James Watt

James Watt (1736-1819) was an engineer who invented the steam engine with external condenser.

Biography
In 1765, Watt was working on improving Thomas Newcomen's steam engine, which was still only in small-scale use. The cold water used in the engine wasted a great deal of heat, so Watt added a separate component to condense steam outside the cylinder and avoid continuous chilling. Watt teamed up with Matthew Boulton in the 1770s with Birmingham industrialist to put his improvements into practice. His invention transformed the steam engine from a pump of limited use to the source of power that drove the Industrial Revolution.
