De Dion-Bouton Biplace Type L from 1901, one cylinder, 699 cc, 6 HP, 45 km/h

De Dion-Bouton was a French automobile manufacturer and railcar manufacturer operating from 1883 to 1953. The company was founded by the Marquis Jules-Albert de Dion, Georges Bouton, and Bouton’s brother-in-law Charles Trépardoux.

The company was formed in 1883 after de Dion saw a toy locomotive in a store window in 1881 and asked the toymakers to build another. Engineers Bouton and Trépardoux had been eking out a living with scientific toys at a shop in the Passage de Léon, near “rue de la Chapelle” in Paris.
