Automobiles Delaunay-Belleville was a French luxury automobile manufacturer from St. Denis sur Seine, France. At the beginning of the 20th century they were among the most prestigious cars produced in the world, and perhaps the most desirable French marque.
S.A. des Automobiles Delaunay-Belleville was formed in 1903 by Louis Delaunay and Marius Barbarou. Barbarou’s family owned the boiler making company St. Denis in Belleville, with boiler design influences inspired by the company. Marius had experience working for Clement, Lorraine-Dietrich and Benz and was responsible for design and styling. The first car was exhibited at the 1904 Paris Salon and in 1906 SA des Automobiles Delaunay Belleville was formed to look after car manufacture.
