No. 7 - Nicolas Berggruen (AKA “The Homeless Billionaire”)
An eternal wanderer and worth some £985 million ($1.56 billion), art collector and founder of the Berggruen Holdings, Inc. fund of hedge funds Nicolas Berggruen prefers to live in five-star hotels despite owning homes in Los Angeles and New York. He is also the co-founder with Arianna Huffington of The World Post and a member of the international councils of the Tate Museum, London and the Museum of Modern Art, New York. Berggruen tells his Twitter followers that he is “a believer that ideas can make a better world”. Most surprisingly given this dynamo’s mammoth success, there are just 700 of them.
