Born in Edinburgh, Scotland, Doyle pursued a medical degree at the University of Edinburgh, where he began crafting stories. His literary career was initially marked by a series of historical novels and short stories but it was the creation of Sherlock Holmes and his companion Dr. John H. Watson in 'A Study in Scarlet' (1887) that cemented his place in the literary canon.
