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.
Maxwell automobile
For a time, Maxwell was considered one of the three top automobile firms in America, along with General Motors and Ford. (though the phrase "the Big Three" was not used at the time). Maxwell was the only profitable company of the combine named United States Motor Company, which was formed in 1910. Due to a conflict between two of its backers, the United States Motor Company collapsed in 1913 after the failure of its last supporting car manufacturer, the Brush Motor Company. Maxwell was the only survivor.
