Best known for his caricatures published in several Parisian journals in the late 19th century, Louis Pierre Gabriel Bernard Morel-Retz left legal studies to be a student in the Parisian studio of the Swiss painter Charles Gleyre (1806-1874). He exhibited in the Paris Salons of 1857, 1864 and 1865, mostly watercolors. His etchings were published under the pseudonym “Stop” by Alfred Cadart (1828-1875), including Un Marché italien (An Italian market, 1864, Bailly-Herzberg 130), which Cadart published as part of the series issued for La Société des Aqua-fortistes (The Society of Etchers). He became a prolific caricaturist for L’Illusration, Journal amusant and Charivari, famous for his Salons Comiques, satires of art works shown in the Salons and caricatures of the artists. He published albums of prints, including Bêtes et gens (“Beasts and Men”), Ces Messieurs (These Gentlemen) and Nos Excellences (Our Excellencies). Stop also designed lithographic titles for music sheets. (TNB 7/2010) Selected bibliography:**Bailly-Herzberg, Janine.
