Kraus, Ezra J. Papers 1915-1947

http://www.lib.uchicago.edu/e/scrc/findingaids/view.php?eadid=ICU.SPCL.EJKRAUS

Ezra J. Kraus (1885-1960), botanist and horticulturist, served as a professor in the University of Chicago's Department of Botany from 1927-1948, and as chair of the department from 1934-1947. His research in plant physiology focused on nutrition in relation to development and behavior, established the principle of the carbohydrate-nitrogen growth ratio in plants, and pioneered the use of synthetic substances in the regulation of plant growth. During World War II, Kraus worked with the National Research Council to direct research and development of herbicides for use in biological warfare. This collection documents Ezra J. Kraus's research in agriculture and horticulture, as well as his work as an administrator at the University of Chicago, the Bureau of Plant Industry and the National Research Council.
