GEORGE AD AMI was a great pathologist, though not a ‘laboratory man’ in later years. A scholar and Darwin prizeman of Christ's College, Cambridge, he took a first class in the Natural Science Tripos, then studied in Paris with Pasteur and Roux, in Breslau with Heidenhain, and in Cambridge with Roy and Michael Foster. Afterwards he became John Lucas Walker student, and at the early age of thirty, professor of pathology and bacteriology at McGill University, Montreal. Through his inspiration, Sir Humphry Rolleston has written: “a continuous stream of papers” issued “from his laboratory dealing with all branches of pathology and its application to other sciences.” He was awarded the F.R.S. in 1905 and the Fothergillian gold medal of the Medical Society of London in 1914. He was an ex-president of the Association of American Physicians, a fellow of both Jesus and Christ's Colleges, and held many honorary degrees. During the War, Adami became assistant director of Medical Services in the Canadian Army, for which he received the C.B.E. A member of the War Office Committee on the Medical History of the War, he published in 1918 vol. i of the “War Story of the Canadian Medical .Corps.” He was chairman of the Committee on Bacteriological Procedures, Medical Research Committee, and was largely responsible for the standardisation of Wassermann technique in the laboratories of Great Britain.
