Sir Frederick Grant Banting

Born 14 Nov 1891; died 21 Feb 1941 at age 49. Canadian physiologist and physician who, assisted by Charles H. Best, was the first to extract (1921) the hormone insulin from the pancreas. Injections of insulin proved to be the first effective treatment for diabetes, a disease in which glucose accumulates in abnormally high quantities in the blood. Banting was awarded a share of the 1923 Nobel Prize for Physiology or Medicine for this achievement.
