In 1992 Valerie Sinason published Mental Handicap and the Human Condition, new approaches from the Tavistock Clinic. This work was very much rooted in the Trust’s strong history of working with developmental issues in child education services and by the 1990s the Trust were a leader in the field. By the end of the 1990’s we were clearly differentiating two groups: learning difficulties and autism. This led to two separate streams of work: one on autism chaired by Anne Alvarez and Sue Reid, and one on learning disabilities chaired by Valerie Sinason and Sheila Bichard. These two teams developed their expertise further and developed specialist training and education programmes, as well as a range of significant papers and publications, including: Autism and Personality (1999) by Anne Alvarez.
