Sir Harold Acton was one of the great art collectors of the 20th Century. When he died he left his collection to New York University. “Acton left 40,000 rare books, 5,000 art works, including one attributed to Donatello, and a 57-acre estate with four villas. The biggest is Villa La Pietra, a 60-room Medici family palace, whose former guests include Prince Charles, Winston Churchill, DH Lawrence and Picasso.” Now new DNA evidence has bolstered claims of those contesting the bequest.
