S. H. Foulkes (1898-1976) was born in Karlsruhe, and received his psychoanalytic training in the late 1920's in Vienna under Helene Deutsch. After some years in private practice he left Germany in 1933 and, after a brief stay in Geneva, settled in London at the invitation of Ernest Jones. During the 1940s he began to formulate the principles and methods of Group Analysis and Group-Analytical Psychotherapy. In 1952, with others, he founded the Group Analytic Society, and was still actively involved with teaching, lecturing and participation in group seminars until the time of his death.
E. J. Anthony was a psychoanalyst who trained in London where he began a distinguished career as a child psychotherapist and psychiatrist. He studied child development under Jean Piaget and, after leaving the Maudsley Hospital, occupied the Ittleson chair of child psychiatry, at Washington University School of Medicine, St. Louis. He is the author of many papers on Group Analysis, psychoanalysis, and child psychiatry. His collaboration with Foulkes, who became his training analyst, began at Northfield Hospital and in the early 1950s he became a founder member of the Group Analytic Society in 1952. Towards the end of his career he became Director of Psychotherapy at Chestnut Lodge, where he developed a program of group psychotherapy for adolescent inpatients.
