For All the People

Gastroscopy demonstration, Harlem Hospital

While an attending physician at all-black Provident Hospital in Chicago, Dr. Berry trained in gastroscopy (viewing of the upper digestive system with a flexible tube and camera) with the inventor of the gastroscope, Dr. Rudolph Schindler of the University of Chicago. Later, Berry co-invented a new device, the Eder-Berry gastrobiopsy scope, for taking tissue samples during gastroscopic examination.
