On 27th July 1921, biochemist Frederick Banting and his team of researchers at the University of Toronto proved that the insulin hormone regulates blood sugar. Banting was also the first person to use insulin on humans.
For his seminal work, Frederick Banting, who was 32-years old then, was awarded the 1923 Nobel Prize in Physiology or Medicine, the youngest Nobel laureate in this field. Banting shared the prize money with Dr. Charles Best, his colleague.
Insulin was used to treat diabetes for the very first time on 11th January 1922.
