Richards, Ellen H. (Ellen Henrietta), 1842-1911. Conservation by sanitation; air and water supply; disposal of waste (including a laboratory guide for sanitary engineers) by Ellen H. Richards. New York. J. Wiley & sons; [etc., etc.] 1911. xii, 305 p. front., illus., fold. map, tables. 24 cm. text txt rdacontent unmediated n rdamedia volume nc rdacarrier Ellen Henrietta Swallow Richards was a chemist on the faculty of the Massachusetts Institute of Technology, the major founder of the discipline of home economics, and a pioneer in opening scientific education and the scientific professions to women. She described herself as a "human ecologist," representing the effort to apply the principles of the conservation movement directly to human life through improvement of the man-made--especially the urban--environment. Though limited in scope, this attempt to foster what was called "human conservation" anticipates the later concern with environmental pollution which would ultimately merge with concern for the conservation of the natural world to create the late-twentieth-century environmental movement. This book defines the challenges of "sanitation"--air quality, waste disposal, and (especially) water pollution--in terms of both human and natural-resources conservation, reflecting the era's vast confidence in the capacity of rationally- and humanely-applied technology to solve social problems, including those of conservation.
