Christopher William Bradshaw Isherwood 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 into a film directed by Tom Ford in 2009; and Christopher and His Kind (1976), a memoir which "carried him into the heart of the Gay Liberation movement".

With W.H. Auden, he wrote three plays—The Dog Beneath the Skin (1932), The Ascent of F6 (1936), and On the Frontier (1938). Isherwood tells the story in his first autobiography, Lions and Shadows.

After Isherwood wrote joke answers on his second-year exams, Cambridge University in 1925 asked him to leave. He briefly attended medical school and progressed with his first two novels, All the Conspirators (1928) and The Memorial (1932).
