Bendor Grosvenor

In 2017, he discovered the "lost portrait" of George Villiers, 1st Duke of Buckingham at Pollok House, Glasgow, Scotland. The painting was thought to be a copy of a painting by Flemish artist Peter Paul Rubens that had been lost for nearly 400 years, but after restoration was found to be the original by Rubens.

In 2013 he discovered the lost portrait of Charles Edward Stuart by Scottish artist Allan Ramsay at Gosford House, the home of the Earl of Wemyss near Edinburgh. This portrait is now on display at the Scottish National Portrait Gallery, and has taken the place of the La Tour pastel as the definitive portrait of Charles.

During 2011–2016, he carried out specialist research for, and appeared in, the BBC1 art programme, Fake or Fortune? He now presents the BBC4 series Britain's Lost Masterpieces, with Jacky Klein and Emma Dabiri, which began in 2016, and is now filming its fifth series.

Grosvenor has made a special study of Jacobite portraiture. In 2009 he proved that the Scottish National Portrait Gallery's iconic portrait of Charles Edward Stuart by Maurice Quentin de La Tour was in fact a portrait of Charles' brother, Henry Benedict Stuart, Cardinal Duke of York.

His first major art discovery was a mis-catalogued portrait by Sir Thomas Lawrence in 2003 that was being sold at a London auction as a work by Lawrence's pupil, George Henry Harlow. From 2005 until 2014, he worked for Philip Mould Ltd, where he made a number of significant art historical discoveries, including lost works by artists such as Sir Joshua Reynolds, Thomas Gainsborough, and Sir Anthony Van Dyck, on whom he is an acknowledged specialist. In 2016 he sold a newly identified portrait by Joan Carlile, the first professional British female artist, to the Tate gallery.

Bendor Gerard Robert Grosvenor (born 27 November 1977) is a British art historian, writer, and former art dealer. He is known for discovering a number of important lost artworks by Old Master artists, including Sir Peter Paul Rubens, Claude Lorrain and Peter Brueghel the Younger. As a dealer he specialised in Old Masters, with a particular interest in Anthony van Dyck.

Grosvenor was educated at Harrow School, Pembroke College, Cambridge and the University of East Anglia where he completed his PhD entitled "The Politics of Foreign Policy: Lord Derby and the Eastern Crisis, 1875-8". Before becoming an art historian he worked in politics, first as an adviser to the Labour MP Tony Banks, Lord Stratford, and then to the Conservative MP Hugo Swire.
