Of special interest is the diary of his 1961 Medical Ecology Mission to the USSR. This group diary/report was written by various members of the mission. Lee's article on this trip, "The Organization of Health Services in the Soviet Union" published in Stanford Medical Bulletin, can be found in the Articles Subseries. It also includes a copy of Lee's 1955 master's thesis: The Influence of Varying Concentrations of Sodium Chloride on the Rate of Water Absorption form the Upper Part of the Gastro-Intestinal Tract of Normal Human Subjects submitted in April 1955 to the Faculty of the Graduate school of the University of Minnesota. Also found in this subseries are correspondence and minutes pertaining to Lee's involvement with the formation of a medical issues discussion group first called the Committee on Health and Medical Care for California in 1962 and later referred to as the Chowder and Marching Society; and a 1961 symposium on cardiovascular disease.
