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.
Scientists began tinkering seriously with steam in the early 1600s and, like most inventions of the day, it was a team effort that ultimately led to the first working steam engine. In 1698, British inventor Thomas Savery patented a steam-powered pump, which he described as an engine to raise water by fire..Savery's very basic engine relied on steam to create a vacuum and pull water upwards through a pipe â a theory that had been around for several centuries but never successfully applied.cientists began tinkering seriously with steam in the early 1600s and, like most inventions of the day, it was a team effort that ultimately led to the first working steam engine.
