The Nash car company was founded by Charles W. Nash, a director of General Motors who decided to go out on his own in 1916, and the company continued to produce vehicles as part of Kelvinator (hence its early development of air conditioning) and American Motors until 1957. Mine was a 1948 coupe, with a straight 6 cylinder engine. It transported me faithfully in Chicago (near its hometown of Kenosha, Wisconsin) and in Galveston, Texas until it met an untimely end in Hurricane Ike. It was a beauty, and I enjoyed long rides in the countryside in it.
Nash made aircraft engines during WW II, including the 18 cylinder Pratt & Whitney, at the time the most powerful on earth.
