THE NOBEL PRIZE OF 1923
Banting and Macleod were awarded the Nobel Prize in Physiology or Medicine in 1923 for the discovery of insulin. Banting split his part of the prize with Best and Macleod split his with Collip.
Insulin is not a cure for diabetes; it is a treatment. It enables the diabetic to burn sufficient carbohydrates, so that proteins and fats may be added to the diet in sufficient quantities to provide energy for the economic burdens of life.
-Frederick Banting, Nobel lecture
