Gerritsen Women's History Collection of Aletta H. Jacobs This link opens in a new windowIn the late 1800's, Dutch physician and feminist Aletta Jacobs and her husband C.V. Gerritsen began collecting books, pamphlets and periodicals reflecting the evolution of a feminist consciousness and the movement for women's rights. By the time their successors finished their work in 1945, the Gerritsen Collection was the greatest single source for the study of women's history in the world, with more than 4,700 books, pamphlets and journals spanning four centuries and 15 languages.
