  Dr. Andrew Thomson (1893-1974)
Andrew
            Thomson

Dr. Andrew Thomson retired from government service in 1959 and died in 1974 so most people working in Canadian meteorology today never knew him. To those surviving retirees who joined the Meteorological Service during World War II, however, Dr. Thomson will always remain a very important person in their meteorological world. As Assistant Controller he was the man who had the final word on whether or not you were hired and where you were posted, and he was the man with whom you visited if you ever had the opportunity to go to Toronto on leave. Few of us ever saw, let alone had the opportunity of talking with, the Controller (director) at that time, Dr. John Patterson. While there were usually a few experienced meteorologists at Headquarters to look after the training courses and to administer the postings and other details, we knew that behind it all was "Andy" Thomson who had the last word regarding the wartime Meteorological Assistants (BA meteorologists) hired for service with the British Commonwealth Air Training Plan.

If Andrew Thomson ever became exasperated with his young meteorologists and their vocal (and in retrospect very selfish) clamorings for postings nearer home, and their constant demands to be put into RCAF uniform, he didn't show it. Well he might have, however, since he had had a most unusual and widely travelled career - working and studying in several countries after graduation and had accumulated a wealth of experience before returning to Toronto late in 1931 to join the Meteorological Service.

Of Scottish descent, Andrew Thomson was born at Dobbinton, near Owen Sound, Ontario, on May 18, 1893. He graduated in Honour Physics from the University of Toronto in 1915, and returned for a Master's degree in 1916, after which he was awarded a Townsend Fellowship at Harvard University. In May 1917 the Carnegie Institution of Washington, D.C. employed him and later that year he became a mathematical aide to Thomas Edison. Following a brief period in the U.S. Army, he rejoined the Carnegie Institution and in 1919 was sent to northern Brazil to observe the atmospheric effects during an eclipse of the sun.

In October 1919, Dr. Thomson accepted an opportunity to carry out atmospheric electricity research on a voyage of the brigantine Carnegie around the world. During the voyage, which lasted more than two years, Dr. Thomson became fascinated with the South Pacific. Consequently, when the opportunity arose in 1922, he accepted the directorship of the geophysical observatory at Apia in Western Samoa. The territory was then under the trusteeship of New Zealand and, in 1929, Dr. Thomson moved to that country where he was employed as an aerologist. The following year, however, he decided he needed some refresher training and so went to Europe to study in Germany and Norway. In the latter country he became a good friend of Dr. Jacob Bjerknes and the other Norwegian meteorologists who had developed, a few years earlier, the basic air-mass and frontal theory.

Following study in Europe, Dr. Thomson returned to the Carnegie Institution in Washington, but he had retained his Canadian citizenship, and soon decided to return to this country. In January 1932, he took up an appointment as head of the Physics Division at the Headquarters of the Meteorological Service of Canada. In the Service, the long regime of Sir Frederic Stupart had come to a close in 1929 and Dr. John Patterson had been appointed Director. Primarily because of the demands of aviation, increased governmental attention was being given to meteorology at this time, and it was realized that to provide the service required, the new meteorological theories and methods had to be used. However, soon after Dr. Thomson arrived back in Toronto, and before much expansion could take place, the Great Economic Depression snuffed out any real development of meteorological services.

Hampered by a slashed budget, Dr. Thomson became the prime organizer and promoter for two programs that began in 1933-34. The first was the organization of Canadian participation in the second International Polar Year. The first such year in 1883-84 had seen the establishment of observing posts in Canada by the United Kingdom and the United States, but the Meteorological Service had not participated. This time, however, and largely through Dr. Thomson's efforts, there were four special Canadian observing stations - Coppermine, Chesterfield, Cape Hope's Advance and Meanook, Alberta, all staffed by keen young scientists selected and recruited by him. This was Canada's first participation in an international geophysical research program - it was successful and it spurred research in Canadian universities and government at the very time it was needed. Dr. Thomson's other special project during his first years in the Service was the planning and organization of an M.A. course in Meteorology at the University of Toronto, the first in Canada, to be given in cooperation with the Meteorological Service. He planned well; both the course and the cooperation remained for decades with hundreds of graduates.

