The most prominent member of the family to die recently was David Rockefeller, who passed away at age 101 in 2017. At the time of his death, he was the world's oldest billionaire, as well as the last living grandchild of John D. Rockefeller.
David had a net worth of around $3.3 billion (£2.6bn) and, like his grandfather, was involved in charitable works. His will stated that once all assets had been liquidated, over $700 million (£520m) should be donated to a range of non-profit organisations. Beneficiaries included Harvard, the Museum of Modern Art, and the Rockefeller University.
His son, David Rockefeller Jr, has held various positions in the family business and is a trustee of the Rockefeller Brothers Fund and the David Rockefeller Fund. He's worth considerably less than his late father as the family's wealth becomes ever more diluted.
