Overview

Frederick Grant Banting (November 14, 1891 – February 21, 1941) was a Canadian surgeon and researcher best known for his role in the discovery of insulin. His work helped convert diabetes from a fatal disease into a manageable condition and made him an international figure in medicine.

Early life and medical career

Banting trained in medicine in Canada and later worked at the University of Toronto, where he developed the idea that led to isolating the pancreatic extract that lowered blood sugar. Before his breakthrough he practiced as a general practitioner and served in the medical corps during the First World War, experiences that shaped his clinical focus and research approach.

Discovery of insulin

In 1921 Banting began laboratory work with medical student Charles Best and others to extract a substance from the pancreas that regulated blood sugar. Their experiments, aided by biochemist James Collip and supported in the laboratory by physiologist J.J.R. Macleod, led to extracts that could treat experimental diabetes and soon after were used in human patients.

Awards and recognition

In 1923 Banting was awarded the Nobel Prize in Physiology or Medicine, shared with J.J.R. Macleod. He later shared his portion of the prize money with his collaborator Charles Best. Banting has been widely honored in Canada and internationally for the impact of his work.

Later life and legacy

Banting continued medical research and public service until his death in a plane crash in 1941. His contributions are remembered through museums, academic chairs, and institutions bearing his name. Banting's work not only saved lives but also established a model for translating laboratory discoveries into clinical therapies.
