J. M. French (James Moore French), also known in Spain as Santiago James Moore French, was born in Ireland, but set up business in London. He made clocks, watches and chronometers and was active in the trade between 1808 and 1842. He probably studied under Robert Pennington, given the similarity between many of the technical features of the two clockmakers. French was admitted to the Worshipful Company of Clockmakers in 1810 and went on to specialise in the manufacture of marine chronometers. He had a business at 15 Sweeting's Alley, Royal Exchange, London (1808-1838) and later at 18 Cornhill, London (1839-1842). Following his death, the brand expanded throughout Europe and especially Spain. His widow married José Rodríguez de Losada, a Spanish clockmaker, originally from León, who had worked in French's workshop and continued marketing the brand.
