What is the surname of House M.D.’s diagnostician Dr. Eric?

The surname of Dr. Eric in House M.D. is Foreman.

Dr. Eric Foreman is a neurologist and one of House’s original diagnostic fellows. Omar Epps portrayed him throughout the series, beginning with the 2004 premiere. Foreman is intelligent, ambitious, and more cautious than House, though repeated exposure to House’s methods influences his own approach to difficult cases.

Foreman’s background includes juvenile delinquency and a history of stealing cars, details that distinguish him from the polished image he later builds as a physician. His specialty in neurology is especially useful in cases involving the brain, nerves, seizures, movement, and unexplained changes in behavior.

Foreman eventually becomes part of the hospital administration. In the series finale, he is the dean of medicine at Princeton-Plainsboro and discovers evidence that House is alive after House secretly stages his death. The surname is spelled Foreman, not Forman, a common written mix-up.
