James Watt was a great Scottish engineer of the 18th century. He did not actually invent the steam engine. Instead, he

Improved it. A man named Thomas Savery invented the first primitive steam engine in 1698. A man named Newcomen started making steam engines to pump water from mines in 1712. However , Watt is famous for inventing an improved version in 1769.

James Watt was born in Greenock on January 19, 1736. Hs father, also called James, was shipbuilder. As a boy Watt attend the local grammar school where he studied classics and mathematics. The young Watt also liked making models.

Eventually, watt decided to become a maker of mathematical instruments, such as quadrants and compasses. In 1755 he went to London, but only lived there for two years before moving to Glasgow.

In 1964 Watt improved on a model of a Newcomen steam engine. In the Newcomen`s the steam was pushed into a cylinder, then condensed back into water. A year later Watt realised it would be more efficient to condense the steam in another chamber separate from the cylinder. However , it was not until 1769 that Watt patented his knew idea, the separate condenser.

In 1766 Watt landed a job as a land surveyor marking out land for canals and eight years later he moved to Birmingham. In 1775 he went into partnership with MatthewBoulton and began making steam engines which were used for pumping water out of mines.

By 1780 the Industrial Revolution was beginning to transform life in Britain and Watt adapted his steam engines to provide a rotary motion so they could be used to power machines in new factories. In 1781 he used the sun and planet gear to do this and four years later, steam engines were used to power machines in cotton mills for the first time.

Meanwhile, in 1782 Watt invented another major improvement, the double-acting steam engine. In 1788 he invented the fly ball governor to regulate the speed of steam engines and a pressure gauge in 1790.

In 1785 Watt was elected a fellow of the royal society and he retired from business in 1800.
