Gertrud Schwend-Uexküll (born "Gertrud, Baronesse von Uexküll-Gyllenband": 17 May 1867 - 15 January 1901) was a well-born pioneer of girls' education. In 1899 she founded the "Mädchengymnasium" (secondary school for girls) in Stuttgart. It was the first such institution in the Kingdom of Württemberg and only the second anywhere in Germany.
