George Lowthian Trevelyan was educated at Sidcot School and Trinity College Cambridge, reading history. He worked as an estate manager and wood craftsman but the majority of his life was spent working in education. He was involved with alternative teaching methods, including the Alexander Technique and Steiner education, and was instrumental in the development of Attingham Park adult education college. In 1940 he married Editha Helen Smith [Helen], and the pair had one adopted daughter. During World War II, George undertook military service on the home front. In later life he became increasingly involved with the Spiritualist movement, and published a number of books.
