Net worth: $20 billion (as of Sept. 2013)
In his early teens, Soros posed as the godson of an employee of the Hungarian Ministry of Agriculture in order to stay safe from the Nazi occupation of Hungary. Soros escaped the country to live with his relatives in London. He put himself through the London School of Economics working as a waiter and railway porter. In 1992, his famous bet against the British pound made him a billion dollars.
