In 1949 Bálint met Enid Flora Eichholz, who worked in the Tavistock Institute of Human Relations with a group of social workers and psychologists on the idea of investigating marital problems. Michael Balint became the leader of this group and together they developed what is now known as the "Balint group": a group of physicians sharing the problems of general practice, focussing on the responses of the doctors to their patients; the first group of practising physicians was established in 1950. Michael and Enid married in 1958. In 1968 Balint became president of the British Psychoanalytical Society.
