Karl Heinrich Ulrichs (1825–1895): A 200-Year Jubilee with Pitfalls.

For the opponents of the sexual reform movement, he was the father of all evil; for the proponents of the decriminalization of same-sex desire, he paved the way for objective research. With the term "Urning", he gave homosexuals an anthropological dignity. The Hanoverian lawyer Karl Heinrich Ulrichs (1825–1895) was notorious during his lifetime and at times esteemed after his death, but it was not until the 1990s that he became the secret hero of sexual emancipation and sexual history/historiography. Streets and squares were named after him, but his life's work was also often instrumentalized. [ABSTRACT FROM AUTHOR]
