The Courvoisier family ranked among the oldest families of clockmakers at La Chaux-de-Fonds, Switzerland, and played an extremely influential role in the early history of Swiss carriage clocks. Several generations of the family were involved in the business through various associations. Josué-Robert with his son Louis (1758-1832) founded 'Robert Josué & fils'. In 1781 the firm became 'J. Robert et fils et Cie' and was run by Captain Louis Robert and Louis Courvoisier. Robert's widow continued the firm from 1787 as 'J. Robert et fils, Courvoisier et Cie'. In 1805 the name changed to 'Robert Courvoisier et Cie'.
