Hans Holbein the Younger (1497 - 1543) was a German painter and printmaker who worked in a Northern Renaissance style, and is considered one of the greatest portraitists of the 16th century. He also produced religious art, satire, and Reformation propaganda, and he made a significant contribution to the history of book design. He is called "the Younger" to distinguish him from his father Hans Holbein the Elder, an accomplished painter of the Late Gothic school. By the time Holbein began his apprenticeship under Hans Herbster in Basel, he was already steeped in the late Gothic style, with its unsparing realism and emphasis on line, which influenced him throughout his life. In Basel, he was favoured by humanist patrons, whose ideas helped form his vision as a mature artist.
