He earned his Bachelor of Science in mathematics and physics from The Citadel (1959), his Ph.D in mathematics from Tulane University (1963),^{[1]} and his J.D. from the University of Georgia School of Law (1976) in Athens, Georgia. After earning his J.D. he practiced law in Athens, before returning to the mathematics faculty. He retired in 2002. He died at 65, after suffering from a brain tumor.^{[2]}
