Which literary detective is the character Gregory House partly based on?

Gregory House is partly based on Sherlock Holmes, the detective created by Arthur Conan Doyle. House M.D. adapts several Holmesian ideas to a medical setting, where diagnosis replaces traditional detective investigation.

Both characters rely on observation, deduction, and unusual interpretations of evidence. House’s surname resembles “Holmes,” his apartment number is 221B in the series, and his friendship with James Wilson parallels Holmes’s relationship with Dr. John Watson. House also plays musical instruments, echoing Holmes’s violin playing.

The connection does not mean House is a direct retelling of one Holmes story. Instead, the series uses the detective as a structural and character influence. Patients provide the mysteries, symptoms serve as clues, and the diagnostic team tests competing explanations.

Hercule Poirot and Miss Marple are also famous fictional detectives, but they are characters created by Agatha Christie. The specific literary detective associated with House’s design is Sherlock Holmes.
