This intellectual biography of Lev Shternberg (1861-1927) illuminates the development of professional anthropology in late imperial and early Soviet Russia. Shortly after the formation of the Soviet Union the government initiated a detailed ethnographic survey of the country's peoples. Lev Shternberg, who as a political exile during the late tsarist period had conducted ethnographic research in northeastern Siberia, was one of the anthropologists who directed this survey and consequently played a major role in influencing the professionalization of anthropology in the Soviet Union.