In spite of the Economic Depression, aviation continued to develop rapidly in Canada during the mid-1930s and it became necessary for the government to plan for substantial meteorological services to support it. Accordingly, in November 1936, the Meteorological Service became the Meteorological Division of the Air Services Branch of the new Department of Transport. Dr. Thomson became the Assistant Controller of the new Division, although he was not officially appointed to the position until early in 1940. To again refresh himself in the rapidly developing field of meteorological theory, Dr. Thomson spent six weeks during 1937 visiting the meteorological services in Britain, Norway and Germany. Later the same year he participated directly in the first forecasting work at Botwood in Newfoundland for experimental trans-Atlantic flying, and in 1938 he was instrumental in staffing and setting up forecast centres across the country for the first flights of the new Trans-Canada Airlines (today's Air Canada). Shortly after the outbreak of war in September 1939 the British Commonwealth Air Training Plan was conceived and Dr. Thomson became the main organizer and administrator of the extensive meteorological program that was subsequently required. Dr. John Patterson was, of course, the Controller throughout the 1930's and during the war; some retired meteorologists may recall that all the correspondence coming out of Toronto headquarters in those days bore his signature. Dr. Thomson did admit, later, that early in the war Dr. Patterson had him learn to sign a passable "J. Patterson" so that there would be continuity in all written orders coming out of headquarters regardless of where Dr. Patterson's duties took him!

Wartime administration of meteorology in Canada must have been a terrific burden on John Patterson and Andrew Thomson. Dr. Patterson, then in his early 70's, and Dr. Thomson were called upon to expand the Meteorological Service nearly tenfold within a very few years. At first, the RCAF told them that 27 meteorological officers would be needed at about two dozen training stations. Every few months the estimated need increased until by 1943-44 there were nearly 350 wartime meteorologists on duty at approximately 70 training and operational bases. In addition, the civil aviation networks of observing stations and forecast centres were expanded in size and activity. College and high school graduates had to be found and trained as meteorologists and technicians; instrument procurement became very difficult; coordination with the American and British military meteorological services was not always easy, nor were dealings with federal manpower and finance officials. A few meteorologists were taken from operational duties to assist in the administrative and training work, but the continuing and prime responsibility for the program rested with Dr. Thomson. In 1944, however, flying training began to be phased out and after mid-1945 the wartime meteorological system was quickly dismantled. As Dr. Patterson was nearing the end of his career, Andrew Thomson now took on the problem of how best to organize Canadian meteorological services for peacetime.

Named an Officer of the British Empire in 1946 for his wartime contributions, Dr. Thomson became Controller of the Meteorological Service later that year. His first accomplishment was the organization of headquarters into an administrative structure that was to last for more than 25 years. He selected for his first divisional chiefs P.D. McTaggart-Cowan, A.J. Connor, R.C. Jacobsen, D.C. Archibald, J.R.H. Noble, and E.W. Hewson, and these men began to plan for and build a bigger and better Service. As a result of retirements and resignations during the first few years, C.C. Boughner, H.H. Bindon and D.P. McIntyre were added to this echelon and similarly left their marks on Canadian meteorology.

During the immediate postwar years Dr. Thomson became the Meteorological Service's first Ottawa commuter as he made almost weekly visits to Transport and other departmental headquarters. The Ottawa trips took longer in those days - Dr. Thomson would catch the 11:20 p.m. sleeper from Toronto and, if he was fortunate, return the next day on the afternoon train leaving Ottawa at 3:00 p.m. If his meetings lasted all day he would return on the sleeper to Toronto, or perhaps spend another night and day in Ottawa.

