Édouard Delamare-Deboutteville

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.

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.

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. This patent is widely recognized as the first ever granted for a four-wheeled automobile using liquid fuel.

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.

Death He died of typhoid fever on 17 February 1901 at Mont-Grimont near Fontaine-le-Bourg and was buried in the family chapel.

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.
