Christa Winsloe (23 December 1888 – 10 June 1944), formerly Baroness Christa von Hatvany-Deutsch, was a German-Hungarian novelist, playwright and sculptor, best known for her play Gestern und heute (known under several titles, see below), filmed in 1931 as Mädchen in Uniform and the 1958 remake. Winsloe was the first to write a play on female homosexuality in the Weimar Republic, yet without a "radical critique of the social discrimination of lesbian women."
