Query: Einstein of Sex, Foundation of the Gay Movement

Magnus Hirschfeld may not be a name well known in the U.S., but his studies and institute in Berlin advanced the gay movement as much as the Stonewall riots - and this was in 1943.This biopic of a great man is very well done by director Rosa Von Praunheim. The DVD offers a documentary in addition to the film and an interview with Von Praunheim.The film is in German, with English subtitles. There is quite a bit of male frontal nudity, but this is far from a pornographic film. It is a very well researched, well done biography of the man who coined the term - transvestite.Definitely recommend this film for anyone's library. It is an important record of our gay history
