Date Published: January 21, 2010 Dr. John Z. Hearon Jr., 1920-2009 Sumter native was 2nd in world to earn doctorate in mathematical biology HEARON By BELTON WHITE Item Staff Writer bwhite@theitem.com A Sumter native who was the second person in the world to achieve a Ph.D. in mathematical biology died recently in Rockville, Md. Dr. John Zimmerman "Zim" Hearon Jr., who grew up in Sumter on North Washington Street, died on Dec. 28 after a long career as a scientist and an educator. He was 89. Hearon was a son of the late John Z. Hearon and Marie Bristow Hearon. His sister Sara Louise Manning still lives in town. His father was the owner of Hearon's Pharmacy on Main Street. Retired Sumter businessman I. Harby Moses, 89, lived near Hearon on Church Street and remembers fondly the time they spent together in high school and at The Citadel. "We had a good time here," Moses said Tuesday of their time growing up in Sumter. "We used to take the automobiles and run around with them. Once we got down to The Citadel, we wished we hadn't had such a good time." Moses said he, Hearon, Dr. William "Bill" Lemmon and Henry Barnett were all good friends while attending Sumter High School. "The Barnetts had a large automobile, and we would take that car and run it up and down the street," he said. "The police were after us most of the time. That was a long time ago." Even while at The Citadel, Moses said it was clear that Hearon was a brilliant man. "We got down there, and he started studying real hard; he did lot of studying," Moses said. Hearon remembered his time at The Citadel a little bit differently, according to an article published by South Carolina magazine in September 1950. "As an early undergraduate student, I was no great shakes. … Despite my intense interest in chemistry and mathematics, my freshman year looked rather hopeless to me and my parents. However, I fortunately managed to survive and improve," he told the magazine. "By the time I was a junior, I found things were going well, and I obtained a student assistantship in the Chemistry Department of the National Bureau of Standards during a summer vacation. It was shortly thereafter that I began to definitely get the idea that research was for me." After graduating from The Citadel in May 1941, Hearon enrolled at the University of Michigan, where he earned master's and doctorate degrees in biochemistry by 1944. By December 1944, he had entered the Army as a second lieutenant, and he was assigned as laboratory officer at Winter General Hospital in Topeka, Kan., until his discharge in February 1946. In 1947, Hearon enrolled at the University of Chicago, and on Dec. 19, 1949, he became only the second person in the world to earn a doctorate degree in mathematical biology. At that point in time, Chicago was the only university to have a committee on mathematical biology, according to the magazine. He went on to become an assistant professor of physiology at the university, then worked as senior mathematician at the Oak Ridge National Laboratory and as an analysis counselor to the technical director at the Naval Medical Research Institute. Hearon worked for the National Institutes of Health, joining the ranks in 1957 as chief of the National Institute of Arthritis, Diabetes, Digestive and Kidney Diseases Office of Mathematical Research. According to a newsletter from the institute, Hearon retired in 1981 as branch chief of the Mathematical Research Branch, a position he had held since 1961. "Most of his time was spent in the National Institutes of Health," Moses said. "He did real well with that place." After retiring, Hearon moved back to Sumter for a period of time. In his free time, Hearon was an avid equestrian, and he designed three-day event courses in Maryland. He is survived by two daughters, Kayce M. Connelly and Gayle Louise Blair, and two grandchildren. A graveside service was held Saturday at Sumter Cemetery. [1, 2] | |
