The discovery of a life-saving treatment for diabetes at the University of Toronto in 1921 made headlines worldwide and was formally acknowledged just two years later when the Nobel Prize for Medicine was awarded to two of the team members.

An illustrated timeline of the most significant events that led to the discovery and initial dissemination of insulin is provided here, and the full story with thousands of the original archival documents is available through the UTL's digital special collection entitled The Discovery and Development of Insulin.

A digital exhibition to celebrate the 100th anniversary of the discovery of Insulin is also available.
