Sir Arthur Ignatius Conan Doyle KGStJ, DL (22 May 1859 � 7 July 1930) was a British physician and writer who is most noted for his fictional stories about the detective Sherlock Holmes, which are generally considered milestones in the field of crime fiction.

He wore rather baggy gray shepherd's check trousers, a not overclean black frock coat, unbuttoned in the front, and a drab waistcoat with a heavy brassy Albert chain, and a square pierced bit of metal dangling down as an ornament.
