More than just the story of Charles Bests discovery of insulin, this is the tale of an extraordinary couple, told through diaries, scrapbooks, and photographs.

Although Charles Best is known for discovering insulin, the story of his life neither begins nor ends with that one moment. Not only did he make many other discoveries, he was also one half of an extraordinary couple who, during their almost sixty years together, were involved in many of the significant events of the twentieth century. Margaret & Charley is the story of these two people from their beginnings on the east coast at the turn of the century through the years that followed. Through diaries, scrapbooks, photograph albums, and other documentation, the details of their lives are shared with the reader.
