During 1930-31 he studied in Edinburgh, London and Vienna, and from the latter he introduced the Hofmeister-Finsterer gastrectomy to North America. He established himself as a leader in gastro-intestinal surgery, and pioneered the surgical therapy of ulcerative colitis. With H F Moseley he edited a McGill-Royal Victoria *Textbook of Surgery*. He was a charter Fellow of the Royal College of Physicians and Surgeons of Canada and a member of its Council 1949-53; he was a Vice-President of the American College of Surgeons 1950-51.
