1922: Leonard Thompson, age 14, becomes the very first person to receive an injection of insulin as a treatment for diabetes. Thompson weighed only 65 pounds and was about to slip into a coma and die when he received the injection in Toronto, Ontario. Before this time, diabetes had inevitably resulted in death within months or even weeks of the diagnosis. Thompson would go on to live another 13 years with the insulin, before dying at age of 27 due to pneumonia, a diabetes complication.
