Which fictional character inspired Gregory House in the television series House M.D.?

Sherlock Holmes inspired Gregory House in the television series House M.D. The connection is deliberate: both characters solve mysteries through observation, deduction, and unconventional reasoning rather than through ordinary social cooperation.

The parallels appear in names and relationships as well as personality. House’s closest friend is James Wilson, whose role echoes Dr. John Watson. House lives at 221B Baker Street, the famous address associated with Holmes, and both characters struggle with dependence on drugs.

House M.D. translates detective fiction into a medical setting. A patient’s symptoms function like clues, a diagnosis functions like the solution, and the team tests hypotheses in stages. The inspiration does not mean House is a direct adaptation of one Holmes story; the series uses the detective’s structure and character traits in an original hospital drama.
