Actually the Indianapolis track is a bit older, having been built in 1909, originally with a loose surface. The point was to provide a place for automakers to conduct testing, when their products were proving too quick to test on public roads. It was apparent quickly that a more substantial surface was the smart way to go and 3.2 million bricks were laid down. The track is that famous 2.5-mile round-corner rectangle, its shape set by the size of the 328 acres of farmland on which it was built.
After several tries at racing events, it was decided to try a major extravaganza and 500 miles was set as the distance. That's when Chevrolet enters – rather Chevrolets as all three brothers would eventually compete in the event.
Arthur was in the first race's 40-car field driving a Buick. Louis drove in 1915 and 1919, the last year joined by younger brother Gaston. The next year, Gaston won in a Monroe-Frontenac and was the first driver to make the distance on one set of tires. Sadly, Gaston died the following November in a race on the Beverly Hills board track, but had earned enough points to win the AAA title, the equivalent of being the Indycar champ today.
After a period when Chevrolet's main involvement at Indy was with pace cars, it went back to racing between 1986-1993 and then 2002-2005 with engines and in that period won 104 races and seven Indy 500s.
