Grady Memorial Hospital, named after the editor of the Atlanta Constitution Henry Grady, opened in 1892 as a hospital for low-income families. In later years it broadened it's mandate to provide emergency care and other services to all, becoming one of the busiest Level I trauma centers in the country and the largest hospital in Georgia. Originally located on 36 Butler Street, the hospital changed locations three times, opening its fourth location on 80 Butler Street in 1954. Hospital operations were administered by the city of Atlanta until 1944, the Fulton/DeKalb Hospital Authority between 1945 and 2008, and the non-profit organization Grady Memorial Hospital Corporation after 2009. Grady has worked with student doctors at Atlanta Medical College (which became the the Emory University School of Medicine) and Morehouse School of Medicine. The hospital also operated in-house nursing schools from 1898 until 1982. Between 1912 and 1964 Grady was racially segregated, with separate nursing schools for whites and African Americans and a private hospital, called the Hughes Spalding Pavilion, for African American patients to be treated by African American physicians. The Grady Health System has expanded over the years to include many departments and clinics, including the Steiner Clinic, the Georgia Poison Center, the Georgia Comprehensive Sickle Center, and the Ponce De Leon HIV/AIDS Center, amongst others.
