1921 - Canadian researchers produce effective insulin
Frederick Banting (photo), a young surgeon, assisted by Charles Best, a medical student, successfully extracts effective insulin from a canine pancreas at the University of Toronto in Canada. John Macleod, the head of the Department of Physiology, assigns biochemist James Collip to work on the project. Collip’s method leads to the first person with diabetes being treated with bovine insulin in January 1922. As a result of this breakthrough, insulin begins to be manufactured in several places globally.
