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. Excerpt-There was only one reason which made Ward Mortimer's position a little difficult at the Belmore Street Museum, and that was the extreme eminence of the man whom he had to succeed. Professor Andreas was a profound scholar and a man of European reputation. His lectures were frequented by students from every part of the world, and his admirable management of the collection intrusted to his care was a commonplace in all learned societies. There was, therefore, considerable surprise when, at the age of fifty-five, he suddenly resigned his position and retired from those duties which had been both his livelihood and his pleasure. He and his daughter left the comfortable suite of rooms which had formed his official residence in connection with the museum, and my friend, Mortimer, who was a bachelor, took up his quarters there.
