James D. Hartzell '65 is one of the most decorated swimmers from an era when North Central College dominated the sport. Hartzell won 10 National Association of Intercollegiate Athletics (NAIA) swimming titles as a Cardinal and was a member of the 1962 and 1963 NAIA national championship squads.

He is the only NAIA swimmer ever to win the 200-yard backstroke in four consecutive years (1962-65), and one of only three athletes to win the 100-yard backstroke three times (1963-65). He was a key member of the back-to-back-to-back 400-yard medley relay squads that captured national titles for North Central (1962-64) and set numerous NAIA records along the way. Hartzell was also a two-time captain for the Cardinals.
