It is oil on canvas and measures 8 feet (240 cm) by 6.5 feet (200 cm). Dr. Samuel D. Gross, a seventy-year-old professor dressed in a black frock coat, lectures a group of Jefferson Medical College students. Included among the group is a self-portrait of Eakins, who is seated to the right of the tunnel railing, sketching or writing. Seen over Dr. Gross`s right shoulder is the clinic clerk, Dr. Franklin West, taking notes on the operation. Eakins`s signature is painted into the painting, on the front of the surgical table.
