After the war, Krader returned to the US and studied linguistics (1945–1947) at
Columbia University with
Roman Jakobson and
André Martinet. During this time, he developed an interpretation of
human evolution which resulted in him leaving his focus on philosophy and commencing an intensive study of the
Eurasian nomads; becoming a fellow of the Far Eastern Institute at the
University of Washington in Seattle. His new research interests probably also owed something to his meeting with
Karl Wittfogel in 1947, whom he helped with research and Russian translations and also to his contact with
Karl Korsch. Krader was Wittfogel's assistant from 1948 to 1951. In 1952, Krader taught linguistics as a Fellow of the Russian Research Center at
Harvard and married his wife Dr.
Barbara Lattimer in 1953. In 1954 he graduated at Harvard with a PhD on "Kinship Systems of the Altaic-speaking peoples of the Asian Steppes" (supervised by
Clyde Kluckhohn). From 1953 to 1956, he was appointed research associate at the Bureau of Social Science Research at the
American University of Washington, D.C., in the area of Central Asian Studies. In 1956–1958 he became professor in anthropology and director of the Nomads Program at the
Syracuse University and leader of the China Population Program at the
United States Census Bureau. From 1957 to 1959, Krader became president of the Anthropological Society of Washington. From 1958 to 1963, he taught as ordinary professor at the American University in Washington, D.C., as well as being representative for ethnology and anthropology at the Social Science Council and Human Science Council of
UNESCO, leader of the anthropological section of the sociology and anthropology department at CCNY, and chairman of the sociology and anthropology department at the
University of Waterloo in Canada. In 1962, Krader traveled for the first time to outer
Mongolia. From 1963 to 1968 Krader received finance for his research project on the Evolution of the State and Nomadism, from the
National Science Foundation. From 1964 to 1978, Krader became secretary-general of the
IUAES. For his study of the roots of the
theory of evolution in the 19th century, he received support from the
International Institute of Social History (Amsterdam) during 1963–1975. From 1970 to 1972, Krader was professor at the University of Waterloo but in 1972 joined the Institute for Ethnology at the
Free University of Berlin, where he became director until 1982. From 1989 until his death, Krader produced 156 manuscripts including works on Labour and Value: a Theory of the Russian Revolution, Mathematical Logic, a Critique of Evolution, Linguistics and other topics. It is intended that some of this material will be published via a research project at
McMaster University with the aid of an endowment. ==Quotation==
