Colin Wilson wrote his play The Death of God in 1956-57 in response to a request from George Devine (1910-66), the director of the English Stage Company (founded 1955) at the Royal Court Theatre in London, which staged such plays as Look Back in Anger (1956) by John Osborne (1929-94) and Roots (1958) by Sir Arnold Wesker (b. 1932). Wilson’s play was rejected and has never been performed, but was eventually published in 2008.
