The surname of House M.D.’s original diagnostic-team doctor Eric is Foreman.
Dr. Eric Foreman, played by Omar Epps, is one of the three physicians selected for House’s original diagnostic team alongside Robert Chase and Allison Cameron. Foreman is a neurologist whose analytical skills and independence make him an important member of the group.
The character often challenges House’s methods while still learning from his diagnostic approach. Over the series, Foreman takes on additional leadership and administrative responsibilities, reflecting his development from team member to senior physician.
Chase, Taub, and Kutner are common mix-ups because each is also a doctor who works with House at different points. Robert Chase belongs to the original team, while Chris Taub and Lawrence Kutner join later. Eric Foreman is specifically the neurologist and original team member played by Epps.
