Banting, Sir Frederick Grant


Banting, Sir Frederick Grant
born Nov. 14, 1891, Alliston, Ont., Can.
died Feb. 21, 1941, Nfd.

Canadian physician.

He taught at the University of Toronto from 1923. With Charles Best, he was the first to obtain a pancreatic extract of insulin (1921), which, in the laboratory of J.J.R. Macleod, they isolated in a form effective against diabetes. Banting and Macleod received a 1923 Nobel Prize for the discovery of insulin; Banting voluntarily shared his portion of the prize with Best.

 Canadian physician who, with Charles H. Best (Best, Charles H.), 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 his achievement.

      Banting was educated at the University of Toronto, served in World War I, and then practiced medicine in London, Ont. In 1889 Joseph von Mering and Oskar Minkowski had found that complete removal of the pancreas in dogs immediately caused severe diabetes. Later scientists hypothesized that the pancreas controlled glucose metabolism by generating a hormone, which they named “insulin.” However, repeated efforts to extract insulin from the pancreas ended in failure, because the pancreas' own digestive enzymes destroyed the insulin molecules as soon as the pancreas was ground up.

      In May 1921 Banting and Best, a medical student, began an intensive effort in the laboratories of the Scottish physiologist J.J.R. Macleod (Macleod, J.J.R.), at the University of Toronto, to isolate the hormone. By tying off the pancreatic ducts of dogs, they were able to reduce the pancreas to inactivity while preserving certain cells in the pancreas known as the islets of Langerhans, which were thought to be the site of insulin production. Solutions extracted from these cells were injected into the dogs whose pancreas had been removed, and the dogs quickly recovered from their artificially induced diabetes. Banting and Best were able to isolate insulin in a form that proved consistently effective in treating diabetes in humans. This discovery ultimately enabled millions of people suffering from diabetes to lead normal lives.

      Banting and Best completed their experiments in 1922. The following year Banting and Macleod received the 1923 Nobel Prize for Physiology or Medicine for the discovery of insulin, though Macleod had not actually taken part in the original research. Angered that Macleod, rather than Best, had received the Nobel Prize, Banting divided his share of the award equally with Best. Macleod shared his portion of the Nobel Prize with James B. Collip, a young chemist who had helped with the purification of insulin. In 1923 Banting became head of the University of Toronto's Banting and Best Department of Medical Research. Banting was created a knight of the British Empire in 1934. He was killed in a plane crash in 1941 while on a war mission.
