My interest was pricked by a statement that the beadles of Burlington Arcade wear the uniform of Lord George Cavendish’s regiment, the tenth Hussars, to find out more about Lord George Cavendish, the early nineteenth-century owner of Burlington House.   There is not much information about him online other than the fact that he was a grandson of the third Earl of Burlington (the architect Earl), son of the fourth Duke of Devonshire, and an MP for Knareborough, Derby and Derbyshire from 1775 to 1831 (61 years).   The admirable volumes of the History of Parliament tell me more.   He was educated in Hackney and Trinity College, Cambridge, an unusual combination for the son of a Duke (where in Hackney, I wonder ?).  A member of Brooks’s and a Whig, he lived mainly at Holker in Lancashire and inherited £700,000 from his uncle Henry in 1810 which enabled him to extend Burlington House and build the Arcade.   His politics were said to be abominable and ‘his manners insolent and neglectful’.
