He served in the Pacific Theatre and was discharged in 1946 with the rank of master sergeant. He returned to Harvard that fall and was captain of the 1946 Harvard Crimson football team. He scored the game–winning touchdown in the season opener against UConn. One of his teammates that season was his younger brother, Kenneth O'Donnell.
