In 1921 the Medical Court of Honour of the County Brandenburg and Berlin procured an expert opinion by the well-known psychiatrist Emil Kraepelin on the first sex education film "Anders als die Andern". The Berlin sexologist Magnus Hirschfeld had launched the film in 1919 to bring his scientific targets of abolition of section 175 StGB and the liberalization of sexual morality to a greater public. Kraepelin succeeded in banning the film because of its subject being a threat to population policy in post World War I Germany.
