J. Arthur (John Arthur) Hill

John Arthur Hill (4 December 1872 – 22 March 1951) was a British writer and psychical researcher. Reliable sources describe him as a prolific author on telepathy, clairvoyance, mediumship, spiritualism, and related subjects, and note that he is credited with coining the phrase "out-of-the-body experience." Before turning fully to writing and study, he worked in business and later reduced his professional activity because of poor health.

Accounts of his work emphasize that he tried to treat extraordinary claims seriously without rushing to sensational conclusions. Rather than presenting every unusual event as proof of the supernatural, he often argued for careful observation and a measured, investigative approach.

Hill wrote books including Man Is a Spirit and Spiritualism: Its History, Phenomena and Doctrine. His reputation today rests on the way he combined curiosity, skepticism, and openness while exploring one of the strangest corners of early 20th-century thought.
