François Caussin (1794–1866) was a French luthier who specialized in excellent copies of classic Italian works. He apprenticed under Louis Gaillard in Mirecourt before relocating to Paris to work for Didier Nicolas l'aîné, where he refined his craft. By 1815, he returned to his hometown of Rouvres-la-Chétive to set up his own workshop and finally settled in Neufchâteau around 1830. He trained his sons, Nicolas and François Hippolyte, and worked with them at different periods in his career.
Though François Caussin’s craftsmanship centered on producing exquisite replicas of Amati, Stradivari, and other fine Italian models, his antiqued varnishing became his distinct style. He produced a large number of violins, as well as a few cellos, which were also greatly admired. Many of the instruments produced in the Caussin workshop bear the label “Caussin Luthier, Neufchâteau (Vosges),” while his replicas were usually labeled with the name of the original maker.
