Glenn "Tiger" Ellison graduated from Denison after receiving recognition for his achievements in both football and track.  A three-time letterman in football, Ellison was named All-Buckeye Guard in 1931 and All-Ohio Guard in 1932. He was said to be ideally fit for the position he played and doubled as a linebacker on defense. He also lettered three years in track as a shot put and discus performer, and was a member of Denison’s 1933 Ohio Athletic Conference championship team. Ellison was also an active member of Denison’s Kappa Sigma fraternity.

Ellison, who earned a master’s degree in counseling, made his way to Middletown, Ohio in 1933 where he taught English and coached football at the high school level. Ellison developed the now-famous Run and Shoot football offense while in Middletown and was named Ohio Coach of the Year in 1961. He produced eight All-Ohio quarterbacks with his innovative offensive attack. He also served twice as President of the Ohio High School Football Coaches Association. Ellison ended his coaching career after 6 years at The Ohio State University, working under Denison teammate Woody Hayes.
