Watt was born to a wealthy shipwright from Greenock on the 19th January in 1736. At the start of his engineering career he began making mathematical instruments, but was soon branching out into the world of mechanics.
At the age of twenty-eight, Watt was given one of Newcomen's engines to repair, but he soon came to the conclusion that it was far from efficient and Watt's changes doubled fuel efficiency.
James Watt died on the 25th August 1819 and is buried at Handsworth near Birmingham.
