Thomas Charles Lethbridge (3 March 1901 – 30 September 1971) was a British explorer, archaeologist and parapsychologist. According to the historian Ronald Hutton, Lethbridge's "status as a scholar never really rose above that of an unusually lively local antiquary" for he had a "contempt for professionalism in all fields" and purported theories that were never accepted by the mainstream archaeological community.
Lethbridge was educated at Wellington College, before attending Trinity College, Cambridge, Cambridge University at the age of eighteen, where he discovered an interest in archaeology. Once he had completed his degree, he began working as a voluntary digger for Louis Clarke, the curator of the Archaeological Museum in Cambridge. Although he had a private income, Lethbridge became the keeper of Anglo-Saxon antiquities at the museum. He remained in Cambridge until 1957, bored with what he called “the academic trade-unionism” that existed within his profession. During this time he wrote a series of books about Early Medieval Britain. These, however, are generally eclipsed by the much more famous and controversial series of books he wrote at his home, Hole House, in Branscombe, Devon between 1961 and his death in 1971. Lethbridge claimed there is a link between the length of a pendulum and the object being doused for (see 'external links' below).
Lethbridge was a dedicated researcher who considered matters known as "the occult" with what he considered to be a scientific approach and put forward theories on ghosts, witchcraft, dowsing, psychokinesis and even aliens. His book The Power of the Pendulum, documents his research into dowsing by means of the pendulum. Lethbridge died while the book was still in draft form.
The book is a conclusion to the author's lifelong study of the worlds of the unexplained and the occult. Through his experience with the pendulum and his work with dreams, Lethbridge concluded that there are other realms of reality beyond this one and that the soul is probably immortal.
Whilst Lethbridge and his theories were largely ignored by the archaeological community following his death, interest in him and his parapsychological ideas has been maintained within the esoteric community. In 2003, a group of admirers of his work calling themselves "the Hula-Sons of T.C. Lethbridge" (Doggen Foster, Kevlar Bales and Welbourn Tekh), with the aid of Julian Cope and Colin Wilson, released A Giant: The Definitive T.C. Lethbridge, a set containing a booklet and two CDs containing music accompanying discussions of Lethbridge's work. Terry Welbourn's (Welbourn Tekh) biography entitled T.C. Lethbridge: The Man who Saw the Future is to be published by O-Books on 27th May 2011.
