On this day in history, Aug. 19, 1909, the inaugural race occurred at the iconic Indianapolis Motor Speedway — now home of the world’s premier motor racing competition, the Indianapolis 500, as History.com pointed out.

"In that first five-mile race on Aug. 19, 1909, 12,000 spectators watched Austrian engineer Louis Schwitzer win with an average speed of 57.4 miles per hour," the same source noted.

Local businessmen Carl G. Fisher, James A. Allison, Arthur C. Newby and Frank H. Wheeler started the speedway.

It was originally created as a testing facility for Indiana’s growing automobile industry and was built on 328 acres of Midwest farmland five miles northwest of Indianapolis, Indiana, the same source said.

The rectangular 2½-mile track linked four turns, each exactly 440 yards from start to finish, by two long and two short straight sections, as History.com chronicled.

The Speedway’s debut was a little rocky, said the Indiana Motorcycle Preservation Society.

The original raceway oval featured a 2.5-mile distance and a packed gravel road — but the gravel was susceptible to potholes and dips, the same source recounted.

The speedway’s inaugural meets had tragic circumstances.

The first official Indy 500 was held on May 30, 1911. 

"Unfavorable conditions led to one of the drivers, Wilfred Bourque, flipping his vehicle. 

He and his mechanic, Harry Halcomb, sadly died," stated the Indiana Motorcycle Preservation Society.

The inaugural events at the speedway spanned three days.

The second day went off with no injuries or fatalities; however, the third day again encountered tragedy, as a racer’s tires blew and he spun into the audience. 

As a result, two spectators and another mechanic suffered fatal injuries and perished, according to the same source.

Following these accidents, caused in part by its rock-and-tar surface, the 2.5-mile track was paved with bricks in late 1909 — earning the nickname "the Brickyard," according to Indiana University at Indianapolis. 

The first official Indy 500 was held on May 30, 1911. 

Its 500-mile length and $27,000 prize purse were unlike anything seen in the auto racing world to that point; and the first Indy 500 featured 40 qualifying cars, according to the Henry Ford Museum.

Since 1911, the Indianapolis 500 has taken place every year, except for during the years 1917-18 and 1942-45, when the United States was involved in two world wars, History.com indicated.

With an average attendance of 400,000 spectators, the Indy 500 is the best-attended event in U.S. sports, cited the same source.

In 1936, asphalt was used for the first time to cover the rougher parts of the track, and by 1941 most of the track was paved, according to Motor Sport Magazine. 

The last of the speedway’s original bricks were covered in 1961, except for a three-foot line of bricks left exposed at the start-finish line as a nostalgic reminder of the track’s history, the same source noted.

Since its construction in 1909, the racetrack has become a National Historic Landmark and a legend in the world of auto racing, according to the Indianapolis Motor Speedway Museum.

First opening its doors in 1956, the Indianapolis Motor Speedway Museum currently boasts 37,500 sq. ft. of vintage cars, trophies, photographs, fine art, and other artifacts which capture the significance of motor sports. 

Each year, the venue welcomes more than 140,000 patrons, who visit Racing Capital of the World, the same source stated.
