He didn't invent it, he simply improved upon the Newcomen steam engine to make it a more viable machine and consequently helped begin the industrial revolution in Britain.
Producing mechanical motion by means of 8low pressure) steam goes back over 2000 years, but early devices were not practical. Centuries after, the Spanish inventor Jerónimo de Ayans y Beaumont patented in 1606 the first steam engine. In 1698 Thomas Savery patented a steam pump that used steam in direct contact with the water being pumped. The first commercial true steam engine using a piston, and was used in 1712 for pumping in a mine and was made by Thomas Newcomen.

The saying goes 'need is the mother of invention.' It must have been thought that the use of a machine to produce power could take the load off of manual and animal labor. Indeed the steam engine saved a lot of time and improved efficiency. The establishment of steam engine power propelled civilizations use of non-renewable energy accelerating the rate of technological progress. As rail networks spread across the world the movement of people and goods became possible on a massive and rapid scale.
