• James Watt was born on January 19, 1736,
• By the age of 29, Watt created a separated condenser for steam engines. He determined the properties of steam, especially the relation of its density to its pressure and temperature. Having this in mind, he designed a separate condensing chamber for the steam engine, which seized great losses of steam in the cylinder and improved the vacuum conditions. In 1767, he built an attachment that made telescopes suitable for the measurement of distances. In 1768, he associated with John Roebuck of the Carron, a British inventor who had financed Watt's researches, and received a patent the next year for his method of lessening the consumption of fuel and steam in an engine and for other enhancements on Newcomen's device.
