An outstanding swimmer and coach, he got his start at East High School. Along with Elwood Wooding and Pete Royer, the trio shattered distance records across the land. But Stewart at one time during his career held or shared 140 area pool, school and state records. During an outstanding career at Kent State he held Conference marks in the 200 and 400-yard freestyle. He later coached the Cuyahoga Falls YMCA team to a perfect 9-0 mark in the 1960-61 season. In the late '60s he came out of coaching retirement and led Akron U to its greatest season - eight straight victories and a 9-2 season.
