House M.D. was inspired partly by which fictional detective created by Arthur Conan Doyle?

House M.D. was inspired partly by Sherlock Holmes, the detective created by Arthur Conan Doyle.

The connection appears in several details. Gregory House and Sherlock Holmes are both brilliant investigators who rely on observation, deduction, and unconventional reasoning. Their names also echo each other: House resembles Holmes, while James Wilson parallels Holmes’s friend and narrator, Dr. John Watson.

House’s apartment number, 221B, is another direct reference to the address associated with Holmes in Doyle’s stories. The series also gives House a drug habit, a difficult personality, and an unusual musical ability, all traits that recall elements of Holmes’s characterization.

House M.D. is not a direct retelling of a single Holmes story. Instead, it transfers the detective format into hospital diagnosis, making diseases and symptoms the mysteries that House investigates. Hercule Poirot and Miss Marple are other famous detectives, but neither is the principal literary inspiration identified for the series.
