Marvin David Levy
 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 and the Florida Grand Opera staged the opera in 2013.
