Where it comes from
James Watt was born in Greenock, Scotland, on 19 January 1736, and this Story marks his birthday. He trained as a maker of mathematical instruments and opened a workshop at the University of Glasgow.
How it's celebrated
There is no formal observance, but his birthday is a good moment to look at the label on a kettle or a light bulb, where his name is printed as the unit of power. It is also a fine day to explain to a child how steam can push a piston, and how a better idea can save fuel.
Did you know
Watt did not invent the steam engine; he made it far more efficient, and the patent he took out in 1769 was for 'lessening the consumption of steam and fuel'.
