Margarete Rosenberg née Quednau (1910–1985) was a German tram conductor who was arrested in September 1940 in Berlin. She was accused of seriously compromising the Berlin Transport Authority (BVG) by failing to report for work after going out drinking with her female colleagues. Although she admitted to having sexual relationships, she was not accused of lesbianism. Together with her colleague Elli Smula (1914–1943) she was sent to the Ravensbrück Concentration Camp the following November where she was nevertheless listed and treated as a lesbian. She was among those who survived the ordeal, being rescued by the Americans in April 1945 after four and a half years of imprisonment.[1][2][3]
