Sir Arthur Conan Doyle (1859 – 1930) – British writer and physician. He created the character Sherlock Holmes in 1887 for A Study in Scarlet, the first of four novels and fifty-six short stories about Holmes and Dr. Watson.
Doyle had a longstanding interest in mystical subjects and remained fascinated by the idea of paranormal phenomena, even though the strength of his belief in their reality waxed and waned periodically over the years.
