Ariston was an American automobile brand established in 1906 by L.D. Sheppard in Chicago, Illinois. The company produced vehicles for a brief period, offering two distinct models during its short existence. The first was the 30/35 horsepower Model S, and the second was the more powerful 40/50 horsepower Model G. Despite the introduction of these models, Ariston did not survive beyond the year of its founding, marking it as a short-lived venture in the early automotive industry.
