In 1964 the Lowell Institute sponsored a series of lectures at the Massachusetts General Hospital on "The Hospital's Responsibility to the Community." During the same period The New England Journal of Medicine published a series of articles on "The Social and Organizational Aspects of Medical Care." These concurrent explorations into the social, cultural, economic, and organizational aspects of medical and institutional practice are in the long tradition of inquiry that we have come to expect of The New England Journal and the "M.G.H." John H. Knowles, MD, General Director of the Massachusetts General Hospital, has gathered the Lowell Lectures into a provocative and timely volume, Hospitals, Doctors, and the Public Interest. The 15 authors have been drawn principally from the ranks of hospital and medical care administrators and Harvard professors of various medical specialties, who in their own careers have demonstrated the facility to combine practical accomplishment with theoretical conception.
