In 1839 the Council of King's College London was persuaded by Robert Bentley Todd (1809-1860), a physician at the College, to lease a disused workhouse in Portugal Street near Lincoln's Inn Fields and the Royal College of Surgeons, and convert it for use as a hospital. This was the first King's College Hospital and it opened in 1840. Its purpose was to provide King's College medical students with a place in the near vicinity of the College where they could receive instruction by their own professors. The Council of King's College London became the supreme governing body of the Hospital, largely through a Board of Governors, with the right to appoint all medical staff. A Committee of Management undertook the day to day administration and appointed lay officers. The Sisterhood of St John the Evangelist provided all nursing and catering for the Hospital between 1856 and 1885. A second hospital was opened in 1861 on the site of the first extended hospital. A Medical Board was subsequently established at the College to oversee the academic work and teaching. By 1900, the changed nature of the surrounding area of the Hospital and the fact that about a third of patient admissions came from South London, led to a Special Court of the Governors, in 1903, adopting a proposal to move King's College Hospital south of the river Thames. In 1904 an Act of Parliament was obtained to remove the Hospital to Denmark Hill, on land purchased and presented to the Governors by Hon William Frederick Danvers Smith, later Lord Hambleden. A foundation stone was laid in 1909; that year King's College London was incorporated into the University of London and the Hospital established as a separate legal entity. At the same time the Committee of Management took over responsibility for teaching in the School of Advanced Medical Studies, bringing into existence King's College Hospital Medical School. The Faculty of Medical Science remained at the College providing pre-clinical training, while the Hospital Medical School provided clinical training, the latter being recognised as a School of Medicine by the University of London. The new Hospital was opened in 1913. From 1914 to 1919, the Hospital became the Fourth London General Military Hospital and a large part of it was taken over for military uses. In 1923 a Dental School and Hospital was established within the Hospital. In July 1948 the National Health Service Act came into operation. A King's College Hospital Group was recognised as a teaching group managed by a Board of Governors and responsible to the Minister of Health. In 1948 the King's College Hospital Group consisted of King's College Hospital, Royal Eye Hospital, Belgrave Hospital for Children, Belgrave Recovery Home, and Baldwin Brown Recovery Home. From 1966 the King's Group consisted of King's College Hospital, Belgrave Hospital for Children, Belgrave Recovery Home, Baldwin Brown Recovery Home, Dulwich Hospital, St Giles Hospital, and St Francis Hospital. In 1974, due to the reorganisation of the National Health Service, the Board of Governors of King's College Hospital Group was disbanded, and replaced by a District Management Team. The King's Health District (Teaching) was thus formed as one of the four Districts in the Lambeth Southwark and Lewisham Area Health Authority (Teaching). The second reorganisation of the National Health Service took place in April 1982, resulting in the King's Health District (Teaching) becoming a new Health Authority, the Camberwell District Health Authority. In 1983 King's College Hospital Medical School was reunited with the College to form King's College School of Medicine and Dentistry. The Hospital came under the management of the King's Heathcare Trust in 1993. The United Medical and Dental Schools (UMDS) of Guy's and St Thomas's Hospitals merged with King's College London in 1998, creating the Guy's, King's and St Thomas's School of Medicine.
