Maudsley Hospital
The Maudsley Hospital is a British psychiatric hospital in South London. The Maudsley is the largest mental health training institution in the country. The hospital's trust describes itself as a world leader in research and also works in partnership with the Institute of Psychiatry, King’s College London.

The hospital is part of the South London and Maudsley NHS Foundation Trust (SLaM), provider of an extensive portfolio of mental health services in the United Kingdom, and a research institute working in partnership with the Institute of Psychiatry, King’s College London. The Maudsley dates from 1907, when Dr Henry Maudsley offered London County Council £30,000 (subsequently increased to £40,000) to help found a new mental hospital that would: be exclusively for early and acute cases, have an out-patients' clinic, provide for teaching and research. World War I intervened and the Hospital functioned as a war hospital, not actually opening as a mental health resource until 1923. It remains notable that a specific Act of Parliament had to be obtained (1915) to allow the institution to accept voluntary patients. The Maudsley was returned to the control of London County Council some time after the First World War, and was finally opened in February 1923. Its nursing staff comprised a matron, assistant matron, six sisters and 19 staff nurses with at least three years' general hospital training, supported by 23 probationers and 12 male nurses. The Maudsley had a good reputation for training nurses and some applicants even travelled overseas to train there. A report (held at Bethlem's Archives & Museum) from a nurse who trained at the Maudsley shows some of the work of a new trainee: "Apart from observation and simple treatment, nurses are trained in special investigations and therapy. They carry out many of the routine psychometric tests, help as technicians in the ward laboratories, and are instructors in occupational therapy". The 1920s and 30s saw a rapid growth in the number of patients treated at the Maudsley. Originally, there was no provision for the treatment of children and the rapid growth in this patient population was unforeseen. In 1928, a child guidance clinic was set up under the directorship of Dr William Moodie, the deputy medical superintendent. The Children's Department was promoted as an example of the value of teamwork: 'psychiatrists to diagnose and to prescribe, psychologists for mental testing, social workers to deal with the environmental side and voluntary workers to observe the activities of the children in the play room'. The demand for these services led to the construction of a dedicated building where children were seen as outpatients. In 1947 a dedicated inpatient unit for children was opened.

Research and teaching
Henry Maudsley was committed to psychiatric research, and the hospital incorporated the Central Pathological Laboratory transferred from Claybury Asylum. Although the hospital initially struggled to secure funding from the Medical Research Council, in 1938, the Rockefeller Foundation made a substantial award to support research and education and the Maudsley has been an internationally renowned centre for research ever since. The Maudsley Hospital Medical School was established in 1924 and became a well respected teaching centre. In 1932, Professor Edward Mapother, the first medical superintendent, described the Maudsley as "the main postgraduate school of mental medicine in England." This medical school later became the Institute of Psychiatry which is part of King's College London. Throughout the 20th Century, the Maudsley pioneered the development of new treatments. Breakthroughs included the introduction of clinical neuroscience in the 1950s which was partly led by Denis Hill, a senior lecturer at the Maudsley and the Institute of Psychiatry (IoP), and the use of group talking therapies which is still practiced today. The growth of the Maudsley led to an on-going building programme. In 1933, a purpose-built outpatient department was added, two years after the completion of a secure unit. At the outbreak of the Second World War, and the threat of air-raids, the Maudsley closed and staff dispersed to two locations: a temporary hospital at Mill Hill School in north London and Belmont Hospital in Sutton, Surrey. Staff returned to the Maudsley site in 1945 and three years later the Maudsley joined up with the Bethlem Royal Hospital to become partners in the newly established NHS. This partnership saw the introduction of more community-based services and a gradual expansion of the south London catchment area, to become South London and Maudsley NHS Foundation Trust in 2006. Sharing the Maudsley site is the Institute of Psychiatry, a postgraduate institute of the University of London and, since August 1997, a school of King's College London. It is the only postgraduate institution in the UK that is devoted to the study and practice of psychiatry and related disciplines.

Current hospital
The Maudsley continues to provide in-patient and community mental health care to local people in Southwark and Lambeth and nationally across the UK. Sharing a site with the Institute of Psychiatry at King's College London it is also a contributor to both psychiatric research and the training of mental health care staff. As part of the South London and Maudsley NHS Foundation Trust (SLaM) it also has close links with Bethlem Royal Hospital - the original "Bedlam".

Academic Health Sciences Centre
SLaM is part of King's Health Partners Academic Health Sciences Centre (AHSC) - in partnership with King's College London, Guy's and St Thomas' NHS Foundation Trust and King's College Hospital NHS Foundation Trust. King's Health Partners aims to promote health in mind and body (see An AHSC is one of several terms which are used to describe an organisation which delivers both healthcare to patients and health-related science and research, usually with a well developed teaching and education role as well. This type of organisation is fairly common amongst the leading hospitals and universities around the world. There are currently five AHSCs in the U.K.

Biomedical Research Centre
The Trust manages the U.K’s only Specialist Biomedical Research Centres in partnership with the Institute of Psychiatry, King’s College London. The Centre, which is based on the Maudsley Hospital campus, is funded by the National Institute for Health Research (NIHR). Its aim is to speed up the pace that latest medical research findings are turned into improved clinical care and services. The team at the Centre are working towards 'personalised medicine' - developing treatments based on individual need. The aim is to diagnose illness more effectively and much earlier, assess which treatments will work best for an individual and then tailor the care they receive accordingly, so that they get better more quickly.
