Sir Arthur Ignatius Conan Doyle, DL (22 May 1859 - 7 July 1930) was a Scottish[1] physician and writer, most noted for his stories about the detective Sherlock Holmes, which are generally considered a major innovation 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, historical novels, plays and romances, poetry, and non-fiction.
Arthur Conan Doyle was born on 22 May 1859 in Edinburgh, Scotland, to an English father of Irish descent, Charles Altamont Doyle, and an Irish mother, nee Mary Foley. His parents were married in 1855.[2]
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 the simple 'Doyle' as his surname. It also names Michael Conan as his godfather.[3]
