Winner of the Berkshire Conference of Women Historians Prize In volume one of this landmark study, focusing on developments up to 1940, Margaret Rossiter describes the activities and personalities of the numerous women scientists—astronomers, chemists, biologists, and psychologists—who overcame extraordinary obstacles to contribute to the growth of American science. This remarkable history recounts women's efforts to establish themselves as members of the scientific community and examines the forces that inhibited their active and visible participation in the sciences.
