by The Inventor of the Practical Four-Stroke Engine That Powered a New Age
This nomination for Nikolaus August Otto, the German engineer who in 1876 built the first practical and efficient four-stroke internal combustion engine, the “Otto Cycle” engine. While others had built earlier prototypes, Otto’s reliable, stationary gas engine was the breakthrough that made the technology commercially viable for industry and, later, adaptation for transportation. It provided a new, compact, and powerful source of mobile energy. This invention was the essential precursor to the automobile, the airplane, and countless other machines. Otto proved that mastering the controlled explosion of fuel inside a cylinder could unlock a new era of personal and industrial mobility, setting in motion the petroleum age and revolutionizing logistics, urban design, and global trade in ways that defined the 20th century.
