(Suggest an Edit or Addition)

According to Wikipedia, Charles Herbert Best , was an American-Canadian medical scientist and one of the co-discoverers of insulin. Personal life Born in West Pembroke, Maine, on February 27, 1899, to Luella Fisher and Herbert Huestis Best, a Canadian-born physician from Nova Scotia. His father, Herbert Best, was a doctor in a small Maine town with a limited economy based mostly on sardine-packing. His mother, Lulu Newcomb, later Lulu Best, who sang soprano, accompanying herself on organ and piano, was in demand as a performer at funerals and weddings. Best grew up in Pembroke before going to Toronto, Ontario, to study medicine in 1915.
