Ronald Radd (born 22 January 1929 – 23 April 1976) was a British television actor.
Radd began as a stage actor in the Alexandra Theatre in Birmingham in the early-1950s, along with the likes of Leslie Sands and Edward Mulhare. In 1951 he appeared opposite Jean Charlesworth and Peter Bell in a Lionel Hamilton production of The Romantic Young Lady at the Kettering Savoy. By 1954, Radd had graduated to the West End, where he was appeared with Kenneth Williams in two different productions in the Apollo Theatre in February 1956, The Buccaneer and The Boy Friend. Several months later, he was again with Kenneth Williams in a revival (at the Winter Garden) of Feydeau's Hotel Paradiso, but the billing went to Alec Guinness, who made a film of it years later, but not with Radd or Williams.
Radd gradually lost interest in theatre and broke into television in Ordeal by Fire in 1957 as a dastardly Frenchman, a single play costume piece involving Joan of Arc (played by Elizabeth Sellars) with Peter Wyngarde and Patrick Troughton whom he appeared with in the BBC production of A Tale Of Two Cities (1958).
