1921 INSULIN

Insulin is central to the treatment of diabetes, as all types of diabetes occur due to the body's inability to use blood sugar efficiently as a result of insufficient, ineffective, or nonexistent insulin supplies.

The discovery of Insulin occurred in 1921 following the ideas of a Canadian orthopedic surgeon named Frederick G. Banting, the chemistry skills of his assistant Charles Best, and John MacLeod of the University of Toronto in Canada.

They received a Nobel prize for this.
