Arthur Conan Doyle (1859–1930) was a British writer and physician, best known for creating the fictional detective Sherlock Holmes, one of the most vivid and enduring characters in English literature. Born in Edinburgh, Scotland, Doyle studied medicine at the University of Edinburgh, where he began writing short stories. His medical career led him to become a ship's surgeon and eventually set up a private practice, though it was his literary pursuits that garnered him fame. Doyle first introduced Sherlock Holmes in 1887 in 'A Study in Scarlet'. The character, along with his companion Dr. John Watson, became immensely popular, leading to a series of novels and short stories. Doyle's works are celebrated for their intricate plotting, memorable characters, and vivid depiction of Victorian and Edwardian-era society.
