July 9, 1893 – Dr. Daniel Hale Williams performed one of the earliest cardiac surgeries when he replaced a patient’s pericardium at Chicago’s Provident Hospital.
Black doctors were not allowed to work in Chicago hospitals during the time that he graduated from medical school. As a result, in 1891, Williams started the Provident Hospital and training school for nurses in Chicago.
In the 1890's, there were many attempts to perform a surgery of this kind. Williams performed one of the first successful operations on James Cornish, a knife wound patient.
