Its founder, Henry J. Kaiser was a United States industrialist who started making an automobile with the brand name Kaiser after World War II. He also built a small car called the Henry J . The Henry J was also sold through Sears-Roebuck catalogs under the brand name Allstate In 1953, Kaiser purchased the assets of the Willy-Overland Corporation, makers of Willys brand compact cars and Jeep brand name products.

Production of Kaiser and Willys automobiles ceased during the 1955 model year, but continued the production of Willys Jeeps in Toledo, Ohio. Kaiser continued automobile production in Argentina and Brazil using the dies formerly employed in the U.S. well into the 1960s.
