Jean de Hautefeuille

Died 18 Oct 1724 at age 77 (born 20 Mar 1647).French physicist who built a primitive internal-combustion engine which was intended to operate a pump. The piston was pushed back by the explosion of a small charge of gunpowder, and then returned as the combustion gases cooled, leaving a partial vacuum. He wrote on many topics, including acoustics, optics, tidal phenomena, and watch mechanisms. He also invented the micrometer microscope to measure the size of minute objects.
