House M.D.'s Gregory House was primarily inspired by which fictional detective?

Gregory House in House M.D. was primarily inspired by the fictional detective Sherlock Holmes.

The connection appears in the character’s name, his reliance on deductive reasoning, and his habit of solving seemingly impossible cases through observation and unusual clues. “House” also echoes “Holmes,” while his friend James Wilson parallels Dr. John Watson in the source stories.

Both characters are brilliant investigators who can be socially difficult, impatient with ordinary procedures, and fascinated by puzzles. House applies those methods to medical diagnosis rather than criminal investigation. The series also includes additional Holmes references, including the address 221B Baker Street, associated with Holmes in Arthur Conan Doyle’s stories.

House is not a direct adaptation of one Holmes story. Instead, the show transposes the detective archetype into a hospital setting. That distinction matters: Holmes investigates crimes, while House investigates diseases and bodily symptoms.
