James Dalton Trumbo was born in 1905, the son of Orus Trumbo and Maud Tillery. He married Cleo Beth Fincher, 13 Mar 1938.
Dalton was a successful screenwriter and novelist until 1947, when he was one of several writers and actors, summoned to testify before the House Un-American Activities Committee about their alleged involvement with the Communist Party. Because of his refusal to testify, he spent 10 months in prison at Ashland, Kentucky. The motion picture industry “Blacklist” left him unemployed, after his prison release, so he moved his family to Mexico City, along with other Blacklisted writers, for a short time. He survived, writing scripts under pseudonyms and would win an Academy Award under the name 'Robert Rich' for the movie "The Brave One." Not until after 1960 was he able to use his own name on scripts he was writing.He passed away in 1976
