Franz Boas (July 9, 1858 - December 21, 1942) was a German American anthropologist and a pioneer of modern anthropology who has been called the "Father of American Anthropology." Like many such pioneers, he trained in other disciplines; he received his doctorate in physics, and did post-doctoral work in geography. He is famed for applying the scientific method to the study of human cultures and societies, a field, which was previously based on the formulation of grand theories around anecdotal knowledge.
