Sir Arthur Conan Doyle (1859–1930) was a Scottish physician and writer known around the world for his stories about detective Sherlock Holmes, which all but created the literary field of crime fiction and made the name Sherlock Holmes synonymous with detectives. Aside from the Sherlock Holmes stories, he was a prolific writer whose other works include science fiction stories, historical novels, plays and romances, poetry, and non-fiction.
