Profile

In the 1920s, the Institute for Sexual Research in Berlin was a haven for queer people, many of whom came to the institute seeking to express their identities without fear of being imprisoned. This undated photo depicts a costume party at the institute; its founder, Magnus Hirschfeld (second from right, in glasses), can be seen holding hands with his partner, Karl Giese (center).
