The 11th International 500-Mile Sweepstakes Race was held at the Indianapolis Motor Speedway on Wednesday, May 30, 1923.
After winning previously in 1921, Tommy Milton became the first repeat winner of the Indianapolis 500. Howdy Wilcox (the 1919 winner) drove relief for Milton in laps 103-151. During the break, Milton had to have his hands bandaged due to blisters, and changed his shoes due to crimping of his toes.[1]
On lap 22, Tom Alley (driving Earl Cooper's entry) wrecked on the backstretch, going through the wall, and killed 16-year-old spectator Bert Shoup. Alley and two other spectators were injured. Taken from https://en.wikipedia.org/wiki/1923_Indianapolis_500.
Note: This was the last year with Carl Fisher as track president. James Allison took over in 1924.
