Henry undertook an extensive Grand Tour between June 1801 and August 1803, his travels taking him to Copenhagen, Saint Petersburg, Moscow, Berlin, Prague, Vienna, Switzerland and throughout Italy.
[1] In March 1803 he joined Sir William Drummond and George Hamilton-Gordon, 4th Earl of Aberdeen, on Captain Sir John Gore's ship HMS Medusa to bring Drummond to Constantinople.
[2] He entered Parliament as one of two representatives for Warwick in 1802, a seat he held until he succeeded his father in the earldom in 1816.
He served as a Lord-in-waiting (government whip in the House of Lords) from 1841 to 1846 in the second Tory administration of Sir Robert Peel.
His print Landscape with Old Trees by Water—one of the first lithographs made in Britain—was published in the portfolio Specimens of Polyautography in 1803.
