What is the name of House M.D.’s Sherlock Holmes-inspired protagonist?

The Sherlock Holmes-inspired protagonist of House M.D. is Dr. Gregory House. The character’s name, investigative method, and relationship with James Wilson deliberately echo Arthur Conan Doyle’s famous detective and Dr. John Watson.

House solves medical cases by treating symptoms as clues. He forms hypotheses, tests them, discards explanations that fail, and searches for a hidden cause that unifies the evidence. This resembles Holmes’s deductive investigations, although House works in a hospital rather than a detective’s office.

Additional parallels include House’s apartment number, 221B, and his dependence on Vicodin, which recalls Holmes’s drug use in the original stories. Wilson’s role as a close friend and observer also reflects the Watson pattern.

The inspiration does not mean House is literally Sherlock Holmes or that Wilson is named John Watson. Gregory House is an original television character, played by Hugh Laurie, with the literary references woven into his characterization and the show’s structure.
