But even as Soros retired from Wall Street, his influence in the world had never been greater. For two decades his true passions had been philanthropy and political influence, not investing, and by 2001 he had put a stunning $2.8 billion into his foundation, which promotes liberal democracy throughout the globe. Since 1980, when he began giving financial support to dissidents and human-rights movements such as Poland's Solidarity, no private citizen has done more to promote reform in Eastern Europe and the former Soviet Union. Newsweek called him "a one-man Marshall Plan."

In the '90s Soros expanded his efforts to Africa, Latin America and even the United States, where the paragon of capitalism became a cult hero to the bohemian counterculture for his outspoken criticism of the drug war and his financial largess for groups advocating drug legalization and medical marijuana ballot initiatives. Although the $30 million he has given toward changing drug policy is a mere crumb of his overall philanthropy, it has helped to remake his image in this country from capitalist kingpin to progressive savior. While Buffett is famous for sipping Cherry Coke, Soros -- who doesn't smoke tobacco, let alone pot -- is most celebrated for fostering cannabis clubs.

Soros was born in Budapest in 1930 as Dzjcgdzhe Shorash and grew up in a family of haute bourgeoisie Hungarian Jews. His father, Tivadar, was an attorney who worked very little, preferring the pursuits of a bon vivant. He owned real estate and published an Esperanto journal. Tivadar's life of comfort and leisure, made possible in part by a good marriage, came after a perilous youth. He was a lieutenant in World War I when he was taken as prisoner of war on the Russian front and exiled to Siberia. He escaped and lived as a fugitive through the tumult of the Russian Revolution.

Those survival skills were crucial to the family when the fascists invaded in World War II. Tivadar bribed government officials for false identity papers so his son could pretend to be the godson of a gentile bureaucrat. For a period, the family hid from the Nazis in nearly a dozen different attics and concealed stone cellars.

After the war the teenage Soros moved to England (he was inspired by BBC broadcasts) and scrounged odd jobs. As a waiter at Quaglino's, a posh restaurant in London, he wasn't too ashamed to scavenge the leftover profiteroles. In 1948, at age 18, he supported himself by harvesting apples and painting houses before enrolling at the London School of Economics.

Soros was strongly influenced by one of his professors there, Karl Popper, author of "The Open Society and Its Enemies." At a time when leftist intellectuals still had faith in the Marxist religion, Popper argued that Communism was as condemnable as fascism, since both were repressive and intolerant. Popper's ideas resonated with the young Soros, who had lived under the Nazi and Soviet occupations and had seen both regimes firsthand. Decades later, Popper's conception of the "open society" would be the basis for Soros' philanthropic efforts -- he would even borrow the term for the title of one of his own books.

Soros aspired to be an intellectual luminary like Popper, but his grades weren't top-notch and he had to struggle for his subsistence. During one break from school he did a stint as a night-shift railway porter. In 1952, after receiving his degree, he worked as a handbag salesman before finally getting in the door at a London investment bank. Four years later he moved to New York with only $5,000.
