From the 1920s until 1949, foreign adult educators (mostly women) in the Shanghai YWCA worked to foster labor unrest and build a better world. Many started out as liberal Christians but ended up supporting Chairman Mao. They used street theater, mass singing, games, pageants, structured exercises, and "bible classes," where learners read Communist literature. Their extraordinary efforts are largely unrecognized because many self-identified as homosexual and Communist. This study involved interviews and a close reading of English- and Chinese-language materials. Its purpose was to document revolutionary adult education (mostly for young women) in the Shanghai silk filatures (1920 to 1949) and to create an understanding of the work of foreigners such as Rewi Alley and Maud Russell and visiting luminaries such as John Dewey and R. H. Tawney. In China, there is a tendency to ignore the past. Yet 21st century adult education could be improved by understanding adult education in 1920s, 1930s, and 1940s Shanghai.
