Portrait of engineer James Watt (1736 - 1819). A mechanical engineer who trained as a mathematical instrument-maker, James Watt invented the condensing steam-engine in 1765. He took Matthew Boulton as his partner in 1775, and developed an improved version of this engine which revolutionised industry and immortalised Watt's name, inaccurately but effectively, as the 'inventor of the steam-engine'.
