of France (to 1914), and Miesse of Belgium (to 1926). Volume production 1900 to 1913 There were a large number of new companies formed in the period from 1898 to 1905. Steam cars outnumbered other forms of propulsion among very early cars. In the U.S. in 1902, 485 of 909 new car registrations were steamers. From 1899, Mobile had ten branches and 58 dealers across the U.S. The center of U.S. steamer production was New England, where 38 of the 84 manufacturers were located. Examples include White (Cleveland), Eclipse (Easton, Massachusetts), Cotta (Lanark, Illinois), Crouch (New Brighton, Pennsylvania), Hood (Danvers, Massachusetts, lasted just one month), Kidder (New Haven, Connecticut), Century (Syracuse, New York) and Skene (Lewiston, Maine, the company built everything but the tires). By 1903, 43 of them were gone and by the end of 1910 of those companies that were started in the decade those left were White which lasted to 1911, Conrad which lasted to 1924, Turner-Miesse of England which lasted to 1913, Morriss to 1912, Doble to 1930, Rutherford to 1912, and Pearson-Cox to 1916. Assembly line mass production by Henry Ford dramatically reduced the cost of owning a conventional automobile, was also a strong factor in the steam car's demise as the Model T was both cheap and reliable. Additionally, during the 'heyday' of steam cars, the internal combustion engine made steady gains in efficiency, matching and then surpassing the efficiency of a steam engine when the weight of a boiler is factored in. Decline 1914 to 1939 With the introduction of the electric starter, the internal combustion engine became more popular than steam, but the internal combustion engine was not necessarily superior in performance, range, fuel economy and emissions. Some steam enthusiasts feel steam has not received its share of attention in the field of automobile efficiency. Apart from Brooks of Canada, all the steam car manufacturers that commenced between 1916 and 1926 were in the United States. Endurance (1924-1925) was the last steam car manufacturer to commence operations. American/Derr continued retrofitting production cars of various makes with steam engines, and Doble was the last steam car manufacturer. It ceased business in 1930. Air pollution, fuel crises, resurgence and enthusiasts From the 1940s onward, various steam cars were constructed, usually by enthusiasts. Among those mentioned were Charles Keen, Cal Williams' 1950 Ford Conversion, Forrest R Detrick's 1957 Detrick S-101 prototype, and Harry Peterson's Stanley
