Sir Frederick Grant Banting was a Canadian medical scientist, physician, and painter best remembered for contributing to the discovery of insulin and for being the first person to use insulin on humans. Along with J. J. R Macleod, he received the Nobel Prize in Medicine in 1923 “for the discovery of insulin”. His valuable contribution helped to treat diabetes which used to be a dreaded fatal disease till then. He shared the Nobel Prize money with his colleague, Dr. Charles Best, whom he considered more deserving of the award than Macleod. Sir Banting graduated with a degree in medicine from the University of Toronto. He then joined the Canadian Army Medical Corps during World War I and served in France. After the war ended, he returned to Canada and worked as a medical practitioner in Ontario for some time. Later, he served as a Resident Surgeon at the Hospital for Sick Children in Toronto. He soon developed a keen interest in diabetes, and focused on extracting insulin from the pancreas of animals. Together with medical student Dr. Charles Best, he discovered a way to extract insulin and effectively treat diabetic patients. He received a lifetime annuity to work on his research from the Canadian government and was also knighted by King George V.
