Charles M. Judson begins his interview with a description of his father and the effect that his father had on his own interest in science. His father was a chief metrologist at the National Bureau of Standards and enjoyed taking young Judson on Sunday walks, describing the scientific aspects of the world around them as they went along. Judson’s father also had a strong influence on his academic career, arranging his high school curriculum to best suit his educational needs. Judson describes himself as a tall, “clumsy” young man and a “disorganized” student who was saved from anonymity by his prowess in basketball. However, in tenth grade, when a heart murmur prevented him from continuing with sports, Judson began to focus on his academics. Judson received a partial scholarship at Swarthmore College and began his undergraduate studies as a physics major. After struggling with the mathematics involved in physics, Judson switched to chemistry and received high honors at Swarthmore. In 1940, Judson began his graduate work in chemistry at the University of Pennsylvania, working on the dissociation constants of substituted phenols. However, in 1942, World War II erupted, and Judson left the University of Pennsylvania to work on the Manhattan Project. Judson was put to work studying the absorption of regular uranyl nitrate versus concentration as a possible method of controlling the proposed process. In 1945, with the end of the war, Judson returned to the University of Pennsylvania, and in 1947 he finished his thesis and accepted a job at American Cyanamid Corporation, where he worked on radioactive isotopes and in industrial applications. Judson left American Cyanamid in 1962 and took a position as manager of the Analytical Developments Group at Consolidated Engineering Corporation. After seven years at CEC, Judson left and worked at the University of Southern California’s School of Pharmacy. In 1980 Judson settled in a laboratory position at the University of Kansas, where he stayed until retirement. Judson concludes his interview with a discussion of some of the scientific instruments in his home.
