1922 – Leonard Thompson becomes the first person to be injected with insulin
Leonard Thompson received his first injection in Toronto, Ontario, on this day in 1922, at 14 years of age. The first injection had an apparent impurity which was the likely cause for the allergic reaction he displayed. After a refined process was developed by James Collip to improve the canine pancreas extract, the second dosage was successfully delivered to the young patient twelve days after the first. Thompson showed signs of improved health and went on to live 13 more years taking doses of insulin, eventually dying of pneumonia at age 26. Until insulin was made clinically available, a diagnosis of Type 1 diabetes was a death sentence, more or less quickly (usually within months, and frequently within weeks or days).
