Friedrich Radszuweit was a German manager, publisher, and author and LGBT activist, who was of major importance to the first homosexual movement. In 1923, Radszuweit became president of the organisation Bund für Menschenrecht E.V. (BfM), which worked for the rights of gay people and for the repeal of Paragraph 175 in Germany. He started his own publishing company and published the monthly magazine *Zeitschrift für Menschenrecht* from 1923 to 1933. He went on to publish such magazines as *Die Insel, Magazin der Einsamen* (1926–1931), the transvestite magazine *Das 3. Geschlecht* (five issues: 1930–1932), and the lesbian magazine *Die Freundin, Wochenschrift für ideale Frauenfreundschaft* (1924-1933). The company also published several LGBT books and homoerotic graphics and produced the first gramophone record with homosexual themes, *Bubi laß uns Freunde sein* by Bruno Balz and Erwin Neuber. Radszuweit himself wrote the novels *Männer zu verkaufen*, *Ledige Frauen*, *Die Symphonie des Eros* and *Paul Tritzkis Lebensweg*. In 1927, he produced a flyer for the members of the Reichstag advocating reform of § 175.
