FERDINAND BERTHOUD WAS ONE OF THE RARE 18TH CENTURY HOROLOGISTS ABLE TO WIELD THE PEN AND THE FILE WITH EQUAL DEXTERITY. CAPITALISING ON HIS TALENT AS AN AUTHOR, WHICH GREATLY CONTRIBUTED TO HIS REPUTATION, HE PRODUCED IN THE COURSE OF HIS CAREER A RICH BODY OF PUBLISHED WORK, DRIVEN BY THE KNOWLEDGE-SHARING IDEAL CHARACTERISING THE AGE OF ENLIGHTENMENT. IN 1753, HE GAVE THE FIRST PROOF OF HIS PENMANSHIP IN THE “LETTRE SUR L’HORLOGERIE” (LETTER ON HOROLOGY), FOLLOWED IN 1759 BY “L’ART DE CONDUIRE ET DE RÉGLER LES PENDULES ET LES MONTRES” (THE ART OF OPERATING AND ADJUSTING CLOCKS AND WATCHES) AND IN 1763 BY THE “ESSAI SUR L’HORLOGERIE” (ESSAY ON HOROLOGY), WHICH WERE TWO STAGES IN THE SAME INSTRUCTIVE PROJECT AIMED AT EDUCATING BOTH HOROLOGISTS AND ENTHUSIASTIC CONNOISSEURS.
