Yep. The Institut für Sexualwissenschaft (Institute for Sexual Science) was founded by ✡Magnus Hirschfeld✡, performing the first hormone “treatments” and “reconstructive” surgeries for the mentally ill who believed themselves the wrong sex. The Institute also published books to propagandize this “way of life.” Books such as *Sittengeschichte des Lasters* (History of Perversions), *Sittengeschichte des Schamlosigkeit* (History of Shamelessness), *Bilderlexikon der Erotic* (Picture Lexicon of Eroticism), *Sittengischichte des Geheime und Verbotene* (History of the Secret and the Forbidden). “Scientific” documents published by the Institute included *Aphrodisiacs*, *Prostitution*, *Sexual Catastrophes*, *Sexual Pathology*, and *The Perverted*.
