Chrysler, an American based automobile manufacter, was founded by Walter Percy Chrysler in 1924, and immediately began producing its first model. W.P. Chrysler preceded the founding of General Engines by Willys-Overland and Maxwell. In 1928, the De Soto, Dodge and Plymouth trademarks were added to the offerings of the Chrysler corporation. Since 1929, Chrysler has been the third largest producer of cars in the USA. In the 1970s, Simca, a French producer and Rootes, an English firm, were produced under the Chrysler brand (neither firm exists today). Since 1988, Chrysler has merged with Daimler Benz, a German auto producer, to become known internationally as Daimler-Chrysler.
