Researchers Frederick G. Banting and John Macleod were jointly awarded the Nobel Prize in 1923 for their partnership in the discovery of insulin. After receiving the prize, Banting publicly contended that Macleod, the head of their laboratory, had been more of a hindrance in the research than a help. For his part, Macleod, in speeches about the work that led to the discovery, routinely failed to mention that he had had a research partner.
