Roy D. Chapin applauds President
Herbert Hoover at the Nine-Point Prosperity Conference (August 26, 1932) Chapin was general sales manager of Olds Motor Works from 1904 to 1906. He then started
E. R. Thomas-Detroit Company with Edward R. Thomas, and was its treasurer and general manager from 1906 to 1908. Chapin headed the consortium of businessmen and engineers that founded the
Hudson Motor Car Company in 1908. The company was named for
Detroit merchant
Joseph L. Hudson, who provided the majority of capital for the operation's start-up. Chapin was also behind the 1918 formation of the
Essex Motors Company, a subsidiary of Hudson. Essex is notable for developing the first affordable mass-produced enclosed automobile in 1922. Because of the success of the inexpensive enclosed Essex Coach line, the American automobile industry shifted away from open
touring cars in order to meet consumer demand for all-weather passenger vehicles. By 1929 Hudson-Essex reached 3rd in industry sales behind Chevrolet and Ford. In 1927 he replaced Clifton as the head of the National Automobile Chamber of Commerce. In addition to his corporate interests, Chapin spearheaded the drive to build the
Lincoln Highway, along with
Henry B. Joy of
Packard Motors. While Chapin viewed a system of professionally designed and built roadways as the greatest way to grow the automobile industry, he also saw the modern roadways movement as a way to secure long-range strength for the United States as a nation. ==Political activities==
