Sir Arthur Conan Doyle

Sir Arthur Conan Doyle was born on 22 May 1859 in Edinburgh, Scotland, and died on 7 July 1930. Though trained as a physician, he is best remembered as the creator of Sherlock Holmes, the consulting detective who defined modern crime fiction through four novels and fifty-six short stories. Doyle began writing while studying medicine at the University of Edinburgh Medical School, and his early sea voyages as a ship's doctor inspired the story "J. Habakuk Jephson's Statement," which popularized the mystery of the Mary Celeste. His first Holmes novel, *A Study in Scarlet*, appeared in 1887, but the character truly took off with the monthly *Strand Magazine* series starting with "A Scandal in Bohemia" in 1891. Doyle grew ambivalent about Holmes and killed him off in "The Final Problem" (1893), but public outcry forced his return in *The Hound of the Baskervilles* (1901); he continued writing Holmes stories until 1927. He also created Professor Challenger in *The Lost World* (1912), which lent its name to a speculative fiction subgenre, and wrote humorous tales about the Napoleonic soldier Brigadier Gerard. A prolific writer, Doyle produced over 200 stories and articles, four poetry volumes, and several plays. He was knighted in 1902, campaigned for justice—personally investigating two closed cases that led to exonerations and helped establish the Court of Criminal Appeal—and later embraced spiritualism after family tragedies. His work remains foundational in crime and adventure fiction.
