William Zeidler Fluck died peacefully Friday, Jan. 25, 2008. William enrolled in the University of Wisconsin-School of Engineering in 1931 and earned bachelor’s and master’s degrees in chemical engineering with graduate work in the areas of hydraulic and sanitary engineering and public health. After graduation in June 1937 he became one of the original staff of three men who organized the Industrial Hygiene Unit of the Wisconsin State Board of Health, which was the beginning of his 35-year career in industrial hygiene. William traveled throughout the state of Wisconsin studying possible health hazards in the milk canning industry, granite quarries, foundries and schoolrooms. In 1943 he enlisted as an industrial hygiene engineer in the Army Air Force and worked on such diverse problems as radiation hazards, sewage and industrial waste management, and mosquito control. He then returned to Madison as chief industrial engineer for the Wisconsin Board of Health from 1946 to 1950.
