The title character in House M.D., played by Hugh Laurie, is named Gregory House.
Dr. House is a fictional diagnostician whose unusual methods drive the medical drama. He leads a team that investigates difficult cases at the fictional Princeton-Plainsboro Teaching Hospital in New Jersey. The surname is also the basis of the show's title.
House is loosely inspired by Sherlock Holmes. Both characters are brilliant investigators, live with serious personal flaws, and rely on sharp observation and deduction. The connection is reinforced by details such as House's address, 221B Baker Street, which echoes Holmes's famous London residence.
A common mix-up is confusing House's surname with the names of his colleagues, including James Wilson, Eric Foreman, and Robert Chase. Those characters are important members of the ensemble but are not the show's title character.
