  2. JAMES WATT: Improver -- not inventor -- of the steam engine Born: 19 January 1736 Died: 19 August 1819 Birthplace: Greenock, Scotland

  3. James watt • Crude steam engines were used before Watt's time, but they burned large amounts of coal and produced little power. Their reciprocating motion restricted their use to operating pumps. James watt working

  4. Watt made steam engines more efficient by inventing the separate condenser. This device changed steam back into water by cooling.

  5. Watt's later improvements made possible the wide application of steam engines, contributing much to the growth of modern industry.

  6. WATTS LIFE • Watt was born on Jan. 19, 1736, in Greenock, Scotland. He was the son of a shopkeeper and carpenter. When Watt was 18, he went to Glasgow and then to London to learn the trade of a mathematical instrument maker. In 1757, Watt became instrument maker at the University of Glasgow.

  7. In 1763, Watt received a model of a Newcomenatmospheric steam engine to repair. Although he made it work, Watt was not satisfied with the way it operated and set about to improve it. He obtained advice from students and professors at the university and discovered the principle of the separate condenser. Watt patented his discovery in 1769.

  8. Inventor: James Watt Criteria; First practical,Entrepreneur Birth: January 19, 1736, in Greenock, Scotland Death: August 19, 1819 in Heathfield, England Nationality: Scottish Invention: steam engine improvements in 1769 Function: noun / steam engine Definition: An engine that converts the heat energy of pressurized steam into mechanical energy, especially one in which steam drives a piston in a closed cylinder. AT A GLANCE:

  9. James Watt's improvements in 1769 and 1784 to the steam engine converted a machine of limited use, to one of efficiency and many applications. It was the foremost energy source in the emerging Industrial Revolution, and greatly multiplied its productive capacity. Watt was a creative genius who radically transformed the world from an agricultural society into an industrial one. Through Watt’s invention of the first practical steam engine, our modern world eventually moved from a 90% rural basis to a 90% urban basis.
