When Wellington R Burt passed away in 1919, aged 87, he was one of the richest men in America with an estimated fortune of $100 million. But the miserly multimillionaire didn't want his family to get their hands on his money, so he put a 'spite clause' in his will that meant the money wouldn't be distributed until 21 years after the death of his last grandchild! After a 92-year wait, those conditions were finally met in May 2011 and 12 of his descendants, aged 19 to 94, split the estate.
