Arthur Conan Doyle
Land of Mist.
His book, The Coming of the Fairies (1921) shows he was apparently convinced of the
veracity of the Cottingley Fairies photographs, which he reproduced in the book, together
with theories about the nature and existence of fairies and spirits.
In his The History of Spiritualism (1926) Conan Doyle praised the psychic phenomena
and spirit materialisations produced by Eusapia Palladino and Mina "Margery" Crandon.
His work on this topic was one of the reasons that one of his short story collections, The
Adventures of Sherlock Holmes, was banned in the Soviet Union in 1929 for supposed
occultism. This ban was later lifted. Russian actor Vasily Livanov later received an Order
of the British Empire for his portrayal of Sherlock Holmes.
Conan Doyle was friends for a time with the American magician Harry Houdini, who
himself became a prominent opponent of the Spiritualist movement in the 1920s
