Gu Yanwu
In 1948, Wilhelm moved to the United States to take up a position as a professor of Chinese at the University of Washington, where he taught until he was forced to retire in 1971 due to eye problems that affected his vision and reading abilities. He authored dozens of articles and manuscripts, and was a key figure in establishing the Far Eastern and Russian Institute. A collection that includes documents relating to his life, photographs, and manuscripts of his scientific work on Gu Yanwu and the Yi Jing can be found in the German Exiles Archive of the German National Library.
