A century of innovation in diabetes care
Before the discovery of insulin, diabetes was a fatal condition.
In 1921, at the University of Toronto, Sir Frederick G. Banting, Charles Best, and John Macleod discovered the molecule of insulin. On 11 January 1922 Leonard Thompson, a 14-year-old boy living with diabetes, became the first person to receive an injection of insulin.
Insulin has since saved millions of lives, representing one of the greatest medical achievements of all time, but more remains to be done.
