Ferdinand Berthoud, a Swiss watch and clockmaker, was born in 1727 in Val-de-Travers in the Canton of Neuchâtel. In 1745, at the age of 18, he moved to Paris and began to practice his watchmaking skills there. He was a scientist, a master horologist, and a movement maker. He authored many works of his own and contributed numerous articles in the Encyclopédie. He worked tirelessly on the development of marine chronometers as the stakes were genuinely global: ocean-going voyages stayed on course by calculating the difference between local solar time and a given meridian. The east-west position of ships, their route, and their arrival point depended on these ‘on board’ and ‘departure’ times being accurate. Both France and England were offering substantial awards to the first person to find the solution.
