Karen Pastorello's pathbreaking biography of Bessie Abramowitz Hillman places this remarkable labor leader and Progressive Era activist at the center of the founding of the Amalgamated Clothing Workers of America. Bridging the gap between Progressive social feminism and the labor feminists of the post-World War II period, Hillman worked to end race and class injustice and improve the quality of life for working women, even as she was overshadowed by her husband, union leader Sidney Hillman. Interweaving Hillman's experiences as an Eastern European Jewish immigrant with a rich historical account of the founding and development of a key garment union, Pastorello reveals the prominent role of women labor activists in both the workplace and union leadership.
