Born in Beckenham in 1907, the late Sydney Box (1907-83) was a writer and film producer, producing such classics as The Seventh Veil (1945, which won him a best screenplay Oscar), Holiday Camp and Quartet . His film company Verity Films produced over 100 propaganda shorts for the government and the services during the Second World War. Managing director of Gainsborough Pictures (1946-49), he became an independent producer in the 1950s, forming Sydney Box Associates. Most of his screenplays were written in collaboration with his late wife, Muriel. Their collaborative work was published under the pseudonym "Evelyn August." The Muriel and Sydney Box Collection is located at the British Film Institute.
