Arthur Conan Doyle (1859–1930) was a Scottish physician and author who in 1887 introduced Sherlock Holmes, arguably the best-known fictional detective. He also wrote poetry, historical novels, influential gothic short stories, and more. Doyle’s proto-sf series of Professor Challenger adventures include the novels The Lost World (1912), The Poison Belt (1913), and The Land of Mist (1926), and the short stories “When the World Screamed” (1928) and “The Disintegration Machine” (1929).
