Arthur Conan Doyle Arthur Conan Doyle Sir Arthur Ignatius Conan Doyle (22 May 1859 – 7 July 1930) was a British writer best known for his detective fiction featuring the character Sherlock Holmes. Originally a physician, in 1887 he published "A Study in Scarlet", the first of four novels about Holmes and Dr. Watson. In addition, Doyle wrote over fifty short stories featuring the famous detective. The Sherlock Holmes stories are generally considered milestones in the field of crime fiction.

Sherlock Holmes link between medical investigation and the detection of crime. Other inspirations have been considered. One is thought to be Francis "Tanky" Smith, a policeman and master of disguise who went on to become Leicester's first private detective. Another might be "Maximilien Heller", by French author Henry Cauvain. It is not known if Conan Doyle read "Maximilien Heller", but he was fluent in French, and in this 1871 novel (sixteen years before the first adventure of Sherlock Holmes), Henry Cauvain imagined a depressed, anti-social, polymath, cat-loving, and opium-smoking Paris-based detective. Details about Sherlock Holmes' life are scarce in Conan Doyle's stories.
