The Gross Clinic is one of the best known works by Thomas Eakins (1844-1916). He was an American painter who was a standard bearer for the Realism movement. In the painting is depicted Dr. Samuel D. Gross, a teacher and surgeon at the Jefferson Medical
College in Philadelphia, engaged in a teaching demonstration of a
surgical procedure for the medical students seated behind him. Five other doctors operate on a patient's infected thigh. The 1875 painting was considered extreme and controversial.
