Trevor H. Hall
He was born in Wakefield, England. He served as a major in the British army during World War II (1939–45) and became a senior partner of V. Walker and Son (chartered surveyors) (1945–80), he was the vice president of the Huddersfield Building Society (1958–80).
He had a deep interest in magic and mystery. Hall was a student in psychical research at Trinity College, Cambridge (1954–56). His knowledge of conjuring and magic helped him discover the tricks of mediums, many of whom had been caught in fraud. In his book The Spiritualists (1964) he wrote that the phenomena of the famous medium Florence Cook were fraudulent and that William Crookes had an affair with her. Hall was an ex-member and critic of the Society for Psychical Research and published a series of sceptical books on the paranormal and psychical research.
Researcher Georgess McHargue noted that Hall was "one of the most astute of modern investigators, combining twentieth-century scientific techniques with a cheerful and readable writing style in his many books."
