1). James Watt, a famous inventor and mechanical engineer, was born on January 19, 1736, in Scotland. He worked as a mathematical-instrument maker from the age of 19 and soon became interested in improving the steam engine, which was used at that time to pump out water from mines.
2). Watt is known for his improvements of the steam engine. He determined the properties of steam, especially the relation of its density to its temperature and pressure, and designed a separate condensing chamber for the steam engine that prevented large losses of steam in the cylinder. For this device and other improvements on steam engine Watt received his first patent in 1769.
3). Watt continued his research and patented rotary engine for driving various types of machinery; the double-action engine, in which steam is admitted alternately into both ends of the cylinder; and the steam indicator, which records the steam pressure in the engine. He retired from the firm manufacturing steam engines in 1800 and devoted himself entirely to research work.
4). In 1788 Watt invented the centrifugal or flyball governor, which automatically regulated the speed of an engine. It uses the feedback principle of a servomechanism, linking output to input, which is the basic concept of automation. The watt, the union of power, was named in his honour.
