The health of nations: A review of the works of Edwin Chadwick, with a biographical dissertation by Benjamin Ward Richardson. 2 vols.

Chadwick may be said to have initiated the public health era. Largely through his efforts the Public Health Act 1848 came into existence in England. He was the greatest sanitarian of the 19th century; among other things he was responsible for the introduction of glazed earthenware pipes for drains. See also R. A. Lewis’s Edwin Chadwick and the public health movement, 1832-54, London, 1952.  Digital facsimile of the 1887 work from the Internet Archive at this link.
