	'''Nikolaus August Otto''' (14 June 1832, Holzhausen an der Haide, Nassau - 26 January 1891, Cologne) was the German inventor of the first [[internal-combustion engine]] to efficiently burn fuel directly in a [[piston]] chamber. Although other internal combustion engines had been invented (e.g. by [[~~Ãtienne~~ Lenoir]]) these were not based on four separate strokes. The concept of four strokes is likely to have been around at the time of Otto's invention but he was the first to make it practical.
