In 1913, German-American brothers Fred and Augie Duesenberg founded Duesenberg Motors Company, Inc. on University Avenue in St. Paul, Minnesota, to build engines and race cars. The brothers were self-taught engineers and built many experimental cars. Duesenberg cars were considered some of the best cars of the time, and were built entirely by hand. In 1914, Eddie Rickenbacker drove a "Duesy" to finish in 10th place at the Indianapolis 500, and Duesenberg won the race in 1922, 1924, 1925, and 1927. The fledgling company sidestepped into aviation engine manufacturing when Colonel R.C. Bolling and his commission acquired a license to produce the Bugatti U-16 for the U.S. Army Air Service. The end of World War I stopped this project before it could ever mature.
