Onésime Dumas (1824-1889). A chronometer-maker and nephew of Henri Motel, he was an apprentice first of Perrelet and then of Charles-Auguste Berthoud. After having worked for a short period with Motel, he succeeded Gannery at St. Nicolas d'Aliermont. He exhibited precision horology at Rouen in 1856 and chronometers at Paris in 1857. He was the first maker in France to produce chronometers of English caliber.
