John Peter Van Ness Throop (April 15, 1794 - July 3, 1860), often as 'J.V.N. Throop,' not to be confused with contemporary politician John Peter Van Ness (1769 - 1846), was an engraver active in Washington, D.C. in the mid-19th century. Born in Chatham, New York, he was the son and grandson of Revolutionary War officers. It is unknown if he was related to fellow engraver Orramel Hinckley Throop, but it seems likely that they were are least distant relatives. J.V.N. Throop developed a niche as an engraver of illustrations and maps, especially nautical charts, in government documents and congressional reports.
