Bertha Pappenheim left her mark on the history of psychoanalysis as a patient of Josef Breuer. Her case history was related under the pseudonym "Anna O." in the "Studies on Hysteria" (1895) by Sigmund Freud and Josef Breuer. She is considered the most important representative of the Jewish women's movement, who campaigned for improving the living conditions of Jewish women and girls and fought against international white slavery. She founded the Jewish Women's League (Jüdischer Frauenbund) in 1904 and published countless tracts about the situation of Jewish women and the role of the woman in Judaism. In Neu-Isenburg near Frankfurt am Main she opened and directed the Jewish Women's League Home, in which pregnant women, single mothers and their children found refuge and support.
