Born in Tolworth, Surrey, the son of William Henry Wheatley, a bank clerk, and his wife Rose, Alan Wheatley was initially an industrial psychologist. Later, he worked as a radio announcer before turning to stage and screen acting in the 1930s, as a player during the black-and-white era of film and television. Wheatley made his film debut in Conquest of the Air, which remained unreleased for four years. During the Second World War, he worked for BBC Radio, as both an actor and an announcer. It was during this time as a newsreader for the BBC's European Service that he became interested in the work of Federico García Lorca after meeting a friend of the poet, Rafael Martínez Nadal, who was broadcasting a weekly programme to Spain. Wheatley subsequently made translations of Lorca's Spanish poetry; his performance of nine of these translations, released with Argo Records in 1953, became the first recorded collection of Lorca's work in English. Wheatley starred as Sherlock Holmes in the 1951 BBC TV series, which was the first such series though not the Holmes character's first appearance on television. The programme aired live for six episodes, and apparently no recordings were made. In the later Robin Hood series, Wheatley appeared regularly as the Sheriff in the first three seasons; in the fourth and final season, his role was mostly taken over by that of the Deputy Sheriff as a result of Wheatley's departure from the series. He also had roles in Danger Man and The Avengers. Wheatley played the first character to be killed on-screen by a Dalek in Doctor Who, when he appeared as Thal leader Temmosus in the 1963-64 serial The Daleks. His film credits include: Caesar and Cleopatra, The Rake's Progress, Appointment with Crime 1946, Brighton Rock, Calling Paul Temple, The Pickwick Papers, Spaceways, Simon and Laura, A Jolly Bad Fellow and Tomorrow at Ten among others. He also appeared in Inn for Trouble, a film spin-off of the TV comedyThe Larkins. Wheatley was also a prolific stage actor. His theatre credits included Clifford Bax's The House of Borgia, the lead in This Way to the Tomb, and the tormented soul, Harry, in The Family Reunion. He appeared in two versions of the thriller play Rope, in 1950 and 1953, and starred as Abanazar in the Cole Porter musical pantomime Aladdin at the London Coliseumin 1960. He also played the Abbé in a BBC radio adaptation of The Count of Monte Cristo, with Andrew Sachs in 1987, and the High Lama in the 1981 BBC Radio 4 "Classic Serial" version of Lost Horizon, with Derek Jacobi as Hugh Conway. Wheatley died in Westminster, London in 1991.
