Originally named Penitentiary Hospital and located on what was then known as Blackwell's Island, the first hospital was built in 1832 to serve the prisoners housed at Blackwell's Penitentiary. After the hospital was destroyed by a fire in 1858, architect James Renwick Jr. designed a new building to be called City Hospital, on which prisoners completed construction in 1861. It served both inmates and New York City's poorer population. In 1870, the hospital was renamed Charity Hospital and a medical superintendent was hired after the quality of care was criticized.
