Which Sherlock Holmes character inspired Gregory House in House M.D.?

Gregory House in House M.D. is inspired by Sherlock Holmes.

The connection appears in the characters’ shared emphasis on deduction, their unusual personalities, and their ability to notice clues that others overlook. House’s surname also echoes Holmes, and several story details deliberately reference Arthur Conan Doyle’s detective.

House’s friend James Wilson serves as a Watson-like companion, while the medical cases function as mysteries that must be solved through observation and reasoning. House also plays the piano and guitar, uses drugs, and lives at 221B Baker Street in one episode—details that reinforce the literary connection.

House M.D. is not a direct retelling of the Holmes stories. It relocates the detective model to a hospital, where symptoms, test results, and patient histories replace criminal clues. The inspiration explains the show’s structure while leaving House as an original television character.
