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.
American Motors Incorporated
American Motors Incorporated was established around 1946. It was very short-lived because it does not seem to have been in operation after 1949. It had executive offices on Park Avenue in New York City, as well as a factory and service facility upstate in Troy, New York.
