This text is a celebration of the work of Anne Alvarez, an enormously influential psychoanalytic psychotherapist whose work on autism and severe personality disorders in children has been important internationally. The book brings together assessment of the influence of Alvarez's work across a range of child psychotherapy and related areas, and evaluates how her ideas affect the most current developments in these areas. Included are contributions from renowned psychoanalysts and psychotherapists from around the world. The book should be of interest to child and adolescent psychotherapists in training and practice, and also to clinical psychologists, psychoanalysts and psychiatrists working with autistic/severely disturbed children.
