The Bryn Mawr Summer School for Women Workers in Industry (1921–1938) was a residential summer school program that brought approximately 100 young working women—mostly factory workers with minimal education—to the Bryn Mawr College campus, in Bryn Mawr, Pennsylvania, each year for eight weeks of liberal arts study. As part of the workers' education movement of the 1920s and 30s, the experimental program was unique in several ways. It was the first program of its kind for women in the United States; it was conceived, directed, and largely taught by women; and it was hosted by a women's college.
