The Gross Clinic [SEP] Description
Admired for its uncompromising realism, "The Gross Clinic" has an important place documenting the history of medicine—both because it honors the emergence of surgery as a healing profession (in previous years surgery was associated primarily with Amputation, which caused severe medical complications, later killing the person) , and because it shows what an surgical theater looked like in the nineteenth century. The painting is based on a surgery witnessed by Eakins, in which Gross treated a young man for osteomyelitis of the femur. Gross is pictured here performing a conservative operation, as opposed to the amputation normally carried out. Here, surgeons crowd around the anesthetized patient in their frock coats—this is just prior to the adoption of a hygienic surgical environment (see asepsis).
