a further world war, which could bring bombing of cities, evacuation of children and the shocks of loss and bereavement. Post-war history After the Second World War, the Tavistock Clinic benefited from the Northfield Hospital experience and from the arrival of talented professionals from Europe, many fleeing Nazi persecution. In 1948 it became a leading clinic within the newly created National Health Service. At this point its education and training services were managed separately by the Tavistock Institute for Medical Psychology, which was also the umbrella for the Tavistock Institute, involved in social action research and thinking about group relations and organisational dynamics, and for work with marital couples. The clinic was managed on a democratic model by a professional committee and developed further its distinct focus on multi-disciplinary and community-centred work. Children and young people New developments in child and adolescent mental health were particularly fruitful in the immediate post-war period. In 1948 the creation of the children's department supported the development of training in child and adolescent psychotherapy. Dr John Bowlby supported this new training and naturalistic infant observation. He also developed Attachment Theory. Husband and wife clinicians James Robertson and Joyce Robertson showed in their film work the impact of separation in temporary substitute care on young children for example, when their parent was admitted to hospital. The Tavistock Clinic opened its Adolescent Department in 1959, recognising the distinctive developmental needs and difficulties of younger and older adolescents. In 1967 it absorbed the London Child Guidance Clinic, founded in 1929. In 1989 the Tavistock established the Gender Identity Development Service (GIDS), a highly specialised clinic for young people presenting with difficulties with their gender identity. In July 2022, following a critical independent review from Dr Hilary Cass, it was announced that this service would be discontinued and replaced with regional clinics providing a more "holistic" approach. Training in education By the 1960s The Tavistock Clinic was also providing both 1-year and 4-year professional training courses in educational psychology, the latter embracing a teacher training element through Leicester University School of Education. For a number of years the senior tutor and principal psychologist for these courses was Irene Caspari who did much to promote the concept and practice of Educational therapy. In the 1970s systemic psychotherapy became the Tavistock Clinic's newest professional training. Applications of the clinical ideas and skills of its multidisciplinary clinicians are at the heart
