11332 Jameswatt          
In 1765, Scottish inventor James Watt (1736-1819) suggested using a separate condenser in the steam engine, lessening the consumption of steam and fuel in fire engines. With the invention of the double-acting machine, in which the piston pushed as well as pulled, "Watt's engine" was nearly complete.
