Bowser was born in Ligonier, Pennsylvania and attended Johnstown High School, where he played high school football. He left high school as a senior, in April 1918, in order to enlist in the Army. From May 1918 to April 1919, he served overseas in the Ambulance Corps.[2]
Upon graduation from Pittsburgh, Bowser served as an assistant at Grove City College under Guy "Chalky" Williamson. After the 1923 season, Williamson left for the Pittsburgh football staff, and Bowser took over as Grove City head coach. The Grove City Crimson went 3–5–1 in his first season, but improved in the next two years. In 1925, they posted a 7–1 record, with the sole loss coming against West Virginia. The next season, Grove City finished with a perfect 7–0 mark, including a 3–0 victory against Bo McMillin's Geneva College which defeated Harvard.[2]
In 1927, Bowser returned to Pittsburgh, to aid head coach Jock Sutherland as the ends, backs, and centers mentor. In 1930, Bowser took over as the head coach of Bowdoin College, a post he held through 1934. He was replaced by Adam Walsh, former captain of the Notre Dame Fighting Irish. Bowser then became assistant at Pitt again in 1935, and in 1937, he was promoted to the chief assistant position.[2]
After that season, he left the coaching ranks to work as an insurance agent in Pittsburgh.[4] In 1939, Bowser returned to Pittsburgh as its head coach, and served in that position through the 1942 season. He resigned his post in January 1943 to take a commission in the United States Navy during World War II.[5] He was replaced by T formation innovator Clark Shaughnessy.[5]
