The first true genre painter in the United States was the German immigrant John Lewis Krimmel, who learning from Wilkie and Hogarth, produced gently humorous scenes of life in Philadelphia from 1812 to 1821. Other notable 19th-century genre painters from the United States include George Caleb Bingham, William Sidney Mount, and Eastman Johnson. Harry Roseland[5] focused on scenes of poor African Americans in the post-American Civil War South,[6] and John Rogers (1829–1904) was a sculptor whose small genre works, mass-produced in cast plaster, were immensely popular in America.
