ABSTRACT
The dominant theme throughout my 50 years as a psychiatrist has been my active search for new concepts, service models, and techniques to prevent psychosocial disorder in a population. In fulfilling this mission, I have become accustomed to crossing boundaries: (a) spatial boundaries, when I went out of the mental hospitals, in which I, like most psychiatrists, worked fifty years ago, to establish outpatient clinics in the community, and then to open psychiatric departments in general hospitals—a revolutionary step in those days—and later to offer mental health consultation in schools and public health centers; and (b) boundaries between the professional disciplines and between professional domains, involving my reaching out to recruit other professions in carrying out my own professional mission.
