It is well known that psychoanalysis has over the years had a significant impact on the education of children with mental health problems. Its contribution to the theory and practice of mainstream education is less well documented. This paper gives an account of the five-year (1924–1929) history of the Malting House School in Cambridge. The school was financed by Geoffrey Pyke and headed by Susan Isaacs, a teacher, psychologist and early member of the British Psychoanalytic Society, who became a leading protagonist of the ideas of Melanie Klein. The physical structure, organisation, philosophy and curriculum of the school are described. Although the school was only in existence for five years, through the writings and teaching of Susan Isaacs it had a lasting impact on early years education.
