The aim of this article is to present the figure and postulates of Louise Otto‑Peters, one of the most important women’s rights activists in Germany. In the 19th century she courageously fought against social injustice and postulated a number of social and legal changes. In her treatise Das Recht der Frauen auf Erwerb (Women’s Right to Employment) she proclaimed the need to introduce equality, to fundamentally change the education system, and to expand women’s earning opportunities. She sharply criticized society’s behavior. Louise Otto‑Peters also proclaimed the neces­sity to improve the professional situation of women, which would guarantee their independence and thus the development of their own personalities.
