Who created Sherlock Holmes in the original stories?

Arthur Conan Doyle created Sherlock Holmes in the original stories.

Doyle was a Scottish physician and writer who introduced Holmes in the 1887 novel A Study in Scarlet. Holmes was presented as a consulting detective whose skill came from observation, deduction, and knowledge of forensic details. Doyle based some of Holmes’s reasoning methods on Dr Joseph Bell, one of his teachers at the University of Edinburgh medical school.

Holmes later appeared in four novels and 56 short stories. Although Doyle sometimes became frustrated with the character’s popularity, Holmes became the most famous figure in his fiction. The stories are narrated mainly by Dr John Watson, whose account gives the detective’s investigations their distinctive literary form.

A common mix-up is crediting Doyle only with the character rather than the complete Holmes canon. Other writers have since produced authorized and unofficial Holmes adventures, but Doyle originated the character and the original series.
