Arthur Ford (1897–1971)

Famous for the Houdini séance and studied by researchers including William Roll. (well known for his research into poltergeist activity, apparitions and paranormal experiences writ large) Arthur Ford is unquestionably one of the best known "celebrity" mediums of the last several hundred years, but that doesn't mean he didn't have his many detractors. His reputation is somewhat complicated by later controversies, but he remains one of the most investigated mediums of the 20th century and many investigators found aspects of his work genuinely puzzling.
