RACE: 36th Indianapolis 500

DATE: May 30, 1952

WINNER: Troy Ruttman

AVERAGE SPEED: 128.922 mph

WHAT HAPPENED: At just 22 years and 80 days, Ruttman became the youngest winner in Indianapolis 500 history. He still holds the record. Bill Vukovich led a race-high 150 laps and seemed poised to win the race until a busted steering linkage with nine laps left cost him the checkered flag.

NOTABLE: The Indy 500 introduced what would become a popular staple of the race, the rookie of the year. The award goes to the top first-year driver who has qualified or started the race. Art Cross finished fifth and was the first winner.
