James Watt was a Scottish inventor. He was born in 1736 at Greenock and died in 1819. He invented the modern steam-engine - that is he patented the separate condenser for steam engines - though not the steam-engine, that had been invented in 130BC by Hero of Alexandria and the first practical steam engine designed by Dionysius Papin in 1690 and constructed by Thomas Savery in 1698.
