Alphonse Beau de Rochas


French engineer who originated the principle of the four-stroke internal-combustion engine.

Beau achievement lay partly in his emphasizing the previously unappreciated importance of compressing the fuel–air mixture before ignition. He published his results in 1861, a year after Christian Reithmann was granted a patent in Germany and 16 years before Nicolaus Otto obtained his patent.

He laid the first submarine telegraph cable in collaboration with engineer Philippe Breton ( 1850 ) and became interested in hydrography and rail traffic.

He died 27 March 1893 in Vincennes.
