Christopher Isherwood was born in 1904 and moved to America where he took up formal citizenship in 1946. His many famous works include Mr. Norris Changes Trains and Goodbye to Berlin.
Isherwood taught English in Berlin from 1929 to 1933 and in Goodbye to Berlin wrote a semi-autobiographical record of his experiences. It remains the archetypal sketch of prewar Berlin, its bars and its boys, and introduces the immortal Sally Bowles. Before the dawn of Cabaret, Goodbye to Berlin was adapted into a play by John van Druten as I Am a Camera in 1951. (Kirkus UK)
