Michael Bloomberg

 
Michael Bloomberg: Michael Bloomberg managed to get much richer during 2008. In March 2008, Bloomberg’s net worth was listed as $11.5 billion by Forbes in their Celebrity Billionaires list. However, by September 2008, this man’s net worth was listed as $20 billion and rising in Forbes’ 400 Richest Americans list. At the same time, Bloomberg campaigned for an amendment to New York City’s term limits law, allowing him to run for a third term in 2009. But, his wealth also provides room for his philanthropic efforts, including the donation of over $300 million to Johns Hopkins University, where he served as the chairman of the board from 1996 to 2002.
