In 1922, Lenya was seen by her future husband, German-Jewish composer
Kurt Weill, during an audition for his first stage score
Zaubernacht, but because of his position behind the piano, she did not see him. She was cast, but owing to her loyalty to her voice coach, she declined the role. She accepted the part of Jenny in the first performance of
The Threepenny Opera (
Die Dreigroschenoper) in 1928, and the part became her breakthrough role. During the last years of the
Weimar Republic, she was busy in film and theatre, and especially in
Brecht-Weill plays. She made several recordings of Weill's songs. With the rise of
Nazism in Germany, many artists were not appreciated, and although not Jewish, she left the country, having become estranged from Weill. (They would later divorce and get married again.) In March 1933, she moved to Paris, where she sang the leading part in Brecht-Weill's "sung ballet",
The Seven Deadly Sins. Lenya and Weill settled in New York City on 10 September 1935. During the summer of 1936, Weill, Lenya,
Paul Green, and
Cheryl Crawford rented a house at 277 Trumbull Avenue in
Nichols, Connecticut, about 2 miles (3.2 km) from
Pine Brook Country Club, the summer rehearsal headquarters of the
Group Theatre. Here, Green and Weill wrote the script and music for the controversial Broadway play
Johnny Johnson, which was titled after the most frequently occurring name on the American casualty list of World War I. During this period, Lenya had a love affair with playwright Paul Green. During World War II, Lenya did a number of stage performances, recordings, and radio performances, including for the
Voice of America. After a badly received part in her husband's
musical The Firebrand of Florence in 1945 in New York, she withdrew from the stage. After Weill's death in 1950, she was coaxed back to the stage. She appeared on
Broadway in
Barefoot in Athens and married editor
George Davis. ==Late career==
