Louis Chevrolet
Also in 1916, American Motors Corporation (unrelated to the later American Motors created by the 1954 merger of Nash-Kelvinator Corporation and Hudson Motor Car Company) was formed in Newark, New Jersey, with Louis Chevrolet as vice president and chief engineer. By 1918 it was producing cars in a plant at Plainfield, New Jersey. In 1923 it merged with the Bessemer Motor Truck Company of Pennsylvania into Bessemer-American Motors Corporation, which lasted less than a year before merging with the Winther and Northway companies into Amalgamated Motors. The latter company apparently ceased soon after.
REO Motor Car Company
Ransom E. Olds was an entrepreneur who founded multiple companies in the automobile industry. In 1897 Olds founded the Olds Motor Vehicle Company, makers of Oldsmobile (later to become a part of General Motors). In 1905 Olds left Oldsmobile and established a new company, REO Motor Car Company, in Lansing, Michigan. Olds had 52 percent of the stock and the titles of president and general manager. To ensure a reliable supply of parts, he organized a number of subsidiary firms like the National Coil Company, the Michigan Screw Company, and the Atlas Drop Forge Company.
