Back to watch making, 3 top people in horology
Ferdinand Berthoud, the famous horologer who went to Paris to work for the King in 1745, published the first book on the construction of marine chronometers in 1760 and was sent to England in 63 to try and understand the earlier work of on marine chronometers by Harrison. The latter refused- and Berthoud continued to perfect chronometers without him! A new Brand has recently been created in his name, and his having much success.
Breguet, perhaps the most famous horologer ever- who did his initial apprenticeship with his step-father here- before going on to Paris around 1762, to continue his training, partly with Berthoud. Now owned by Hayek of Swatch fame... and in Vallée de Joux.
And Charles Edouard Guillaume, Nobel prize in 1920 for his invention that revolutionised the accuracy of chronometers and other scientific instuments- with his invention of new metals, like Invar- which practicall did not contract and expand with changes in atmospheric pressure and temperatures. Prior to this, on the Equator- each variation of 1 second would represent being off target by 500 metres- a mere minute or so being a matter of life or death- or win or loss of naval battle.
