Lynn Thorndike (1882-1965), Thorndike taught at Columbia between 1924 and 1950. In this time he played a pioneering role in no less than three fields: medieval and intellectual history, and, above all the history of science. Thorndike wrote pioneering surveys of medieval Europe, and of world history, in addition to his classic eight-volume work on the history of magic and experimental science. He was a founder of the History of Science Society and served as its fifth president. Thorndike also served as president of the American Historical Association in 1955.
