Jacques Jérôme (also Gérante) Gudin was born in Paris in 1732 as the son of Jacques Gudin and Henriëtte Le Noir. She was the daughter of jeweller Pierre Le Noir and sister of Jean-Pierre Le Noir. He became a master watchmaker on 12 May 1762, and from then on, he was based on the Quai des Orfevres. In 1783 he moved to Rue St Honoré. Jacques Jérôme signed his watches with ‘Gudin fils’ and ‘Gudin’. He worked together with Jean Baptiste André Furet (Furet) for several years.
