Traces the development of the sanitary and health problems of New York City from earliest Dutch times to the culmination of a nineteenth-century reform movement that produced the Metropolitan Health Act of 1866, the forerunner of the present New York City Department of Health. Professor Duffy shows the city's transition from a clean and healthy colonial settlement to an epidemic-ridden community in the eighteenth century, as the city outgrew its health and sanitation facilities. He describes the slow growth of a demand for adequate health laws in the mid-nineteenth century, leading to the establishment of the first permanent health agency in 1866.
