Édouard Napoléon François Delamare-Deboutteville (8 February 1856 – 17 February 1901) was a French inventor, engineer, and industrialist. He is known for designing and operating one of the earliest automobiles powered by a petrol-fuelled four-stroke internal combustion engine, predating the Benz Patent-Motorwagen by nearly two years.[1][2]
Early life
Delamare-Deboutteville was born in Rouen, France, into a wealthy textile industrialist family. He studied at the École Supérieure de Commerce de Rouen and later managed the family spinning mill at Mont-Grimont in Fontaine-le-Bourg.[3]
Automotive innovation
In 1883, he and mechanic Léon Malandin developed an early petrol-fuelled internal combustion engine, first mounted on a tricycle then evolved into a four-wheeled vehicle.[3] On 12 February 1884, they successfully ran a car between Fontaine-le-Bourg and Cailly.[2]
On that day, Delamare-Deboutteville filed French patent no. 160267 (associated with Malandin), which described their four-cylinder petrol vehicle with electrical ignition, chain transmission, shaft and differential.[4] This patent is widely recognized as the first ever granted for a four-wheeled automobile using liquid fuel.[2]
The vehicle specifications as described by historical sources include:
- Twin-cylinder horizontal engine (~8 hp at 250 rpm, ≈ 8129 cm³ displacement)[3][2]
- Petrol mixed with ~3% oil[3][2]
- Carburetor, chain drive, and differential[5][dead link][2]
Though fragile and never commercialized, the prototype is considered a technical milestone in automotive history.
Other work
He continued developing gas engines under the brand Simplex. He received a gold medal at the 1889 Exposition Universelle in Paris for a 100 hp gas engine.[3] The Belgian firm John Cockerill acquired manufacturing rights in July 1889 and later produced engines up to 700 hp by 1899.[6][dead link]
Delamare-Deboutteville also published works on oyster farming, Sanskrit grammar, and maintained an ornithological collection. He held over 70 patents and was made Officer of the Legion of Honour in 1896.[7][3]
Death
He died of typhoid fever on 17 February 1901 at Mont-Grimont near Fontaine-le-Bourg and was buried in the family chapel.[3]
Legacy
While Karl Benz is often credited as the "inventor of the automobile," some historians acknowledge Delamare-Deboutteville as a pioneering precursor in the development of motor vehicles. His contribution is often overshadowed by commercial successes of others.[1][2]
