Meredydd Evans, known colloquially as Merêd, was a collector, editor, historian and performer of folk music of Wales. A major figure in Welsh media for over half a century, Evans has been described as influencing "almost every sphere of Welsh cultural life, from folk music and philosophy to broadcasting and language politics".
Evans first found prominence as a member of the popular singing group Triawd y Coleg. Beginning in the 1950s, he made award-winning Welsh language recordings and published collections and research in collaboration with his American-born wife Phyllis Kinney, helping to preserve and promote Welsh music worldwide. Evans served as Head of Light Entertainment at BBC Wales between 1963 and 1973 and was a leading campaigner for Welsh language rights. The archives of Evans and Kinney are now part of the Welsh Music Archive at the National Library of Wales.
