The Duchess is a 1998 biography of the 18th-century English aristocrat Georgiana Spencer Cavendish, Duchess of Devonshire [1757-1806], based on the book by English biographer Amanda Foreman. The Duchess Georgiana was played by Keira Knightley, with Ralph Fiennes as the Duke. Also starring Charlotte Rampling.
Georgiana was a source of inspiration in political campaigning, fashion and collecting. She was an early enthusiast of mineral collecting (her collection remains at Chatsworth today). And was a friend of Marie Antoinette (1755-93), and as a result promoted French tastes in art, dress and furniture in England. Her son William Cavendish Spencer, or 'Hart' as he was known became the 6th Duke of Devonshire, and added vastly to the collection at Chatsworth. His innovative thinking and partnership with Joseph Paxton developed many of Chatsworth's features which we still enjoy today.
