American automobile industry in the 1950s
In 1954, the smaller American Motors Corporation (AMC) was formed when Hudson merged with Nash-Kelvinator Corporation in a deal worth almost USD $200 million ($1.735 billion in 2013 dollars) the largest corporate merger in U.S. history at that time. Other mergers with smaller independent manufacturers followed. Although AMC was moderately successful it was never sufficiently large to challenge any of the Big Three, and was eventually bought by Chrysler in 1987.
Elmore Manufacturing Company
In 1908, Elmore's three-cylinder two-stroke caught the attention of William C. Durant, founder of General Motors. He purchased the company the following year, with Elmore becoming one of General Motors' divisions. After Durant was forced out of General Motors in 1910, the Elmore marque was soon cut, along with several other underperforming brands, to help General Motors achieve financial stability.
