Biography detail

Childhood And Early Life

Best was born on 27th February 1899 in West Pembroke, Canada. His father, Herbert Huestes Best, was a doctor an Luella Fisher was his mother. Best got admission for the Bachelor of Arts degree course in University of Toronto in 1916 but he interrupted his studies to join the Canadian army. He participated in World War I as part of the 2nd Canadian Tank Battalion of Canadian Army and resumed his studies after the war, rejoining the University of Toronto. In 1921, Best, at the age of 22, graduated in physiology and biochemistry. In the same year, he got an opportunity to work with Frederick Banting in his research to obtain a pancreatic extract of insulin so that it can be used for controlling diabetes mellitus. Though he was part of the research, he did not receive the Nobel Prize in 1923 for Physiology or Medicine along with Banting and J. J. R. Macleod because he had not completed his medical degree then. However, Banting voluntarily shared his portion of the prize with Best as an honor to his contribution to the research. Best had some personal interest in finding an effective treatment for diabetes for his aunt had died from diabetes in 1918. Best also discovered the vitamin ‘choline’ and the enzyme ‘histaminase’ and was one of the first to introduce anticoagulants to treat thrombosis. Best’s talents were not confined just to academics; he was a good athlete too. He was a professional basketball player and paid his fee with his earnings from basketball matches. However, his real calling being science, Best did not choose to become an athlete and opted for the research offer of Frederick Banting, turning down an offer to play in a high ranking team.

Co-discovery Of Insulin

Spring of 1921 became a turning point in Best’s life. It was during this time that Dr. Banting travelled to Toronto to visit J.J.R. Macleod who was working as the professor of physiology at the University of Toronto. Banting asked Macleod for permission to use his laboratory for his research work. Though skeptical initially, Macleod eventually agreed to allow Dr. Banting to use his laboratory and also allotted two medical students, Charles Best and Clark Noble, to assist in the research. However, Banting needed only one assistant and so, he flipped a coin to decide whom to pick. The coin favoured Best and he became Banting’s assistant for research. Banting was deeply impressed by Best’s efforts in the research and gave him majority of the credit for the discovery. Banting also shared half of His Nobel Prize remuneration with Best.

Career Post Discovery

After the successful participation in the discovery of insulin, Best joined as a professor of Physiology in the University of Toronto in 1929, succeeding Macleod. He played an instrumental role in establishing a Canadian program for securing and using dried human blood serum. He then became an adviser to the United Nations World Health Organization’s ‘Medical Research Committee’.
