Toronto's Historical Plaques
Learn a little of Toronto's history as told through its plaques.
John James Rickard Macleod 1876-1935
Here at 45 Nanton Avenue in Rosedale is a 2006 Heritage Toronto plaque attached to a fence. It says:
J.J.R. Macleod lived here from 1919 to 1928. Born in Scotland, Macleod joined the staff of the University of Toronto as professor of physiology in 1918. In research conducted through his university laboratory from 1921 to early 1922, the collaborating team of Macleod, Frederick G. Banting, Charles H. Best and James B. Collop, isolated the internal secretion of the pancreas, and named it "insulin". Early clinical trials produced sensational results - injections of insulin miraculously saved starving diabetics from certain death. Insulin has since saved the lives of millions of patients around the world. For their discovery, Macleod and Banting were jointly awarded the 1923 Nobel Prize for medicine and physiology, which they shared with their colleagues. Macleod later returned to Scotland where he died in 1935.
