This one-of-a-kind reference work provides essential data on some 10,700 manufacturers of automobiles, beginning with the earliest vehicle that might be so termed (Frenchman Nicolas Cugnot’s steam carriage, in 1770) and covering all nations in which automobiles have been built–67 in all. Not an encyclopedia or collection of histories, this is instead a very complete registry providing essential facts about the manufacturers: complete name, location, years active, type(s) of vehicles built, and other basic data. Compiled during more than 30 years of research, this reference even lists companies that produced just one car. Any builder of passenger-carrying vehicles on at least two but no more than eight wheels, of any design, either mass produced or built as one-off specials, experimental cars, prototypes, or kit cars, is included. Builders of internal combustion, steam and electric powered vehicles are all covered; companies that built only trucks, buses, racing cars, or motorcycles are not included. From A.A.A. to Zzipper and Argentina to Yugoslavia, this is an astonishingly comprehensive resource.
