Which fictional detective is Gregory House modeled on in House, M.D.?

Gregory House is modeled on Sherlock Holmes in House, M.D. Both characters are exceptionally observant, solve difficult puzzles through deduction, and often disregard social conventions.

The connection appears in several details. House and Holmes share the initials “H,” live at addresses that echo one another, and have a close friend whose name recalls Holmes’s companion Dr. John Watson. House also plays the piano, while Holmes is associated with the violin.

The medical cases function like detective mysteries. Symptoms are clues, tests reveal evidence, and House’s final diagnosis resembles the solution to a case. The show adapts Holmes’s investigative method to medicine rather than crime.

House is not a direct retelling of a particular Sherlock Holmes story. He is a modern medical reinterpretation of Holmes’s personality, methods, relationships, and habits.
