While the Spaniard first patented a steam-operated machine for use in mining, an Englishman is usually credited with inventing the first steam engine. In 1698, Thomas Savery, an engineer and inventor, patented a machine that could effectively draw water from flooded mines using steam pressure.
It is a well known fallacy that the lead inventor of the steam engine, James Watt, was inspired by watching the power of steam lifting off a kettle lid. In all truth, Watt was truly inspired when working on a Newcomen engine at the University of Glasgow, where he attempted to repair the engine in May, 1765. It's necessary to look at the engine variations leading up to this point, to properly understand the development of the steam engine. Thomas Savery, an English inventor/engineer, developed a water pimp which utilized steam from a boiler to create its power.
