Duncan was wildly unconventional. A bisexual who had two children but did not marry either of their fathers, she became a communist, and boasted about it. She went to the Soviet Union in 1922, but left in less than two years. At different times she lived in Paris, London and other European cities. She started dance schools in Moscow, Berlin and Paris. The schools did not last long, but Duncan had admirers who have continued her influence to the present day.
