Frederick Banting was a Canadian physician and medical scientist best known for his role in discovering insulin, which transformed diabetes treatment. Born on November 14, 1891, in Alliston, Ontario, Banting was initially educated in medicine at the University of Toronto. His groundbreaking research began when he theorized that a hormone from the pancreas could help manage diabetes, which led him to collaborate with other scientists for experimental work. In 1921, Banting and his assistant Charles Best successfully isolated insulin, leading to its development as a lifesaving treatment for diabetes. This achievement not only earned them global recognition but also garnered Banting the Nobel Prize in Physiology or Medicine in 1923, which he shared with J.J.R. Macleod. Banting's contributions extended beyond insulin. He continued to explore various medical frontiers until his untimely death in 1941. His legacy endures through the millions of lives improved by insulin therapy, and he remains a pivotal figure in the history of medicine.
