Fully five decades before Olympe de Gouges, Mary Woll–stonecraft, and Theodor Gottlieb von Hippel spoke out for the equality of men and women, Dorothea Christiane Leporin, Germany's first female medical doctor, challenged the readers of her Thorough Investigation of the Causes which Prevent the Female Sex from Studying to free themselves from the idea that all women are destined to serve husband, house, and children. As she put it: “If one admits that the female sex is capable of learning, then one must also admit that it has received a calling to go with it.” She reached this conclusion by accepting the assumption that men and women are equally suited for intellectual endeavors and then questioning all real and fictitious obstacles that were placed in the way of female study. Like all her known contemporaries, Leporin did not want to press all women into advanced study, which according to her would cause disorder, but she pleaded eloquently for the removal of prejudices and obstacles to talent.
