John Chamberlaine

John Chamberlaine (1745 – 12 January 1812 in Paddington Green) was an antiquary and acted as keeper of George III's drawings, coins and medals from 1791 until his death in 1812.

He published prints of drawings in the Royal Collection by Holbein, Leonardo, Annibale Carracci and others, for which Francesco Bartolozzi (1728–1815) the engraver and etcher, was commissioned as a printmaker.

The work was titled Imitations of Original Drawings by Hans Holbein in the Collection of His Majesty for the Portraits of Illustrious Persons of the Court of Henry VIII.

The biographical notes were provided by Edmund Lodge, the Lancaster Herald, the vast majority of the plates being engraved by Francesco Bartolozzi, whom Dalton had imported from Florence in 1764, and some by Anthony Cardon (1772–1813).
