Barré Lyndon (pseudonym of Alfred Edgar) (1896 – 1972) was a British playwright and screenwriter. The pseudonym was presumably taken from the title character of Thackeray's novel. Born in London, he may be best remembered for three screenplays from the 1940s: The Lodger (1944), Hangover Square (1945) and The Man in Half Moon Street (1945). The latter was remade by Hammer Film Productions in 1959 as The Man Who Could Cheat Death. Lyndon began his writing career as a journalist, particularly about motor-racing, and short-story writer before becoming a playwright. His first play, The Amazing Dr. Clitterhouse, was made into an Edward G. Robinson film in 1939. After that success, Lyndon moved to Los Angeles, California, in 1941 to concentrate on writing for films full time.
