found: Performing Arts Encyclopedia, March 24, 2015(Hippolyte-Guillaume-Sulpice Chevalier, known by his pseudonym of Paul Gavarni, was a draughtsman, watercolorist and lithographer, who was born in Paris in 1804 and who died in the same city in 1866. He was a caricaturist whose early works were light-hearted and centered on anecdotal scenes from the daily life of fashionable Paris, particularly the world of women. Gavarni's prints had already been published in England as early as 1829. After he spent time there in 1847 and 1851, his satirical prints were no longer so light-hearted.) - http://lcweb2.loc.gov/diglib/ihas/loc.natlib.ihas.200182942/default.html
