> This comes from History.com
> At Toronto General Hospital, 14-year-old Canadian Leonard Thompson becomes 
> the first person to receive an insulin injection as treatment for 
> diabetes. Diabetes has been recognized as a distinct medical condition for 
> more than 3,000 years, but its exact cause was a mystery until the 20th 
> century. By the early 1920s, many researchers strongly suspected that 
> diabetes was caused by a malfunction in the digestive system related to 
> the pancreas gland, a small organ that sits on top of the liver. At that 
> time, the only way to treat the fatal disease was through a diet low in 
> carbohydrates and sugar and high in fat and protein. Instead of dying 
> shortly after diagnosis, this diet allowed diabetics to live--for about a 
> year.
> A breakthrough came at the University of Toronto in the summer of 1921, 
> when Canadians Frederick Banting and Charles Best successfully isolated 
> insulin from canine test subjects, produced diabetic symptoms in the 
> animals, and then began a program of insulin injections that returned the 
> dogs to normalcy. On November 14, the discovery was announced to the 
> world.
> Two months later, with the support of J.J.R. MacLeod of the University of 
> Toronto, the two scientists began preparations for an insulin treatment of 
> a human subject. Enlisting the aid of biochemist J.B. Collip, they were 
> able to extract a reasonably pure formula of insulin from the pancreas of 
> cattle from slaughterhouses and used it to treat Leonard Thompson. The 
> diabetic teenager improved dramatically, and the University of Toronto 
> immediately gave pharmaceutical companies license to produce insulin, free 
> of royalties. By 1923, insulin had become widely available, saving 
> countless lives around the world, and Banting and Macleod were awarded the 
> Nobel Prize in Medicine.
