Noted Watch and Chronometer Maker, Thomas Earnshaw Blue Plaque


Thomas Earnshaw (4 February 1749 - 1 March 1829) was an English watchmaker who first simplified the process of marine chronometer production, making them available to the general public.

He's also known for his improvements to the transit clock at the Royal Greenwich Observatory in London and his invention of the chronometer escapement and the bimetallic compensation balance.

Although, he was principly a watchmaker, he didn't shy away from building clocks. When asked by Nevil Maskelyne, he produced a clock for the Armagh Observatory, which is recognised by horologists today as one of the world's most important clocks.

And so to this spot - yes here was the site of the business premises of Thomas Earnshaw which is now rightly adorned with a Blue Plaque.
