Magnus Hirschfeld (14 May 1868 – 14 May 1935) was a German physician and sexologist. Hirschfeld was educated in philosophy, philology and medicine. An outspoken advocate for sexual minorities, Hirschfeld founded the Scientific-Humanitarian Committee and World League for Sexual Reform. He based his practice in Berlin-Charlottenburg during the Weimar period. Historian Dustin Goltz characterized the committee as having carried out "the first advocacy for homosexual and transgender rights". He is regarded as one of the most influential sexologists of the twentieth century.
