About Arthur Conan Doyle:
Sir Arthur Ignatius Conan Doyle (22 May 1859 – 7 July 1930) was a British writer and medical doctor. He created the character Sherlock Holmes in 1887 when he published A Study in Scarlet, the first of four novels and more than fifty short stories about Holmes and Dr. Watson. The Sherlock Holmes stories are generally considered milestones in the field of crime fiction.
Doyle was a prolific writer; other than Holmes stories, his works include fantasy and science fiction stories about Professor Challenger and humorous stories about the Napoleonic soldier Brigadier Gerard, as well as plays, romances, poetry, non-fiction and historical novels. One of Doyle's early short stories, "J. Habakuk Jephson's Statement" (1884), helped to popularise the mystery of the Mary Celeste. (from wikipedia)
