About this place Institut für Sexualwissenschaft (site)

The Institut für Sexualwissenschaft was the world's first academic sexology institute, founded on 6 July 1919 by physician Magnus Hirschfeld (1868-1935) in a former palace at In den Zelten 9-10 on the northern edge of Tiergarten. For fourteen years it operated as a combined research library, medical clinic, counselling service, and public archive, with a queer marriage and law-reform advocacy operation attached. Hirschfeld's Institut was the epicentre of an international queer scientific network. It housed a library of some 20,000 volumes, an archive of photographs and life histories from more than 30,000 subjects, an operating theatre performing what would today be called gender-affirming surgery (the first documented modern vaginoplasty was performed here in 1931 on Dora Richter), and a hostel for trans and homosexual staff and refugees. Hirschfeld was Jewish, homosexual and socialist — three characteristics that made the Institut the earliest Nazi target of any German medical institution. On 6 May 1933 the Deutsche Studentenschaft raided and looted the Institut. Four days later, on 10 May, its library — some 20,000 volumes plus the entire life-history archive — was among the books burned publicly at Bebelplatz. Hirschfeld, on a world tour when the raid happened, never returned to Germany and died in Nice in 1935. The original building was destroyed in Allied bombing in 1944. The Kongresshalle (now Haus der Kulturen der Welt) stands on part of the site; the actual Institut plot is now parkland. A large information stele installed by the Magnus-Hirschfeld-Gesellschaft in 1994 stands at the corner where the building stood; a second memorial by artist Georg Kolbe was added in 2011. Free, open 24/7 as public parkland. Combine with the Tiergarten Homosexuals Memorial (750 m south) for a longer walk.

A beautiful memorial for Magnus Hirschfeld, with a scannable QR code with more information to read or listen to on the website. A great visit for queer and trans tourists or history buffs.

A memorial plaque for a very courageous man and scientist, Magnus Hirschfeld, whose work and research remain visionary to this day.

Wow, the monument has an audio tour that you can read or listen to via QR code. On the website, you can also find out more about hirschfel and more of his people around like Karl Giese, Dora Richter, Christopher Isherwood, Lili Elbe, Fritz Flato, and others.

A monument commemorating the sexology institute, a precursor to LGBT rights in the Weimar Republic, which was later attacked and occupied by the Nazis. The monument is divided between the two banks of the river.

Lovely place and good to see it remembered.

One of the many places in Berlin where absolutely nothing recalls its grand past—until 1933, the world's first institute for sexology stood here; all gone. Only a commemorative plaque now serves as a reminder.
