2005 - Lord Lichfield, the Royal photographer died at the age of 66 after suffering a major stroke.
(Apart from being an excellent photographer he endeared himself to me by using a whistle to keep the Royal Family in order when taking the photographs at Charles and Diana's wedding - I am sure that he and Diana will have a few interesting words to say to each other.)
