Friday 30th May 1924
Lora Lawrence Corum started the Indianapolis 500 in the #15 entry, and was relieved during the race by Joe Boyer. Boyer drove the Duesenburg to victory, and both drivers were credited as “co-winners” for the 1924 race. Boyer led the first lap of the race in his original #9 entry. After Boyer got out of the car and took over the #15, the #9 entry continued in the race, taken over by Ernie Ansterburg, Corum, and later Thane Houser. Houser crashed the car after 176 laps, and Boyer’s original car was credited with 18th place.
