Auguste-Louis-Marie Jenks Ottin (1811–1890) was a French academic sculptor and recipient of the decoration of the Legion of Honor.
Ottin was born and died in Paris, where he was a pupil of David d'Angers and of the École des Beaux Arts. Ottin was a friend of Théodore Chassériau, a pupil in the atélier of Ingres, who in 1833 produced a black chalk portrait of Ottin. (Presented to the National Gallery of Art, Washington, in 2006.) Ottin obtained the Grand Prix de Sculpture at the Concours of 1836 with his statue of "Socrate Buvant la Ciguë.".
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.
His portrait bust of the painter and Director of the Academy, Jean-Auguste-Dominique Ingres, executed shortly after his return to Paris in 1840, in plaster, tinted terracotta, is conserved by the École nationale supérieure des Beaux-Arts, Paris.
Ottin exhibited in 1841 a bust in marble, and afterward produced a group of "Hercules Presenting to Eurysthea the Apples of Hesperides," in marble; busts of Chaptal, Quesnault, Ingres, (1842); and Ecce Homo, in marble, (1844). His 1846 "Indian Hunter Surprised by a Boa" in bronze resulted in the awarding of a medal and was a featured piece under the center dome of the New York Crystal Palace in 1853, and was later mounted at Fountainebleau Chateau outside Paris.
