john chamberlaine (1745 - 1812)
Hans Holbein the Younger was a German-Swiss 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.
John Chamberlaine was a British antiquarian and curator of the Royal Collection.
Chamberlaine worked as keeper of George III's drawings, coins and medals from 1791 until his death in 1812. In collaboration with George III's chief librarian, Frederick Augusta Barnard, he published many copies of drawings from the Royal Collection, and the engraver for this work was Francesco Bartolozzi (1728-1815).
