The Discovery of 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 James Collip under the direction of John MacLeod of the University of Toronto in Canada. In 1921, Dr. Frederick G. Banting became the first individual to isolate the secretions from the islet cells and tout them as a potential treatment for diabetes.
He observed that other scientists might have failed to find insulin because digestive enzymes had destroyed the insulin before anyone could extract it.
Several conflicting accounts of the discovery of insulin have circulated over the years, and even the Nobel Prize awarded for its discovery in 1923 came into question years later.
