Charles S. Tuesday *55

After serving in the Army from 1946 to 1948, Tuesday received a bachelor’s degree from Hamilton College in 1951. He then earned a Ph.D. in chemistry from Princeton in 1955. Early in his career, he was known for his study of atmospheric chemistry that resulted in petrochemical smog. He built the world’s most advanced man-sized atmospheric-smog chamber, and defined the reactions between hydrocarbons and nitrogen oxides that produce ozone and eye irritation.

Tuesday also was heavily involved in General Motors’ efforts to develop and implement the catalytic converter and unleaded gasoline. During his 37-year career at GM, he headed the fuels and lubricants, environmental science, and physical chemistry departments. In 1992, he retired as executive director of materials sciences.  

He was a fellow of the American Associa- tion for the Advancement of Science and received an American Chemical Society award for his contributions to chemistry related to the auto industry.

Tuesday is survived by Jean, his wife of 55 years; three children; and five grandchildren.
