John Michael Terence Wellesley Denison CBE (1 November 1915 – 22 July 1998) was an English actor. Denison was born in Doncaster, West Riding of Yorkshire in 1915. He was brought up by his aunt and uncle from the age of three weeks, following the death of his mother and his estrangement from his father. He was educated at Harrow where he took part in school productions. It was while at Magdalen College, Oxford University, studying modern languages that he met John Gielgud and decided to take up acting seriously. After graduating, he attended the Webber Douglas Academy of Dramatic Art, where he met Dulcie Gray, a fellow student, who later became his wife in 1939 and his acting partner. They appeared in over 100 West End productions, together in some 28 plays in London and countless tours of Britain and elsewhere. They also appeared together in several films. Their intertwined professional lives reached their pinnacle in 1996 with their first appearance together on Broadway, in the Peter Hall production of Oscar Wilde's An Ideal Husband. Their last appearance together was in Curtain Up, an evening of reminiscences at the Jermyn Street Theatre in London, shortly before he died.
