In 1907, Maudsley collaborated with Frederick Mott, a neuropathologist, to make an offer to London County Council to found a new Maudsley Hospital, for which Maudsley donated £30,000, with the council finding another £30,000 plus. This was to be a new mental hospital that would treat early and acute cases and have an out-patient clinic. The hospital also housed teaching and research. The buildings were ready in 1915, temporarily used for war veterans, and officially opened in 1923. A special Act of Parliament had made voluntary treatment there financially possible.
