In House M.D., Dr. Wilson’s first name is James.
James Wilson is the longtime friend and colleague of Gregory House. He is an oncologist at Princeton-Plainsboro Teaching Hospital and often provides the emotional counterweight to House’s abrasive, highly analytical personality. Unlike House, Wilson usually approaches patients and colleagues with empathy and diplomacy.
The character is played by Robert Sean Leonard. A common mix-up is confusing the actor’s first name, Robert, with the character’s first name, James. The series identifies him as Dr. James Evan Wilson, while “Wilson” is the surname used most often in dialogue.
Wilson’s friendship with House is central to the show’s story. Their relationship survives arguments, professional conflicts, and House’s risky behavior, making Wilson one of the program’s most important recurring characters.
