The beautiful, profligate and uber-fashionable Georgiana, Duchess of Devonshire was, among other things, an inveterate gambler, a savvy political campaigner and a great friend of Marie Antoinette's. Here she is depicted by Thomas Gainsborough in a 1785 portrait that has had a very adventurous history. After it disappeared from Chatsworth House, it was discovered in the 1830s in the home of an elderly schoolmistress who had cut it down so the painting would fit above her fireplace. Some years later, it was stolen from a London gallery by the "Napoleon of Crime" and recovered by Pinkerton's detective agency. Subsequently purchased by J.P. Morgan, the painting remained in the financier's family until the 1990s when it was auctioned off by Sotheby's. The winning bidder? The 11th Duke of Devonshire. So, after 200 years, the famous portrait finally found its way home.
