193942, 1946: The helmet was now officially required in college football. The Riddle Company in Chicago invented and patented the first plastic helmet with a new revolutionary three-strap, six-point adjustable suspension that could be raised or lowered for a better fit. But when WWII broke out, plastics were conserved for the war effort. The Riddle Company also developed a chinstrap worn directly on the chin rather than under the jaw. It attached to one side with a snap. Marshall's helmets at this time were a white painted leather. Basic colors helped incorporate the helmet into the rest of the team uniform. Michigan's winged helmet is one of the most recognized icons in college sports. The design simply followed the helmet's stitched leather structure. Using colors also allowed quarterbacks to better see their receivers downfield. (Note: WWII, no games played from 1943-45)
