Lion was born in Constantinople to a Jewish family during Ottoman rule. She moved to Berlin after World War I with her father to join the school of Russian ballet. She was a successful chanteuse, parodist, cabaret singer, and actress, best known for her role as Pirate Jenny in director G. W. Pabst's 1931 French-language adaptation of Bertolt Brecht and Kurt Weill's Threepenny Opera (Die Dreigroschenoper). In 1928, Lion and Dietrich sang a famous duet, "Wenn die beste Freundin mit der besten Freundin", a song which allegedly had lesbian overtones and which became a hit in Weimar Berlin prior to Dietrich's departure for Hollywood.[citation needed]
