Title: Dalton Trumbo
Passage: James Dalton Trumbo (December 9, 1905 – September 10, 1976) was an American screenwriter and novelist, who scripted films including "Roman Holiday", "Exodus", "Spartacus", and "Thirty Seconds Over Tokyo".  One of the Hollywood Ten, he refused to testify before the House Un-American Activities Committee (HUAC) in 1947 during the committee's investigation of Communist influences in the motion picture industry.  He was subsequently blacklisted by that industry.  He continued working clandestinely, producing work under other authors' names.  His uncredited work won two Academy Awards; the one for "Roman Holiday" (1953) was given to a front writer, and the one for "The Brave One" (1956) was awarded to a pseudonym.  The public crediting of him as the writer of both "Exodus" and "Spartacus" in 1960 marked the end of the Hollywood Blacklist.  His earlier achievements were eventually credited to him by the Writers Guild, 60 years after the fact.
