[1][2] Anthony was recruited in England in 1958 to hold the world’s first endowed chair in Child Psychiatry, the Blanche F. Ittleson Professorship at Washington University in St. Louis where he conducted most of his longitudinal research.
His collaboration with Foulkes, who became his training analyst, began at Northfield Military Hospital, and in the 1950s he became a founder member of the Group Analytic Society.
He was a protégé and collaborator with Jean Piaget, Anna Freud, Erik Erikson, John Bowlby, and Sir Aubrey Lewis who, throughout his early career, introduced Anthony to international and cultural aspects of child development.
Later, he was transferred to Hong Kong as chief medical officer for Southeast Asia and was charged with setting up day-care centers for Japanese children who survived the atomic bombings of Hiroshima and Nagasaki.
He was later a member of the Royal College of Psychiatry and his multiple lectureships included a standing appointment at the London School of Economics.
As the president of AACAP, he continued his commitment to international collaboration, with both a joint meeting in Mexico, and leading two large groups to China on the brink of its opening to the West.
His appointment to the Work Group on Consumer Issues led to the development of AACAP’s Facts for Families, which have been translated into multiple languages.
