From 1921 to 1938, a pioneering liberal arts school for working women was held on the campus of Bryn Mawr College under the leadership of Hilda Worthington Smith. It graduated over 1,700 students from diverse racial, ethnic, and geographic backgrounds, and some of its alumnae became community, labor union, and public leaders. The school also served as a model for workers' and labor education programs at colleges and universities across the nation.
