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.
General Motors
General Motors Company was formed on September 16, 1908, in Flint, Michigan, as a holding company controlled by William C. Durant, owner of Buick. At the beginning of the 20th century, there were fewer than 8,000 automobiles in the U.S., and Durant had become a leading manufacturer of horse-drawn vehicles in Flint, in the 1880s and 1890s, before making his foray into the automotive industry in 1904 by purchasing the fledgling Buick Motor Company. GM's co-founder was Charles Stewart Mott, whose carriage company was merged into Buick prior to GM's creation. Over the years, Mott became the largest single stockholder in GM, and spent his life with his Mott Foundation, which has benefited the city of Flint, his adopted home. GM acquired Oldsmobile later that year. In 1909, Durant brought in Cadillac, Elmore, Oakland, and several others. Also in 1909, GM acquired the Reliance Motor Truck Company of Owosso, Michigan, and the Rapid Motor Vehicle Company of Pontiac, Michigan, the predecessors of GMC Truck. Durant, along with R. S. McLaughlin, lost control of GM in 1910 to a bankers' trust, because of the large amount of debt taken on in its acquisitions, coupled with a collapse in new vehicle sales.
