Arthur Conan Doyle (1859–1930) was a British physician and literary trailblazer whose diverse career spanned medicine and storytelling. Best known as the creator of Sherlock Holmes, introduced in A Study in Scarlet (1887), Doyle revolutionized crime fiction through the detective’s scientific deduction and partnership with Dr. Watson, featured in four novels and 56 short stories. Beyond Holmes, his eclectic output included fantasy and science fiction (such as the Professor Challenger series), historical adventures (like the swashbuckling Brigadier Gerard tales), and mystery—notably his 1884 story J. Habakuk Jephson’s Statement, which reignited intrigue around the real-life ghost ship Mary Celeste. A polymathic writer, Doyle also penned plays, poetry, nonfiction, and social commentaries, reflecting his versatility and curiosity. Though Holmes overshadowed his other works, Doyle’s legacy endures as a master of genre-blending narratives and a keen observer of human ingenuity.
