Sir Arthur Conan Doyle, True Believer
When Sir Arthur Conan Doyle spoke out in support of spiritualism and the possibility that some spirit photographs could not be explained, he came from a place of pain and hope. Doyle dabbled in spirituality since 1887, attending seances and exploring telepathy. He had suffered loss with the death of his wife Louisa to tuberculosis in 1906. Shortly after, he lost his son Kingsley in 1918 from pneumonia as the young man was recovering from injuries during World War I. Doyle took comfort in the idea of breaking the veil between the living and dead, reinforcing his already strong belief in spiritualism. His spiritualist belief and staunch defense in its possibility led to a split with his friend, the vocal skeptic Houdini. But Doyle was steadfast in his belief in spiritualism and held on to that belief even when it was denounced in a very public manner.
