David Mayer de Rothschild

Of the "de Rothschild" arm of the fam, there's David, the son of Sir Evelyn de Rothschild and his wife Lynn (who were introduced by Henry Kissinger). An heir after our own hearts, David certainly knows how to use his dough for some epic fun. He's known officially as an "adventurer" and as a passionate environmentalist. In 2010, he made waves - quite literally - when he sailed from San Francisco to Sydney in a boat made of 12,500 reclaimed plastic bottles. Unsurprisingly, he's involved with various organizations and initiatives aiming to save the planet and has apparently settled in California.
