Fr. Ingram remains in the United States for another year; he has accepted a Fellowship in the Californian Tec. at Pasadena, where he will have opportunities of research work in seismology under two eminent theoretical seismologists, Guttenberg and Richter and the distinguished instrument designer, Benioff.

New York, 23rd September :
“I have spent some time at Buffalo and Boston and at the Massachussets Institute of Technology. The Professors there were most kind, and I learnt a good deal. I expect to be here for a month or six weeks, visiting factories and Colleges in New York. I met Fr. Ingram at Boston. He was doing some work at Harvard. I have heard from several sources that he had a great reputation at Johns Hopkins. I went yesterday to the Reception for Mr. Costello at Fordham and the conferring of an Honorary Degree. Cardinal Spellman was there. In his speech Mr. Costello avoided politics, except to say that the Government would stop emigration altogether, save that they would still send priests and nuns wherever they might be required. Most of the speech was taken up with a very graceful tribute to the Society and its work. He referred to the debt of Ireland to the Society in times of persecution, and again in modern times, and hoped to see an extention of our work in schools and Colleges in Ireland. The address was broadcast”.

Fr. Ingram, writes from Holy Family Church, 1501 Fremont Avenue, South Pasadena, California, 25th October :
“I am living in a parish rectory (not S.J.) to attend Cal-Tech. It takes me about 20 minutes to get to the Institute by street car. The nearest S.J. house is about 13 miles from Cal. Tech, more than 1 hour by bus and not practical... All my work to date is geophysics. I shall not leave U.S.A. until probably July.
You wonder what life is like in a Seismological Observatory. I report at the Institute in the morning at 8 a.m. and take in a lecture or two. If time permits before lunch I am taken out to the Pasadena Observatory and help in the morning work of inspecting the charts for earth tremors. As there are two or three small shocks nearly every day, this is quite a job. Then we shuttle back to the Faculty Club for lunch and back again to the Observatory in the afternoon - the professors supplying transport. At 5 p.m, we depart from the several different works that the Observatory is handling. I return to my parish to join the pastor and senior curate at supper. By the way, all pastors out here are Irish - very much so - mine played in an All-Ireland in 1911, and his friend, Fr. Masterson, was one of the greatest footballers Cavan ever had, playing for 6 years in All Irelands, etc., 1916-22”.

From Fr. R. Ingram, Holy Family Rectory, 1501 Fremont Ave., South Pasedena, Cal., U.S.A. :
“I have just missed a trip to the Marshall Islands and Hawaii. Shell Ox Co. is sponsoring a world-wide experiment op gravity observations to be taken simultaneously at many different stations. We had arranged a party to take the observations in the Pacific, they were to be made every 1 hour, and the Navy had agreed to co-operate by flying the personnel and instruments to the locations. But an automatic recorder was perfected by La Coste (the designer of the ‘gravy-meter’) and off he went alone. God bless American efficiency! Instead of fiying across the Pacific a party of us have charge of the observations for the Los Angeles region. We hope to get a lot of information.
I plan to leave the West for St. Louis at the end of July. I sail for Ireland with Frs. Kent and Keane on 7th September”.

35 Lower Leeson Street
In the closing days of September we heard with sadness and shock the news that our Superior, Fr. Ingram, was seriously ill. He had gone to hospital with what appeared to be a slight but painful injury to the shoulder. Medical tests were soon to reveal that the cause of trouble was leukaemia in a form so acute that the end could not long be delayed. He died peacefully on the morning of Friday, 6th October. President de Valera was present at the solemn Mass of requiem, In the huge congregation representatives of the two Universities, of the Dublin Institute for Advanced Studies, of the Royal Irish Academy and of other learned bodies were conspicuous. Father Tyndall was celebrant of the Mass, with Fathers O Catháin and Troddyn as deacon and subdeacon. For the Month's Mind there was a Mass in our community chapel, celebrated by Father Troddyn and attended by the Ingram family... father and mother, twin brother and three sisters. These met later the Fathers of the house and expressed their deep appreciation of this small act of courtesy and gratitude. Perhaps the finest tribute to Father Ingram's memory was paid by a colleague in U.C.D. who said “He was the kindest man I ever knew”.

