Sir Arthur John Gielgud, OM, CH (14 April 1904 – 21 May 2000), was an English actor and theatre director whose career spanned eight decades. With Ralph Richardson and Laurence Olivier, he was one of the trinity of actors who dominated the British stage for much of the 20th century. A member of the Terry family theatrical dynasty, he gained his first paid acting work as a junior member of his cousin Phyllis Neilson-Terry's company in 1922. After studying at the Royal Academy of Dramatic Art he worked in repertory theatre and in the West End before establishing himself at the Old Vic as an exponent of Shakespeare in 1929–31.
During the 1930s Gielgud was a stage star in the West End and on Broadway, appearing in new works and classics. He began a parallel career as a director, and set up his own company at the Queen's Theatre, London. He was regarded by many as the finest Hamlet of his era, and was also known for high comedy roles such as John Worthing in The Importance of Being Earnest. In the 1950s Gielgud feared that his career was threatened when he was convicted and fined for a homosexual offence, but his colleagues and the public supported him loyally. When avant-garde plays began to supersede traditional West End productions in the later 1950s he found no new suitable stage roles, and for several years he was best known in the theatre for his one-man Shakespeare show, The Ages of Man. From the late 1960s he found new plays that suited him, by authors including Alan Bennett, David Storey and Harold Pinter.
