In 1840, King's opened its own hospital on Portugal Street near Lincoln's Inn Fields, an area composed of overcrowded rookeries characterised by poverty and disease. The governance of King's College Hospital was later transferred to the corporation of the hospital established by the King's College Hospital Act 1851. The hospital moved to new premises in Denmark Hill, Camberwell in 1913. The appointment in 1877 of Joseph Lister as professor of clinical surgery greatly benefited the medical school, and the introduction of Lister's antiseptic surgical methods gained the hospital an international reputation.
