Stefan Wolpe (August 25, 1902 – April 4, 1972) was a German-born composer.
Wolpe was born in Berlin. He attended the Klindworth-Scharwenka Conservatory from the age of fourteen, and the Berlin Hochschule für Musik in 1920–21. He studied composition under Franz Schreker and was also a pupil of Ferruccio Busoni. He also studied at the Bauhaus and met some of the dadaists, setting Kurt Schwitters's poem An Anna Blume to music.
In 1928, Wolpe's first opera, Zeus und Elida, premiered in Berlin. This soon was followed by two more operas in 1929, Schöne Geschichten and Anna Blume. The music Wolpe was writing between 1929 and 1933 was dissonant, using Arnold Schoenberg's twelve-tone technique. However, possibly influenced by Paul Hindemith's concept of Gebrauchsmusik (music that serves a social function) and, as an avid socialist, he wrote a number of pieces for worker's unions and communist theatre groups. For these he made his style more accessible, incorporating elements of jazz and popular music. His songs became popular, rivaling those of Hanns Eisler.
