Historian and U of T professor emeritus Michael Bliss said in his book, The Discovery of Insulin:
The discovery of insulin at the University of Toronto in 1921 – 22 was one of the most dramatic events in the history of the treatment of disease. Insulin’s impact was so sensational because of the incredible effect it had on diabetic patients. Those who watched the first starved, sometimes comatose, diabetics receive insulin and return to life saw one of the genuine miracles of modern medicine. They were present at the closest approach to the resurrection of the body that our secular society can achieve, and at the discovery of what has become the elixir of life for millions of human beings around the world.
