Melvin Eugene "Tony" Bettenhausen was an American racing driver known primarily for his open-wheel career. He twice won the National Championship, doing so in 1951 and 1958. He also competed in stock cars, winning under AAA and USAC sanction.
Gaston Louis Chevrolet was an American racing driver and automobile manufacturer. He was the winner of both the Indianapolis 500 and the American National Championship in 1920.
The 1915 Grand Prix season saw Grand Prix motor racing continue in the United States. Racing was suspended in Europe due to the outbreak of World War I. The American Grand Prize was held in San Francisco for the first time, in conjunction with the Panama–Pacific International Exposition. Several of the latest European cars had been imported to the USA before the war started. Briton Dario Resta had a Peugeot and Ralph DePalma raced one of the Mercedes GPs. While Resta won both races at San Francisco and DePalma won the Indianapolis 500, just ahead of Resta it was Earl Cooper, running a Stutz, whose consistency gave him the unofficial AAA national championship.
The 1916 Grand Prix season saw Grand Prix motor racing continue in the United States. Racing was suspended in Europe due to the World War I engulfing the continent. Once again European cars dominated Indianapolis with victory going to Briton Dario Resta in a Peugeot. With the organisers wanting to appeal to the spectators, this was the only year that the race was scheduled for a shorter length – to run only 300 miles. The Vanderbilt Cup and the American Grand Prize returned to Santa Monica, California at the end of the year. Resta repeated his victory from the year before, winning the Vanderbilt Cup. Then when he retired in the Grand Prize it was Howdy Wilcox and Johnny Aitken who won in another of the dominant Peugeots. Oval courses now dominated the AAA Championship with these two events being the only road-course races this year. It proved to be the final time these two formative American races were held in this format, as the Great War dragged the country into the global chaos in 1917.
The Wheeler-Schebler Trophy Race was an automobile race held at the Indianapolis Motor Speedway in each of the two years prior to the first Indianapolis 500. The trophy was sponsored by the Wheeler-Schebler Carburetor Company. Frank Wheeler, one of the four co-founders of the Speedway, was also the president and co-founder of Wheeler-Schebler. The 1909 race was originally scheduled for 300 miles, but was ended at 235 miles due to deteriorating track conditions.
The Harvest Auto Racing Classic was a series of three automobile races held at the Indianapolis Motor Speedway on Saturday September 9, 1916. The meet, held four months after the 1916 Indianapolis 500, featured a 20-mile race, a 50-mile race, and a 100-mile race. The main event, a 100-mile Championship Car race, paid points towards the 1916 AAA National Championship. Johnny Aitken won all three races, two of which had a margin of victory of less than a car length.
The 1919 Grand Prix season was the first season following the armistice that ended World War I in November 1918. European economies were struggling, and many automotive firms had to recover and retool from military production. So, there was very little racing activity as it took time for the companies and populations to recover. As the world rebuilt there were only two major races held in the year – the Indianapolis 500 and the Targa Florio.