It was also during this period that Dr. Thomson began to boost Canada to a rather prominent place in international meteorology. During August 1947 he was the host at Toronto meetings of the nine Technical Commissions of the then long-established International Meteorological Organization. In the years that followed he was one of the founders of the present World Meteorological Organization and served for many years on its Executive Committee; this required long trans-Atlantic flights for the annual meetings in Geneva. During these years, before the introduction of jet aircraft, Dr. Thomson became a virtual globetrotter, visiting his fellow directors of meteorology in Africa, Asia and Australasia, as well as in the countries of Western Europe. At home he was host at the combined Royal Meteorological Society-American Meteorological Society meetings at Toronto in 1953, and assisted in sponsoring the Toronto meetings of the International Union of Geodesy and Geophysics in 1955. Over the years Dr. Thomson maintained contact with many of the world leaders in meteorology - if retained and published, his exchanges of correspondence with them would make a very interesting and valuable volume.

Within the public service Dr. Thomson was not only a very resourceful administrator in dealing with departmental and other government people in Ottawa, but he was also one who got things done in his own Service. Some retirees may have vivid memories of his unannounced tours through the offices at headquarters during which he would stop at a desk and ask innocently "And what are you doing today, Mr. ...?". It didn't take many visits of this kind to spur young meteorologists into not only being sure of what they were doing, but also to have a special little study underway which could be reported to Dr. Thomson. Very active in the Royal Society of Canada and always looking for papers for it, "AT" frequently encouraged a meteorologist to complete his study and present the results to the Society at its next annual meeting.

In 1952 Dr. Thomson was awarded the Gold Medal of the Professional Institute of the Public Service of Canada - an honour which only a few public servants ever acquire. In 1958 McGill University honoured him with an honorary degree of Doctor of Science, and in 1965 a few years after his retirement, he was awarded the Patterson Medal for his outstanding contribution to Canadian meteorology. The citation, which accompanied the award, emphasized Dr. Thomson's leadership in forging a link between the universities and the government service, and stressed his service to international meteorology through his lengthy membership on the Executive Committee of the World Meteorological Organization. <

When he retired in 1959, Dr. Thomson had presided over a period of rapid and remarkable growth of the postwar Meteorological Service. The rate of growth that the Service had acquired during wartime did not diminish during the postwar period. In 1946, when Dr. Thomson took over control, the budget of the Service was less than three million dollars, but by 1959, his last year in the Service, it had reached $13,500,000. Accounts of the achievement of the Meteorological Service during those postwar years are to be found in the Annual Reports and histories of the Service; they include marked advances in forecasting services, research, instrument development, climatology and training methods as meteorology flourished in Canada as never before. The man who presided over all of this was Andrew Thomson.

A founder of the Canadian Branch of the Royal Meteorological Society in 1939, Dr. Thomson never ceased being a supporter of it and its successor, the Canadian Meteorological and Oceanographic Society . From 1967 to 1973 he subsidized the Society's "Andrew Thomson Undergraduate Student Prize." Later his name was given to the Andrew Thomson Prize in Applied Meteorology, a prize first given in 1966, the inaugural year of the Society, for outstanding contribution to the application of meteorology in Canada.

After he returned to Canada in 1932, Andrew Thomson married Lally Fleming, a member of a well-known Toronto family who owned the Toronto Street Railway, among other things. They had one daughter, Ellen, who married Dr John Spiers, a leading cardiologist. Mrs. Thomson was a gracious hostess who often entertained meteorologists and their wives at their home on Russell Hill Road; she predeceased Dr. Thomson.

Andrew Thomson was a unique figure in Canadian meteorology for more than forty years, and is, in many ways, responsible for the stature the Meteorological Service attained, both in government circles and in the public domain. Few men have been so devoted to the subject of meteorology, and it would be difficult to find anyone who contributed so much to the Canadian meteorological scene. Dr. Thomson died in Toronto on October 17, 1974.
