What is the full name of House M.D.’s oncologist character Wilson?

The full name of House M.D.’s oncologist character Wilson is James Evan Wilson.

Robert Sean Leonard played Dr. James Evan Wilson, who serves as Gregory House’s closest friend and an important emotional counterweight to him. Wilson is an oncologist at Princeton-Plainsboro Teaching Hospital, so his work often brings him into contact with seriously ill patients and difficult end-of-life decisions.

The friendship between Wilson and House is one of the show’s defining relationships. Wilson is generally more empathetic and socially accommodating, while House is more confrontational and skeptical. Their contrasting personalities echo the Holmes-and-Watson pattern that influenced House’s creation.

The middle name is easy to miss because the series usually calls him James Wilson or simply Wilson. It appears in character references and related material, while “Wilson” alone is the name most often used in dialogue. Robert Sean Leonard remained a principal cast member through the series and helped anchor its personal storylines.
