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

Sherlock Holmes inspired House M.D.’s title character.

Gregory House is modeled in part on Arthur Conan Doyle’s Sherlock Holmes. Both characters are exceptionally skilled investigators who rely on deduction, notice details others miss, and often behave in ways that frustrate colleagues and friends.

The connection appears in several details. House’s surname resembles Holmes’s, his closest friend is named Wilson rather than Watson, and the series repeatedly treats medical diagnosis as a form of investigation. House also lives at 221B Baker Street, the famous address associated with Holmes, although the show places it in New Jersey.

House is not simply a modernized copy of Holmes. His cases involve physiology, laboratory evidence, and treatment decisions, while his drug dependence and chronic leg pain create a distinct medical and emotional history. The Holmes influence is therefore a structural and thematic foundation rather than the character’s complete identity.
