Hirschfeld, whose life was dedicated to social progress for people who were transsexual, transvestite and homosexual, formed the Institut für Sexualwissenschaft (Institute for Sexology) in 1919. The institute conducted an enormous amount of research, saw thousands of transgender and homosexual clients at consultations, and championed a broad range of sexual reforms including sex education, contraception and women's rights. However, the gains made in Germany would soon be drastically reversed with the rise of Nazism, and the institute and its library were destroyed in 1933. The Swiss journal Der Kreis was the only part of the movement to continue through the Nazi era.
