Ferdinand Berthoud
Ferdinand Berthoud (born March 18, 1727 in Plancemont near Neuchâtel , † June 20, 1807 in Groslay near Montmorency ) was an 18th century Neuchâtel clockmaker who published numerous writings on watchmaking. His main merit was the development of a particularly robust marine chronometer .
Life
In 1745 he went to Paris, where he mainly worked with Julien Le Roy . He developed and built clocks, pocket watches and chronometers , whose time accuracy and precision he perfected. His improvements in the oscillation results of the spiral balance and the chronometer course should be emphasized here. Among other things, Berthoud was therefore also the purveyor to King Louis XV. and his grandson and successor Louis XVI. ordered. In 1795 he was elected a member of the Académie des Sciences .
In 1807, at the age of 80, Ferdinand Berthoud died in Groslay near Montmorency (Val-d'Oise) near Paris.
