Frederick Banting realized that this procedure would destroy the trypsin-secreting cells but not the insulin. Once the trypsin-secreting cells had died, insulin could be extracted from the islets of Langerhans. Banting discussed this approach with J. J. R. Macleod, Professor of Physiology at the University of Toronto. Macleod provided experimental facilities and the assistance of one of his students, Charles Best. Banting and Best, with the assistance of biochemist James Collip, began the production of insulin by this means. As the experiments proceeded, the required quantities could no longer be obtained by performing surgery on living dogs. In November 1921, Banting hit
Frederick Banting A "Flame of Hope" was lit by Her Majesty Queen Elizabeth the Queen Mother in 1989 as a tribute to Dr. Frederick Grant Banting and all the people that have lost their lives to diabetes. The flame will remain lit until there is a cure for diabetes. When a cure is found, the flame will be extinguished by the researchers who discover the cure. The flame is located at Sir Frederick Banting Square in London, Ontario, Canada beside the Banting House National Historic Site of Canada. A time capsule was buried in the Sir Frederick Banting Square in 1991 to
