James Watt
From Wikipedia, a free encyclopedia written in simple English for easy reading.
James Watt (January 19, 1736 - August 19, 1819) was a Scottish mathematician and engineer. He did not invent the first steam engine. There were other patented steam engines (such as the Savery and Newcomen steam engines) in use by the time Watt started his work on them. His major contribution is in developing the modern form of the steam engine. The Watt steam engine is credited for driving the Industrial Revolution of the 18th and 19th centuries.
Today, we honor him by naming a unit of power, the watt, after him.
