Harry Stack Sullivan

Herbert "Harry" Stack Sullivan (February 21, 1892, Norwich, New York – January 14, 1949, Paris, France) was an American Neo-Freudian psychiatrist and psychoanalyst who held that the personality lives in, and has his or her being in, a complex of interpersonal relations. Having studied therapists Sigmund Freud, Adolf Meyer, and William Alanson White, he devoted years of clinical and research work to helping people with psychotic illness.

Sullivan was a child of Irish immigrants and grew up in the then anti-Roman Catholic town of Norwich, New York, resulting in a social isolation which may have inspired his later interest in psychiatry. He attended the Smyrna Union School, then spent two years at Cornell University from 1909, receiving his medical degree in Chicago College of Medicine and Surgery in 1917.

Along with Clara Thompson, Karen Horney, Erich Fromm, Otto Allen Will, Jr., Erik H. Erikson, and Frieda Fromm-Reichmann, Sullivan laid the groundwork for understanding the individual based on the network of relationships in which he or she is enmeshed. He developed a theory of psychiatry based on interpersonal relationships where cultural forces are largely responsible for mental illnesses (see also social psychiatry). In his words, one must pay attention to the "interactional", not the "intrapsychic". This search for satisfaction via personal involvement with others led Sullivan to characterize loneliness as the most painful of human experiences. He also extended the Freudian psychoanalysis to the treatment of patients with severe mental disorders, particularly schizophrenia.
