The steam engine was not invented by a single person but developed over time by several inventors. The first practical steam-powered device was a pump invented by Thomas Savery in 1698 to raise water from mines. Following that, Thomas Newcomen developed the first successful piston steam engine around 1712, primarily used for pumping water out of mines. Later, James Watt greatly improved the steam engine design starting in 1765 by adding a separate condenser and other enhancements, making the engine much more efficient and practical for broader industrial use. Watt's improvements were crucial to the widespread adoption of the steam engine during the Industrial Revolution.
In summary:
- Thomas Savery built the first commercially used steam-powered pump (1698).
- Thomas Newcomen developed the first practical piston steam engine (1712).
- James Watt made key improvements to steam engine efficiency and functionality (from 1765 onward).
