She recorded her thoughts on tape
beeboys/Shutterstock Much of what we know about Princess Diana’s personal life is thanks to audiotapes she recorded herself. Once she recognized her marriage to Prince Charles was falling apart, she documented her side of the story on a tape recorder and gave the tapes to her close friend, Dr. James Colthurst. He, in turn, gave them to journalist Andrew Morton so her words could get out to the public. From those tapes, Morton published the biography DIANA: Her True Story—In Her Own Words in 1992. No one knew Diana had a hand in the book’s production until after her death. Here are some more surprising facts you probably didn’t know about Princess Diana.
