Sir Arthur Conan Doyle is the creator Sherlock Holmes, the best-known detective in literature and the embodiment of scientific thinking. Doyle himself was not a good example of rational personality: he believed in fairies and was interested in occultism. Sherlock Holmes stories have been translated into more than fifty languages, and made into plays, films, radio and television series, a musical comedy, a ballet, cartoons, comic books, and advertisement. By 1920 Doyle was one of the most highly paid writers in the world.
