House M.D.’s Dr. Gregory House is primarily based on which literary detective?

House M.D.’s Dr. Gregory House is primarily based on Sherlock Holmes. The connection is intentional: both characters solve mysteries through observation, deduction, and unconventional reasoning.

The parallels extend beyond the detective premise. House lives at 221B, the same number associated with Holmes’s Baker Street residence, and House’s surname echoes “Holmes.” Dr. James Wilson serves as a Watson-like companion, while House’s drug dependence recalls Holmes’s use of cocaine in the original stories. Moriarty-like adversarial elements also appear in the series.

The adaptation changes the kind of mystery. Holmes investigates crimes, while House investigates diseases and symptoms. Patients provide the clues, laboratory results replace physical evidence, and the diagnosis functions as the solution to the case.

House is not a direct screen adaptation of one Sherlock Holmes story. He is an original medical character built from Holmesian motifs. This is why the correct literary reference is Sherlock Holmes rather than another famous detective such as Hercule Poirot.