Obituary :

Fr Richard Ingram SJ (1916-1967)

“Dick” Ingram was born in Belfast on 27th July, 1916, one of twin boys. His father, John Ingram, was an Inspector in the then Department of Agriculture and Technical Instruction, who later was largely responsible for drafting the legislation which brought the present Vocational and Technical Education system into effect in 1930. Dick's mother, Edith Kelly, came of a Galway family which settled in Dublin.
His family moved to Dublin, after a spell in Cork, about 1922 and the children were sent to a private school in Rathgar where the intelligent lady principal was so much ahead of her time that the boys began Algebra and Geometry at the age of 8 or 9. So Dick had an early introduction to mathematics. He and his twin brother, Jack, went on to school in Belvedere. There he played Rugby pluckily on the fringe of the teams in his age-class, but cricket was the game which really attracted him, and he was on the Senior XI in his final year, 1933. In class, the fact that he shone less at languages than at mathematics kept him away from the top until he distinguished himself by taking first place in Ireland in Physics in the Leaving Certificate. He entered the Society at Emo that year, on 7th September, 1933.
One might say that he remained a novice, in the best sense, all his life. He never lost the regularity of observance of spiritual duties, the habit of punctuality, the non-equivocating acceptance of obligation and a considerable measure of simplicity, which mar ked him from then on. A fellow-novice recalls something which may illustrate this. Perhaps because he was over-studious, or perhaps from his cricket-playing, Dick had badly hunched shoulders. The Master of Novices proposed a remedy, and for months Brother Ingram was to be seen at voice-production every morning walking around resolutely with a walking-stick tucked through his elbows and behind his back, to straighten him up. Many years afterwards he would say his Office in the garden at 35 Lower Leeson Street, walking as if the stick was still there.
For some years after 1935 experimental-science degrees were out of favour for Juniors, so - despite his Leaving Certificate distinction - Dick did Mathematics and Mathematical Physics at Rathfarnham. He had a remarkable power of application to his studies, which became increasingly apparent and he seemed to feel almost a special vocation, rather than a personal ambition, to do well it mathematics. In this he succeeded, taking First Honours in all his examinations and being one of four Juniors who were chosen to do fourth years in 1938-39. Meanwhile, in his first year he worked at the Seismograph Station with Mr. (now Fr.) Joe McAsey, and was in charge of it himself for the next three years. Earthquakes were never quite obedient to the Juniors' order of time, and plotting their epicentre at odd and even late hours often provided a welcome break in routine. .
In the B.Sc. examination of 1935 Dick was disappointed to be ousted from first place by a few marks by Sheila Power, afterwards a colleague of his at U.C.D. as Mrs. Tinney, but he made no mistake the following year when he took his M.Sc, and beat her and all-comers for the N.U.I. Travelling Studentship in Mathematics. As the Second World War had just begun he was allowed to postpone taking up the studentship, and went to Tullabeg for Philosophy. Along with one other philosopher Dick took up an option given him by the Provincial, Fr, Kieran, of doing the three-year course in two years, and the whole time-table was re-arranged to suit them. Thus they were faced with the formidable task of beginning right away with the third-year as well as the first-year subjects. Having successfully negotiated this crash-course, and securing a further postponement of his studentship, Dick went straight on to Milltown Park in 1941.
In a sense he was returning home, His parents lived at Dartry, half-way between Milltown and Rathfarnham, and from then until his death, save during his four years in America, he seldom missed a Sunday visit to them. Dick was no socialite, and these visits were quiet family affairs which he valued for the pleasure he knew they gave to his mother and father.
Dick took his theology studies and examinations with the serious thoroughness he had given to mathematics, and passed the Ad Gradum successfully in 1945. He had been ordained on 31st July 1944 by the Archbishop of Dublin. He did his tertianship at Rathfarnham, 1945-6, under Father Hugh Kelly.
The time had come to take up the long-postponed studentship. This was no easy matter, for a great deal of mathematics can be forgotten in seven years devoted to other demanding work. Not only that but, during those years, Mathematical studies had moved away from the Cambridge Maths. Tripos pattern little changed from the end of the nineteenth century to the time Dick did his M.Sc. Now, after the war, newer approaches were in vogue. Dick. was not deterred, and he was fortunate enough to find a friendly sponsor for his postgraduate studies at Johns Hopkins, America's foremost mathematical university, in Professor F. D. Murnaghan, a distinguished U.C.D. graduate. He worked for two years under other mathematicians of world-wide reputation, and obtained his Ph.D. degree with distinction in 1948.
