The Maudsley Hospital celebrated its 100th year anniversary on 31 January 2023. Maudsley Hospital had first been requisitioned by the War Office before its completion in 1915 to deal with the military casualties of the First World War. The organisation has changed in many ways over the last century, but thanks to the staff and partners, Henry Maudsley’s vision, of a hospital in an urban centre where mental healthcare, teaching and research would come together, endures.
