Étienne Lenoir

Who was Étienne Lenoir?

Jean Joseph Étienne Lenoir also known as Jean J. Lenoir was a Belgian engineer who developed the internal combustion engine in 1858. Prior designs for such engines were patented as early as 1807, but none were commercially successful. Lenoir's engine was commercialized in sufficient quantities to be considered a success, a first for the internal combustion engine.

He was born in Mussy-la-Ville. By the early 1850s he had emigrated to France, taking up residence in Paris, where he developed an interest in electroplating. His interest in the subject led him to make electrical inventions including an improved electric telegraph.