During the following year he did further work at the California Institute of Technology, Pasadena. He appears to have enjoyed this year more than any other in his life, save perhaps that spent later as a Visiting Professor at Georgetown University, Washington. He lived at the rectory of a friendly pastor whom he helped with Church work on Sundays and with whom he played a regular game of golf. “We both ‘shot in the middle eighties’”, he said on his return home. It was towards the end of that year that he was to have been flown by the U.S. Air Force to be an observer of a test atomic explosion in the Pacific. The trip, to his disappointment, was cancelled at the last minute because an instrument was found to do the observations automatically.
With his very high-ranking degree Fr. Ingram was sought after by many Jesuit universities in the United States, and he could have had various appointments had he wished to “push” for them, but instead he returned to take up in 1949 what was at first a relatively unimportant lecturership at U.C.D. Indeed, although he passed through several grades of appointment there, it was not really until 1966, when he became Associate Professor of Mathematics in Modern Algebra, that he was given a status in keeping with his qualifications. In his formal application for that post he was able to mention, in an incomplete list, ten contributions of research papers to scientific journals, as well as membership of the Council of the Royal Irish Academy and the Fellowship of the Royal Astronomical Society.
From 1949 to 1963, save for a further year in America (1961 62), Fr. Ingram was stationed at Rathfarnham Castle. He made his Solemn Profession there on 2nd February, 1951. He took charge again of the Seismogaph Station, re-organising its work on a thoroughly scientific basis. As a result of contacts he made in the U.S. in 1961-62 he was offered additional equipment in that year, but he judged it better that this should go to a new station at Valentia which then took over the Rathfarnham work, as is more fully reported in the Province News for January 1963.
That number of the Province News also gives an account of a visit through the Iron Curtain to Jena in Eastern Germany which Fr. Ingram made for a European Seismological Congress in Summer 1962. He attended many such conferences as representative of University College, Dublin. It was typical of him that he regarded them not as sight-seeing holiday trips, nor yet as instructive through the papers heard, but as occasions for making “fruitful personal contacts in one's own field”, as he said on his return from the last one he was at, in Oxford, this Summer. As a result, indeed, he had correspondence with mathematicians in many parts of the world. His friendly manner as well as the fact that he could talk and write on their own high level of knowledge helped him to get on well with these men, often scientists of inter national repute. He was not unaware either that this is a form of Christian witness regarded as essential for the Church by Vatican Council documents. One such scientist, Dr. Cornelius Lanczos, now at the Dublin Institute for Advanced Studies, writes of him in the Winter 1967 issue of Studies : “The premature death of this great scientist and much beloved human being left an irreparable void in the Irish intellectual scene”.
Dr. Lanczos's tribute appears at the end of a review of the book which occupied much of Fr. Ingram's time during the last five years, the monumental (672 page) Volume III of the Mathematical Papers of William Rowan Hamilton, which he edited with Professor Halberstam (of T.C.D. and Nottingham) for the Royal Irish Academy. Into this exacting work he put an immense amount of careful scholarship at a level which even the mathematically illiterate can infer from the review quoted. It was a consolation to Fr. Ingram's community that he had had the sati faction just before he fell fatally ill of distributing the first half dozen copies of the book to some of his professor friends.
How highly these friends and other colleagues regarded him is shown by a tribute published in the Sunday Press of 8th October, 1967 from the pen of Dr. J. R. Timoney, Professor in the Mathematical Faculty at U.C.D., reprinted in part at the end of this notice.
Fr. Ingram was mainly responsible for the foundation of the Irish Mathematical Teachers' Association in 1963 and he devoted himself with characteristic enthusiasm to making it the success it has become. A good deal of the work of preparing its regular News Letters was done, synonymously, by him.
