Sir Arthur Ignatius Conan Doyle DL (22 May 1859 – 7 July 1930) was a Scottish physician and writer, most noted for his stories about the detective Sherlock Holmes, generally considered a milestone in the field of crime fiction, and for the adventures of Professor Challenger. He was a prolific writer whose other works include science fiction stories, plays, romances, poetry, non-fiction, historical novels and humours ('Exploits of Brigadier E.Gerard').
Arthur Conan Doyle was born the third of ten siblings on 22 May 1859 in Edinburgh, Scotland. His father, Charles Altamont Doyle, who was born in England of Irish descent, and his mother, born Mary Foley, who was Irish, had married in 1855. Doyle's father died in 1893, in the Crichton Royal, Dumfries, after many years of psychiatric illness.
Although he is now referred to as "Conan Doyle", the origin of this compound surname (if that is how he meant it to be understood) is uncertain. The entry in which his baptism is recorded in the register of St Mary's Cathedral in Edinburgh gives "Arthur Ignatius Conan" as his Christian name, and simply "Doyle" as his surname. It also names Michael Conan as his godfather.
Conan Doyle was sent to the Roman Catholic Jesuit preparatory school Hodder Place, Stonyhurst, at the age of nine. He then went on to Stonyhurst College until 1875. From 1875 to 1876 he was educated at the Jesuit school Stella Matutina in Feldkirch, Austria.
From 1876 to 1881 he studied medicine at the University of Edinburgh, including a period working in the town of Aston (now a district of Birmingham) and in Sheffield. While studying, Conan Doyle also began writing short stories; his first published story appeared in Chambers's Edinburgh Journal before he was 20. Following his term at university, he was employed as a ship's surgeon on the SS Mayumba during a voyage to the West African coast. He completed his doctorate on the subject of tabes dorsalis in 1885.
