Born Margaret Schönberger on May 10, 1897, into a Jewish family in
Ödenburg, a small town near Vienna to Gustav Schönberger, an Austrian physician and president of the Jewish community, one of the notables of Ödenburg, and Eugenia Schönberger, née Wiener. She met the influential Hungarian psychoanalyst
Sándor Ferenczi, became fascinated by the concept of the
unconscious, and was encouraged to read
Sigmund Freud. In September 1916, she began Art History studies at the University of Budapest, but in January 1917 switched to the Medical School. Three semesters later she began medical training at the university of Munich, but was forced to leave because of
Antisemitism. In spring 1920 she transferred to the university of
Jena and it was there that she began to realize how important play and love were for infants in order for them to grow up mentally and physically healthy. After graduating
cum laude in 1922, she left for Vienna in order to get her license to practice medicine. There she turned from
pediatrics to
psychiatry and, in 1926, started her training
analysis with
Helene Deutsch. Seven years later, she was accepted as an
analyst. Working with children became her passion. She loved the way the children gave her their attention and showed their joy in cooperating with her. In 1936 she married Paul Mahler. Following the Nazis' rise to power, the couple moved to Britain and then, in 1938, to the United States. After receiving a
New York medical license, Margaret Mahler set up private practice in a basement and began to rebuild her clientele. She initially received a poor reception in New York, but found a welcoming analytic home in Philadelphia, invited to teach at the
Philadelphia Psychoanalytic Institute in 1950. She eventually travelled between New York and Philadelphia on the weekends and become the chair of the Philadelphia Institute's child division. In 1939 she met
Benjamin Spock and, after giving a child analysis seminar in 1940, she became senior teacher of child analysis. She joined the Institute of Human Development, the Educational Institute and the
New York Psychoanalytic Society. In 1948 she worked on clinical studies on Benign and Malignant Cases of Childhood
Psychosis.
Barnard College, at its 1980 commencement ceremonies, awarded her its highest honor, the
Barnard Medal of Distinction. Schönberger Mahler died on October 2, 1985. ==Work==