Father Ingram was appointed Superior of 35 Lower Leeson Street in August 1963. It was not an ideal appointment. The office was a burden to him which his shyness especially made difficult. He felt responsibility too heavily : he was a poor conversationalist, and awkward in meeting strangers : he felt hurt if his authority seemed not to be respected or if his opinion was not asked for, even in small matters. These were defects of his qualities. His contacts with University Hall students illustrate both. On the one hand he was most thoughtful in arranging each year to, drive some of them out to Belfield for early morning maths lectures : on the other he was fussy about their tenure when they played in the handball alley at the back of 35. Again, although he was most anxious to be hospitable to visitors he found it difficult in practice to reconcile this with his own rather rigid attachment to an almost monastic way of life. But here, once more, his personal friendliness made up for the shyness which merely meant that nature had not made him the perfect “mine host”. He could and did win many hearts, even in occasional contacts. Thus, when the news of his death got abroad on Friday, October 6th, it was no matter for surprise to see the number of telegrams and letters of sympathy that began to arrive. Many of these were from priests, brothers and nuns for whom he had conducted seminars in the teaching of mathematics, and who now recalled above all his courtesy, patience and humility. But what was really astonishing was the number of neighbours in Leeson Street single-room dwellers for the most part, clerks, typists, shop-hands who stopped Fathers in the street to express their grief at the sudden passing of the gentle priest who had always a cheery good-morning or good evening for them as he hurried along. And nearly all of them said that they had only learned he was Superior of the house from the obituary notice in the newspapers.
Father Ingram's pupils praised him highly for the obvious care with which his lectures were prepared, but even more so for his accessibility and helpfulness out of class. He sometimes mystified them - as must happen with a difficult subject and a professor whose standards are high and exacting - and here perhaps there peeped out a little touch of natural playfulness which for the most part was kept controlled almost to the point of suppression. This was a pity, but for it the fault lay less with Dick than with a traditional system of formation less favoured today than formerly. It did not make him less a good man, a fine Jesuit or a holy priest.
Inevitably newspaper obituaries listed “Professor Ingram's” academic achievements. They remain on record. But those who lived close to him realised that between the status of priest and that of professor he esteemed the former faraway first. Those who served his morning Mass in Leeson Street could not fail to notice the care with which he vested for the altar, his scrupulous observance of the rubrics, the atmosphere of recollection that he radiated. And when in turn he served his priest-server's Mass there was a punctiliousness and decorum about him that would do credit to a novice. He said the Sunday Mass for the domestic staff and the greater part of his Saturday evening was spent in preparing the Sunday homily. Opportunities for Saturday confessions seldom came his way, but when they did he took them eagerly. The Director of Retreats could testify to the humble thankfulness of Dick on being assigned to give a retreat or triduum. His solicitude for the sick in nearby '96' or the Pembroke was just another characteristic of his priestliness. Late on Friday nights anyone who called into the chapel would become aware in the dim light of Dick doing the Stations of the Cross. His piety was never obtrusive but no one could fail to notice it. He could be seen at his rosary more than once a day, and his beads were seldom out of his hand during his last illness.
He liked simple fun at recreation, and the little light reading he indulged in was always of an uncomplicated kind. He enjoyed a good game of golf and almost to the day when he went to hospital to die he was a regular swimmer at the Forty-foot.
The fatal illness was mercifully brief, A shoulder sore all through the Summer did not improve under massage : in early September there was loss of weight and a general feeling of sickness and, finally, double-vision. On 20 September, having said Mass with difficulty, he went into hospital. Blood and other tests were made and meanwhile his condition deteriorated from day to day. A diagnosis of leukaemia was confirmed, and Fr. Shaw, (Spiritual Father) gave him the Last Sacraments on Saturday, 30 September. For the next few days Fr. Tyndall (Minister), visiting him regularly, found the Superior clear in mind only at intervals. Perhaps he did not fully realise how near he was to death. His one anxiety was about the effect his illness would have on his parents, both in their eighties. They saw him for the last time on Tuesday, October 3rd. Next evening he said, only half consciously, to one of his community : “I told them I was all right”. Under sedation all day on Thursday, he was deeply unconscious when two of the Fathers saw him and gave him a last blessing at about 8 o'clock. The special nurse who was attending him wrote afterwards :
“When I arrived on duty at 10 p.m, on Thursday night Father was in a coma and did not speak at all : he went deeper into unconsciousness towards Friday morning at 4.15 a.m. I had lighted the Blessed Candle and had said the prayers for the Dying, then the other nurses on duty joined me in saying the Rosary. Father seemed very peaceful in his last moments : at 4.30 a.m., without any struggle, he just gave a long sigh and his suffering had come to an end”.
It was the First Friday, 6th October. Father Ingram was just over 51 years of age.

