Michael Chekhov established the Chekhov Theatre Studio at Dartington Hall in Devonshire, England, assisted by Deirdre Hurst du Prey, an acting student who helped him learn English. In 1939 the war forced the studio to move overseas to Ridgefield, Connecticut. The group eventually disbanded in 1942, when many of its actors were drafted into the armed forces. After Chekhov moved to California and continued to teach, lecture, and act in motion pictures, Deirdre Hurst du Prey edited two additional books based on his ideas. She also compiled the book "The actor in the theatre: A collection of Michael Chekhov's unpublished notes and manuscripts on the art of acting and the theatre."
