Sir Arthur Conan Doyle was born in Edinburgh in 1859 and died in 1930. His greatest achievement was his creation of Sherlock Holmes, who soon attained international status and constantly distracted him from his other work. And in his creation of Dr Watson, Holmes's companion in adventure and chronicler, Conan Doyle produced not only a perfect foil for Holmes but also one of the most famous narrators in fiction.
