History of Indianapolis Motor Speedway

The Indianapolis Motor Speedway complex was built in 1909 as a gravel-and-tar track and hosted a smattering of small events before the promoters decided to focus on just one major event. The track was then paved with 3.2 million bricks, urged by principal owner Carl G. Fisher after several deaths related to the unsteady racing surface. The creation of a 500 mile (805 km) race allowed the track to rapidly acquire a privileged status for automobile races. The first "500" was held at the Speedway on Memorial Day, May 30, 1911, with Ray Harroun piloting a Marmon "Wasp" — outfitted with his invention, the rear view mirror. Harroun was declared the winner, although Ralph Mulford protested the official result. 80,200 spectators paid $1 admission, and an annual tradition had been established. Many considered Harroun to be a hazard during the race, as he was the only driver in the race driving without a riding mechanic, who checked the oil pressure and let the driver know when traffic was coming.
