Now a brand of Maxima Technologies, Stewart Warner is perhaps the most recognized name in vehicle instruments in the history of the U.S. automotive industry. In fact, the brand dates back to 1905 when John Stewart founded Stewart & Clark Company. Stewart brand speedometers were first used on original Ford Model Ts, after which the company established itself as a market leading supplier of instruments. Seven years later, in 1912, Stewart and Edgar Bassick joined forces to create a new company to manufacture vehicle instruments and horns. Bassick, whose acquisitions included the Alemite Company, and Stewart also acquired the Warner Instrument Company and, as such, the Stewart-Warner Instrument Corporation was born.
