Charles Williams Nash was an American automobile entrepreneur who served as an executive in the automotive industry. He played a major role in building up General Motors. In 1916, he bought Thomas B. Jeffery Company, makers of the popular Rambler automobile, renamed it Nash Motors, and played an independent role in an automobile industry increasingly dominated by the Big Three: General Motors, Ford, and Chrysler. His profits came from focusing on one well-designed car in the upper medium price range. He bought several distressed companies in Wisconsin, merging them and installing advanced managerial accounting procedures while cutting costs and focusing on long-term growth. He retired as president in 1932 but remained chairman of the board. His major acquisition was the merger in 1937 with the Kelvinator Company, which made refrigerators. During World War II, Nash-Kelvinator greatly expanded to manufacture aircraft engines and parts.
