U.S. composer.
He studied at the Curtis Institute, then with the conductor Nadia Boulanger in Paris and the composer Arnold Schoenberg in Berlin. His best-known works were for the theatre: The Cradle Will Rock (1937), the circumstances of whose production by Orson Welles and John Houseman became legendary; the opera Regina (1949); and his English adaptation of Bertolt Brecht and Kurt Weill 's The Threepenny Opera (1952), which became a Broadway hit. He was working on a Metropolitan Opera commission for an opera about the Sacco-Vanzetti case when he was murdered.
