Marvin David Levy (born August 2, 1932, New Jersey) is an American composer. He is perhaps best known for his opera Mourning Becomes Electra which was given its world premiere at the Metropolitan Opera in 1967. Although deemed a failure at the time, the work was revived in 1998 in a revised version by the composer to a triumphant success at the Lyric Opera of Chicago. The New York City Opera and the Seattle Opera staged the work in 2003. The Florida Grand Opera will stage it in November 2013 in Miami and Ft. Lauderdale, FL.
