Mark Getty and family

101= £400m Inheritance and media

Oil was the foundation of the Getty fortune, but now the family has a new means of making money: the image rights to photographs. In 1994 Getty, 43, founded Getty Images, which has expanded by buying picture libraries around the world. Since the company was floated on Nasdaq in 1997, its share price has soared, valuing it at £1.6 billion. The British branch of the family's stake is worth £250m. The estate of Getty's father, Sir John Paul Getty, who died last year, adds £150m to the family's wealth.
