Richard Dafydd Vivian Llewellyn Lloyd (8 December 1906 – 30 November 1983), better known by his pen name Richard Llewellyn, was a Welsh novelist. Llewellyn (real name Vivian Lloyd ) was born of Welsh parents in Hendon, Middlesex in 1906. Only after his death was it discovered that his claim that he was born in St. Davids, West Wales was false. Several of his novels dealt with a Welsh theme, the best-known being How Green Was My Valley (1939), which won international acclaim and was made into a classic Hollywood film. It immortalised the way of life of the South Wales Valleys coal mining communities, where Llewellyn spent a small amount of time with his grandfather. Three sequels followed. In the U.S., Llewellyn won the National Book Award for favourite novel of 1940, voted by members of the American Booksellers Association. He lived a peripatetic life, travelling widely throughout his life. Before World War II, he spent periods working in hotels, wrote a play, worked as a coal miner and produced his best known novel. During World War II, he rose to the rank of Captain in the Welsh Guards.
