Char Duff earned a bachelor's degree with honors in physical education from the University of Wisconsin in 1948. After teaching at the high school and collegiate levels, Char went on to earn a master's degree at the University of Michigan in 1956. That same year Char began 34 years of dedicated service at Albion College as a faculty member and as field hockey and women's tennis coach.
Char was one of the founders of the Ann Arbor Field Hockey Association and the Michigan College Field Hockey Association, serving both organizations as president for many years. She also served the Michigan Association for Health, Physical Education, and Recreation as president and as the assembly representative to the MAHPER. In 1977 Char was awarded the Distinguished Honor Award by the MAHPER. Char served on numerous other women's athletic association boards and most recently has been a member of the NCAA's National Field Hockey Committee, serving as the chair for the Great Lakes Field Hockey Committee. She has been a driving force in women's athletics for the State of Michigan and nationally.
At the helm of the Britons, Char's career wins in field hockey rank her first among all MIAA coaches in that sport. From 1976 to 1980, the field hockey teams captured five straight league titles.
In May 1990, Char retired as professor and chairman of physical education and as a coach, but she continues to be involved in the community and with Albion alumni.
