Arthur Conan Doyle (1859-1930)was a British physician, novelist, and detective-story writer who was born in Edinburgh, and educated at Stonyhurst College and the University of Edinburg. From 1882 to 1890 Arthur Conan Doyle practiced medicine in Southsea, England. A Study in Scarlet, the first of sixty-eight stories featuring his famous fictional detective, Sherlock Holmes, appeared in 1887. Arthur Conan Doyle was so speedily successful in his literary career that about five years later he abandoned his medical practice to devote his entire time to writing.
The Holmes stories, of which the best known are The Sign of the Four (1889), The Adventures of Sherlock Holmes (1891), and The Hound of the Baskervilles (1902), made Arthur Conan Doyle internationally famous. His remarkable literary versatility brought him equal fame for his historical romances, such as Micah Clarke (1888), The White Company (1890), and Sir Nigel (1906).
Arthur Conan Doyle served in the Boer War as a physician, and on his return to England wrote The Great Boer War (19000 And The War in South Africa; Its Causes and Conduct (1902), for which he was knighted in 1902. During World War 1, he wrote History of the British Campaign in France and Flanders (6 vols., 1915-20) as a tribute to British bravery.
After the death of his eldest son in the war, Arthur Conan Doyle became an advocate of spiritualism and toured Australia, Africa, and the U.S. in the interest of his new belief. During the last part of his life, he wrote extensively on spiritualism.
