1897 – 1985
Margaret Schönberger Mahler, a pioneering child analyst, began her career in Vienna but made her most important discoveries in the United States. She became a leading authority on the mother-child relationship and the separation-individuation process, which she examined in her best-known work, The Psychological Birth of the Human Infant.
Born on May 10, 1897, in Sopron, Hungary, she spoke German to her mother, Eugenia (Wiener) Schönberger, and Hungarian to her father, Gusztav Schönberger (originally Fertoszentmiklos). Resentful of her beautiful younger sister, who resembled their mother, Margaret decided to follow in her adored father’s footsteps by becoming a physician. At sixteen, she left Sopron for Budapest, where she began her medical studies in 1917. After encountering antisemitism and discrimination as a foreign student in Munich, Jena, and Heidelberg after World War I, she received her doctorate from the University of Jena in 1922 and then moved to Vienna, where she obtained her medical license and established a private pediatric practice.
Introduced to psychoanalytic theories by Sandor Ferenczi in Budapest, she became affiliated with the Vienna Psychoanalytic Society and underwent training analysis, first with Helene Deutsch and later with August Aichhorn and Willi Hoffer. Having worked as an assistant in two pediatric clinics, she became a municipal youth and welfare physician and conducted research on juvenile delinquents in Aichhorn’s child guidance centers. In 1938, after the anschluss, she left Vienna for England together with her husband, Paul Mahler, a Jewish chemist whom she had married two years previously. After a brief stay in London, they immigrated to the United States.
Settling in New York, Mahler passed her state medical boards in 1939 and became a member of the New York Psychoanalytic Society. In the 1940s, she worked as an unsalaried consultant at the New York State Psychiatric Institute and Mount Sinai Hospital and taught psychiatry at Columbia University before joining the faculty of the Albert Einstein College of Medicine in 1950. Commuting from New York to Philadelphia on weekends, she directed the child analysis training program of the Philadelphia Psychoanalytic Institute. In 1956, she established a therapeutic nursery program for psychotic children at Einstein. In 1962, with a grant from the National Institute of Mental Health, she created the Masters Child Center, a laboratory for the study of the interaction between mothers and their children under three.
Margaret Mahler was not an observant Jew; her Jewish identity was shaped by the antisemitism she experienced in her youth and her mother’s death during the Holocaust. Her last wish before her death on October 2, 1985, was that her ashes, together with those of her husband, be interred in the Jewish cemetery in Sopron, alongside her father’s grave.
For almost forty years, Margaret S. Mahler was actively involved in teaching, clinical practice, and research in the United States. She published several books and over a hundred scholarly papers. Among the sizable group of emigrés from Nazi Europe who helped shape American psychoanalysis, she stands out as one of the most highly respected and honored for her major contributions to the development of child psychology.
