Founded in December 1861 as the Samuel R. Smith Infirmary, the institution adopted its current name during the 1990s with the merger of Staten Island Hospital (now the North Campus) and the Richmond Memorial Hospital (now the South Campus). SIUH maintains an academic affiliation with the State University of New York Downstate Medical Center College of Medicine and Touro College of Osteopathic Medicine, whose medical students and residents complete a portion of their training at SIUH. SIUH also operates, in conjunction with Wagner College, a Physician Assistant training program and a Physician Assistant Fellowship in Emergency Medicine.
