Which literary detective is the main inspiration for Gregory House in House M.D.?

Sherlock Holmes is the main literary inspiration for Gregory House in House M.D.

The series adapts several elements of Arthur Conan Doyle’s detective stories to a medical setting. House solves diagnostic mysteries through observation, deduction, and the recognition of clues that other doctors overlook. His surname resembles Holmes’s, and his closest friend James Wilson occupies a role structurally comparable to Dr. Watson.

The references extend beyond the characters’ broad personalities. House lives at 221B, matching Holmes’s famous Baker Street address, and both characters are portrayed as brilliant, difficult, and isolated figures who rely on a trusted companion. House’s occasional use of drugs also recalls Holmes’s canonical drug use, though their circumstances and substances differ.

House is not a direct retelling of a particular Holmes case. Instead, the show transfers the detective format and relationship dynamics into Princeton-Plainsboro’s diagnostic department, making medical diagnosis function like criminal investigation.
