Which fictional detective is the main inspiration for Gregory House in House M.D.?

Sherlock Holmes is the main fictional detective inspiration for Gregory House in House M.D.

The connection appears in several deliberate details. House and Holmes both rely on observation, deduction, and unconventional reasoning, while House’s surname echoes Holmes’s. Dr. James Wilson serves as a counterpart to Dr. John Watson, Holmes’s friend and chronicler.

House also lives at apartment 221B, a reference to 221B Baker Street, Holmes’s famous London address. The medical cases function like detective mysteries: symptoms are clues, the patient’s story may be incomplete, and the diagnostic team tests competing explanations.

House is not a direct adaptation of a single Holmes story. Instead, the series transfers the detective’s methods and personality traits into a hospital setting. House’s medical expertise replaces Holmes’s criminal investigations, while his addiction, difficult temperament, and reliance on a close friend develop the comparison in a modern television context.
