Diana, Princess of Wales | Royal | $25 million

Endeared to the masses, Diana, Princess of Wales, or Princess Diana to many, was Prince Harry and Prince William’s mother. As the then-wife of Prince Charles, she was set to become the queen one day. Diana was given credit for her involvement in a variety of philanthropic work when she was alive. Despite being part of the nobility class, she set her sights on helping ordinary people.

Diana was not only famous in Great Britain, but she was also a prominent international figure who was subject to frequent media scrutiny on account of her marriage with a crown prince. They were said to be incompatible in many respects, which led to frequent marital issues. This did not stop the princess, though, from doing her royal work. At the time of her passing, Diana had a net worth of $25 million, which would have been inherited by both her sons.
