Robert Richard Chappuis played halfback and quarterback for the University of Michigan Wolverines in 1942, 1946, and 1947. His college years were interrupted by service in the U.S. Army Air Forces during World War II. Chappuis flew 21 missions as a radio operator and aerial gunner on B-25 bombers in the European Theater. His aircraft was shot down in February 1945 in the Lombardy region of Northern Italy. Chappuis parachuted from the plane before it crashed, and Italian partisans rescued him by hiding Chappuis and two other crew members for the final three months of the war.
