Franz Weidenreich

Born 7 Jun 1873; died 11 Jul 1948 at age 75.German anatomist and physical anthropologist whose reconstruction of prehistoric human remains and work on Peking man (then called Sinanthropus pekinensis) and other hominids brought him to preeminence in the study of human evolution. A Jew, Weidenreich fled Nazi Germany to take a position in Beijing. He worked with Teilhard de Chardin on the Zhoukoudian fossils (at the Cave of Peking Man), next fleeing the Japanese during WW II. His "multiregional" hypothesis of human origins (i.e., that human racial lineages date back to the early Pleistocene) became influential and is still widely debated, but at first it was misinterpreted as arguing that there was no genetic continuity between human races.
