John Gill (born 1937) is an American mathematician who has achieved recognition for his rock-climbing. He is considered the Father of Modern Bouldering by many climbers.

As a child, Gill lived in several Southern cities, including Atlanta, Georgia, where he graduated from Bass High School [1] in 1954 and attended Georgia Tech 1954-1956. He graduated from the University of Georgia with a degree in mathematics in 1958, and entered the USAF as a second lieutenant. He attended a special graduate meteorology program at the University of Chicago 1958-1959, then was assigned to Glasgow AFB, Montana, until 1962. He resigned from the USAF Reserves as a captain several years later. After obtaining an MA in mathematics from the University of Alabama in 1964, Gill became an instructor at Murray State University 1964-1967. In 1967 he enrolled as a graduate student at Colorado State University, and received his PhD in classical complex analysis in 1971. In 2000, Gill retired as professor of mathematics from the University of Southern Colorado. During his career as a college teacher, in his spare time he wrote and published approximately thirty individually authored research papers in the analytic theory of continued fractions and related topics. He also started a minor mathematical journal entitled Communications in the Analytic Theory of Continued Fractions with John McCabe of St Andrews University.[2],[3]
