Duesenberg was founded in 1913 in Des Moines, Iowa, by brothers Frederick and August Duesenberg. Their original intent was to make sports and racing cars, and as early as 1914, a Duesenberg had finished as high as tenth place in the Indy 500, at the hands of the famous Eddie Rickenbacker. With the outbreak of WWI, Duesenberg, which had still never really had a proper production model car for the public, switched to building aircraft engines. The engine it built, under license, was the Bugatti U-16. This was an impressive engine, and following the war, the brothers developed their own unique and revolutionary engine.
