 Ottin was responsible for the assembly in 1834 of the vast "surtout de table" of hunting vignettes, commissioned for the Tuileries Garden by Louis-Philippe's heir, Ferdinand-Philippe, duc d'Orléans, and entrusted to the supervision of Claude-Aimé Chenavard, who gave much of the sculptural work to Antoine-Louis Barye, the celebrated "animalier".In 1836 he shared with Jean-Marie Bonnassieux the Grand Prix de Rome for a sculpture of "Socrates drinking the draft".One vestige of his Roman sojourn of 1836-40 is a "View of Rome", 1837, in graphite and watercolor, at the Fine Arts Museums of San Francisco.
