Lowell S. Levin (1927-2019) was Emeritus Professor at Yale University. At the School of Public Health, Professor Levin developed innovative educational programs, including founding the school’s global health division. He was committed to health promotion, and pioneered the citizen participation movement, which focused on health communication and the social and behavioral factors affecting health. Subsequently, he brought attention to the role of non-professional resources in strengthening personal capacity for health and well-being, primarily via self-care, and pressed for improvement in the quality of medical care. For over thirty-five years, he served as an advisor to the World Health Organization’s European Region, as well as to NGOs in Europe, Latin America, the Commonwealth Caribbean and the United States. In European countries, he worked to develop cross-departmental collaborations at the national level to improve the impact on health of diverse public policies in such areas as the environment, agriculture, employment, education, communications and tourism. Clarifying the links between poverty, social inequity and health, Professor Levin’s work increased policy makers’ awareness of the need to make “healthy public policies” through intersectoral action designed to optimize the benefits of collaborative health interventions in effective and sustainable ways.Alfred H.