REVEREND R. E. INGRAM - A TRIBUTE

By PROFESSOR JAMES RICHARD TIMONEY

It is an understatement to say that everyone connected with mathematics in Ireland, and many not directly involved in that discipline, has been deeply shocked by the almost sudden death of Fr. R. E. Ingram, S.J. The simple title “Fr. Ingram”, is used here for he was always referred to in this way during his life.
It is not necessary to recall the brilliant mathematical career and achievements of Fr. Ingram, for these have been dealt with in many places since his death. What is not so well known is the great human personality which was behind the kind and unassuming exterior which he presented to the outside world. He was kind, humble and always cheerful.
He was a simple man, without a trace of vanity, and although he had a very heavy work-load at all times, he seemed to have plenty of time to listen to all who approached him for help with their problems.
Not only his students will recall the kindly unhurried manner in which he dealt with their difficulties, but also many people who in recent years consulted him about unusual problems in computer programming.
The poser of a seemingly impossible problem who had given up hope, would receive, after a few days, a neatly written note containing an elegant solution.
Fr. Ingram was a natural priest, for such was his great humanity that although his deep simple piety was evident, one forgot that he was a priest. In religious discussion he was tolerant and open-minded but quietly firm. When he thought the occasion demanded it, he could be outspoken and bluntly critical.
The mathematics departments in University College, Dublin, and all interested in mathematics have lost a great and enthusiastic colleague by his untimely death. The best tribute his many friends can pay to his memory is to carry on his work in the many fields where he laboured.

Obituary

Father Richard E Ingram SJ (OB 1933)

Father Richard Ingram SJ, died on October 6th, 1967 after a brief illness. At the time of his death he was Associate Professor of Mathematics at UCD and Superior (since 1964) of the Jesuit House of Studies in Leeson Street. Born in Belfast in 1916, he entered the Society in 1933 and soon gave evidence of outstanding ability. He obtained his BSc in Mathematical Science with first class honours in 1938 and won the MSc and travelling studentship in the following year. As the latter had to be postponed because of the war he resumed his ecclesiastical studies and was ordained in 1944,

Returning to Mathematics in 1946 he went to Johns Hopkins University, obtaining there the PhD degree with the highest distinction in 1948. For the following year he held a Fellowship at the California Institute of Technology. In 1949 he was appointed Lecturer in the UCD Mathematics Dept and at the same time became Director of the Seismological Observatory at Rathfarnham Castle. In 1961-2 he acted as Visiting Professor of Mathematics at Georgetown University, Washington DC, and also did research work for the US Coast and Geodetic Survey. In 1966 he was appointed Associate Professor of Matematics (Modern Algebra) at UCD.

Among his other distinctions Fr Ingram was a member of the Royal Irish Academy and a Fellow of the Royal Astronomical Society. As well as representing UCD at various conferences he contributed research papers to many mathematical journals and conducted Courses in Modern Mathematics for Secondary Teachers. On of his most important undertakings-in conjunction with Professor H Halbestam of Nottingham University was the editing of the third volume of the works of Sir William Rowan Hamilton, a very substantial scientific work which was published this summer.

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)

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.
