Ales Hrdlicka

Died 5 Sep 1943 at age 74 (born 29 Mar 1869).Czech anthropologist known for his studies of Neanderthal man and his theory of the migration of American Indians from Asia. He worked gratis as a field anthropologist (1899-1903) under Fredric Ward Putnam, in four intense anthropometric studies of the Indians of the American Southwest and northern Mexico. In 1903, Hrdlicka joined the Smithsonian Institute, where during the next forty years, he compiled the most complete collection of human bone material in the world. He was the one of the first scientists to argue the Americans originated in Asia and came across the Bering Strait, and participated in numerous archeological expeditions which contributed a great amount of information and physical evidence.
