Romney was born to American parents living in the Mormon colonies in Mexico; events during the Mexican Revolution forced his family to flee back to the United States when he was a child. The family lived in several states and ended up in Salt Lake City, Utah, where they struggled during the Great Depression. Romney worked in a number of jobs, served as a Mormon missionary in the United Kingdom, and attended several colleges in the U.S. but did not graduate from any of them. In 1939, he moved to Detroit and joined the American Automobile Manufacturers Association, where he served as the chief spokesman for the automobile industry during World War II and headed a cooperative arrangement in which companies could share production improvements. He joined Nash-Kelvinator in 1948, and became the chief executive of its successor, American Motors Corporation, in 1954. There he turned around the struggling firm by focusing all efforts on the compact Rambler car. Romney mocked the products of the "Big Three" automakers as "gas-guzzling dinosaurs" and became one of the first high-profile, media-savvy business executives. Devoutly religious, he presided over the Detroit Stake of The Church of Jesus Christ of Latter-day Saints.
