Scientific-Humanitarian Committee

The Scientific-Humanitarian Committee (German: Wissenschaftlich-humanitäres Komitee, WhK) was a transnational advocacy group and civil rights organization founded by Magnus Hirschfeld in Berlin in May 1897, to campaign for the legal rights and social recognition of lesbian, gay, bisexual, and transgender (LGBT) people, and against their institutionalized discrimination and persecution in Western societies. It was the first LGBT rights organization in history.
