From dragstrips and Daytona to the Indianapolis 500, virtually every driver in racing competition wears protective clothing and a helmet designed and produced by Simpson, a company founded and operated by Bill, a racer himself. Simpson went on to innovate other safety products, notably the Nomex fire suit, which Bill developed after friend (and early astronaut) Pete Conrad introduced him to the fire-retardant fabric then used by NASA. Bill was also the founder of Impact! Racing. He was inducted in to the Motorsports Hall of Fame of America in 2003.
