Joe Boyer is the only person to win the Indianapolis 500 and APBA Gold Cup. Boyer gained fame as a member of the Frontenac and Duesenberg teams from 1916 to 1924. If Boyer didn’t win, it was often because his cars failed while upfront. In 1921 he was leading teammate Jimmy Murphy in the French Grand Prix when a connecting rod failed 12 laps from the end. His 1924 Indy 500 win came after he took over teammate L.L. Corum’s car on lap 109. Car owner Fred Duesenberg said, “Put that ship out front or burn it up.” He moved the car from fourth to first in 70 laps to take the checker, becoming the first official "relief" driver credited with the win in the 500. Tragically, he was killed three months later while racing wheel-to-wheel with Murphy at the Altoona, PA board track. Murphy was killed a week later.
