The Scientific-Humanitarian Committee was founded in Berlin on the 14th or 15 May 1897, to campaign for social recognition of homosexual and transgender men and women, and against their legal persecution. It was the first such organisation in history. It produced the Jahrbuch für sexuelle Zwischenstufen (Yearbook for Intermediate Sexual Types). This, as well as reporting the committee's activities, carried articles of scientific, polemical and literary natures. It was publish regularly from 1899 to 1923 (sometimes even quarterly) and more sporadically until 1933.
