Charles Best (medical scientist) the pancreatic extract and monitoring glucose levels, MacLeod assigned the biochemist James Collip to the team. In January 1922, while Collip was working on insulin purification, Best and Banting administered prematurely their pancreatic extracts to 14-year-old Leonard Thompson, who suffered a severe allergic reaction. Eventually, Collip succeeded in preparing insulin in a more pure, usable form. Banting, Best and Collip shared the patent for insulin, which they sold to the University of Toronto for one dollar. In 1923, the Nobel Prize Committee honoured Banting and J. J. R. Macleod with the Nobel Prize in Medicine for the discovery of insulin,
Banting House headed during the Second World War, and an entire gallery filled with artwork done by Banting. Adjacent to the museum is Sir Frederick G. Banting Square, a garden with several information plaques, and three main attractions. Two of the attractions, a full-sized sculpture of Banting writing his life-altering idea down, and the Flame of Hope, were unveiled by Her Majesty Queen Elizabeth The Queen Mother. The Flame of Hope, symbolizing the hope for a final cure for diabetes, was kindled by Her Majesty during her visit. The third attraction is the globe sculpture, which was added more recently in 2010.
