This paper considers the social forces leading to the establishment of pioneering public health education programs in the United States. Schools of Public Health emerged in the United States as the result of a confluence of factors, including the changing nature of higher education, the development of commerce and industry, the rise to prominence of the science of bacteriology, and the urbanization of the nation, all coupled with a pervasive spirit of utility and a desire to be, in a word, useful. Each line leading to the establishment of five public health institutions at the Massachusetts Institute of Technology, Harvard-M.I.T., Yale, Michigan, and Pennsylvania is explored.
