Christopher William Bradshaw Isherwood (26 August 1904 – 4 January 1986) was an Anglo-American novelist, playwright, screenwriter, autobiographer, and diarist. His best-known works include Goodbye to Berlin (1939), a semi-autobiographical novel which inspired the musical Cabaret (1966); A Single Man (1964), adapted as a film by Tom Ford in 2009; and Christopher and His Kind (1976), a memoir which "carried him into the heart of the Gay Liberation movement".
