On today’s date in 1923, University of Toronto doctors Frederick Banting and John Macleod jointly won the Nobel Prize for Medicine for the discovery of insulin, which has since saved the lives of millions of diabetics.
They were the first Canadians to win a Nobel Prize.
In 1998, the Royal Canadian Mint celebrated the discovery by featuring Banting on a $100 14-karat Proof gold coin. The coin, which was designed by Robert-Ralph Carmichael, depicts the Flame of Hope, an eternal flame kindled in 1989. It will be extinguished only when a cure for diabetes is developed.
Although insulin is not a cure for diabetes, its miraculous arrival in the early 1920s is considered one of the biggest discoveries in medicine.
