Which fictional detective inspired Gregory House’s character in House M.D.?

Sherlock Holmes inspired Gregory House’s character in House M.D. The show adapts several elements of Arthur Conan Doyle’s detective stories into a medical setting.

Like Holmes, House solves cases through observation, deduction, and unusual interpretations of evidence rather than through conventional social behavior. House’s surname echoes Holmes’s home, 221B Baker Street, while House’s apartment number is 221B. His friendship with James Wilson also parallels Holmes’s relationship with Dr. John Watson.

Other parallels include House’s drug dependence, his skill with an instrument, and the use of a diagnostic team that helps supply perspectives while he leads the central reasoning. The medical cases function like detective mysteries, with symptoms serving as clues.

House is not a direct screen adaptation of a particular Holmes story. Instead, the series reworks Holmesian character traits and plot patterns for hospital diagnosis, which is why the inspiration is Sherlock Holmes rather than another fictional detective.
