As a young man in central Indiana, Clessie Cummins was well-known for his mechanical abilities. He worked for a short time in four early automotive-related industries before settling at Nordyke and Marmon.
At the inaugural Indianapolis 500 on May 30, 1911, 23-year-old Cummins served as a member of the pit crew for the Marmon Wasp, driven by Ray Harroun, which became the first winner of the race. Cummins, a test inspector for Marmon at the time, made some suggestions to help improve speed. That experience led Cummins to enter cars powered by his diesel engines in the famed race years later.
In 1919, with backing from banker William G. Irwin, Cummins founded Cummins Engine Co. in Columbus. They built a company that took advantage of the groundbreaking technology developed by German engineer Rudolf Diesel in the late 1800s. Cummins licensed a diesel patent from Dutch company Hvid expecting to sell diesels as stationary engines for farm use or as marine engines.
The notion to plant a diesel engine in an automobile or a truck didnโt hit him until December 1929 when, faced with liquidation of the company after his main financier decided diesels werenโt worth the trouble, he and chief engineer H.L. Knudsen placed a Model U four-cylinder diesel into a 1925 Packard seven-passenger limousine as a last-ditch attempt to โshow โem what a diesel can do.โ
Today, Cummins Inc. is a Fortune 500 company and a corporation of complementary business segments that design, manufacture, distribute and service a broad portfolio of power solutions. Products include diesel, natural gas, electric and hybrid powertrains and powertrain-related components, including filtration, aftertreatment, turbochargers, fuel systems, controls systems, air handling systems, automated transmissions, electric power generation systems, batteries, electrified power systems, hydrogen generation and fuel cell products. The company has around 640 wholly owned joint venture and independent distributor locations and nearly 13,000 Cummins certified dealer locations in about 190 countries and territories. That includes a location in Seymour.
