What is Dr. Watson's first name in Conan Doyle's stories?

John H. Watson, known as Dr. Watson, is a fictional character in the Sherlock Holmes stories by Sir Arthur Conan Doyle and was the narrator in the original stories. Watson is Sherlock Holmes's friend, assistant and sometime flatmate, and the first person narrator of all but four of these stories. He is described as the typical Victorian-era gentleman, unlike the more eccentric Holmes. He is astute, although he can never match his friend's deductive skills.

Watson has been adapted in various films, television series, video games, comics, and radio programmes, retaining his role as Holmes's friend and confidant.
