete pillar built on the solid rock, and separated from the surrounding floor by an air-gap one inch wide. When an earth quake occurs in any place, that place becomes the centre from which earth waves travel in all directions, through the earth and round the earth (surface waves). These waves on reaching Riverview disturb our concrete pillar, and set the pendulum in motion. The iron mass is reduced to a "stable equilibrium” by a system of springs, so that when the base is disturbed, the large mass will not fall over, but will oscillate or swing backwards and for wards till it comes to rest again. Now, a very ingenious air-damping arrangement (the two drum-like structures over the mass) destroys the oscillation or swing set up in the mass by the first wave, so that the second and third and succeeding earth-waves will not be affected by the oscillation of the mass itself, but each wave, no matter how quickly it comes after the others, will have its own effect on the mass. Consider, for illustration sake, one of those now-antiquated punching-ball apparatus that consist of a heavy leaden circular base, into the middle of which is inserted a stout four or five-foot cane, on the top of which is fixed the punching ball. When you punch this ball it and the cane oscillate, or swing backwards and forwards (the heavy base remaining stationary). If you determine to hit out at this ball at a fixed rate, say thirty punches a minute, you cannot be certain that every blow will have its full effect on the ball-in many cases you may not hit the ball at all. But if you contrive to make the ball stationary, so that it keeps still, or moves very little, when you punch it, every punch, no matter at what rate you punch it, will catch the ball and have its full effect upon it. In somewhat the same way our large iron mass is kept as stationary as possible, by the damping cylinders, while each earth-wave has its full effect upon it. This effect is received by the arrangement of levers above the mass, and magnified enormously, which magnified effect is traced by the recording stylus or pen--a tiny platinum pin-on the smoked re cording roll of paper, Waves coming in a N or S direction are recorded on one of the rolls; those in an E or W direction are recorded on the other, while waves coming in any other direction are recorded on both.

The Vertical Wiechert Seismograph is a Lever-Pendulum, consisting of an iron mass of 160lbs. weight at the end of an arm (under the wooden temperature-insulation box), and a spiral spring (enclosed in the box) be tween the weight and the fulcrum, the weight and the spring keeping the arm of the lever in equilibrium. Hence this pendulum can move only up and down, only by the vertical part of the earth-waves. The effect, as before, is highly magnified and recorded by the stylus. The damping (drum-like) arrangement in this instrument is seen at the left-hand back corner of the table. The temperature-insulation box is simply a double-walled wooden jacket packed with carbon, to protect the spiral, as well as a zinc-steel grid iron compensation, from change of temperature. One of the greatest difficulties with these instruments is keeping the instrument room at the same temperature always. For this reason the brick building is not yet nearly completed, as it will have to be covered by a thick layer of protecting material, which will finally have to be covered by a proper roofing. Again, scientifically inclined and generously disposed friends, please note!

To lessen any disturbance from the room itself (visitors, etc.) the floor of the building is covered with sand to the depth of a few inches, and in the case of the Horizontal, an air gap to the depth of a few feet separates the instrument from the surrounding floor.

The records, which are changed every twenty-four hours, are traced on specially-prepared smoked paper, and can be fixed at once with a suitable varnish. On the instruments, the records are stretched by drums which, by a very nice clock-work device (c.f, weight and escapement) are rotated once every hour, and moved to the right at the same time. Furthermore, by an ingenious electro-magnetic contrivance connected with a Wiechert contact-clock (seen with the Vertical Seismograph), the hours and minutes are accurately recorded on the earthquake tracing itself, and not at the side. Consequently, the exact second almost at which a distur bance begins is known. The rate of tracing is about fourteen millimetres per minute for the Horizontal, and ten millimetres per minute for the Vertical Seismograph.

To the uninitiated, at least, the results in the matter of records are really marvellous. They are worth the trouble they entail, and they do en tail lots of trouble. So far, there have been records of at least four considerable earthquakes (one of which has been already identified), as well as eight or nine smaller ones. Some of these have probably been subma rine, and can be localised when reports come in from other distant Observatories. There is one more point to be treated in this rather crude explanation, and it will explain the last sentence. How is the distance of the earthquake ascertained? Well, in a large seismic disturbance, if situated at a considerable distance, preliminary earth tremors or short waves precede the long earthquake-waves. The distance of the centre of the disturbance (which usually lasts for an hour or two) can be calculated from the time elapsing between the first preliminary tremors, and the beginning of the long waves. Consequently when three Observatories sufficiently distant and suitably situated calculate the distance of a particular shock, say, in mid-ocean, the actual centre can be found by simple geometry.

I have tried to give a simple, straightforward, unscientific explanation of the instruments, without going into more detail than was absolutely necessary. In fact, it would be unwise to go into much detail, for, if I did, I should probably become helpless very soon, and should require a kind and helping hand from Father Pigot to extricate me. But the calculations involved are terrific—a fact that will appear plausible when we say (I have it on Father Pigot's word) that the pressure of the stylus on the record, equivalent to a weight of one milligram, must be allowed for in the reductions of the observations.

Letters from Our Past

Father Edward Pigot SJ

China

Father Pigot SJ, whom our past students of late years will remember, writes from the Shanghai district: to somewhat the same purport :

“Oh, if we only had a few thorough-going Irish priests here, how many more poor Chinese could be received into the Church! In some parts, as in the North, and in Father Perrin's section, one priest more would nean the certain conversion of hundreds and hundreds of Pagans. But Father Superior is at the end of his tether and can not send any more men just now; for the Christian villages around here cannot be left without their missionaries”.

In another letter, dated October of present year, Father Pigott writes :

“Here in our mission, as indeed throughout nearly the whale of China, things are quiet enough : how long it will last I do not know, The Boxers have lately broken out again in the south-west. We had many deaths this past year among our missionaries, and are badly in want of men, especially in the newly opened up districts in the north and in parts of the west of our mission. I send you the lately published yearly “Resumé” of the Kiang Nan. It is, above all, in the Sin-tchcou-fou (Western) Section that the greatest movement of conversion has taken place recently among the people whole villages sometimes asking
