As surgeon of the South Side Dispensary in Chicago (1884–91), he became keenly aware of the lack of facilities for training African Americans like himself as doctors and nurses. As a result he organized the Provident Hospital, the first black hospital in the United States. In 1893, Williams performed the first successful closure of a wound of the heart and pericardium. In the same year President Cleveland appointed him surgeon in chief of Freedmen's Hospital, Washington, D.C., and during his five-year tenure there he reorganized the hospital and provided a training school for African American nurses. From 1899 until his death he was professor of clinical surgery at Meharry Medical College, Nashville, Tenn
