Orphaned as a child, Abramovich dropped out of college, then made a fortune in a series of controversial oil-export deals in the early 1990's. His fortune took off in 1995 when he teamed up with Boris Berezovsky to take over oil giant Sibneft at a fraction of its market value. (When Berezovsky fled Russia in 2000 to escape fraud charges, he sold out to Abramovich.)

In 2003 to 2004 sold his stake in Russian Aluminum to Oleg Deripaska. In Fall 2005 liquidated his biggest asset, selling his 72.6% stake in Sibneft to Gazprom for $13 billion. Last year got back to business in Russia, buying a stake in the country's largest steel maker Evraz Group. Sent a letter of resignation to Vladimir Putin, asking to be relieved of the post of governor of the remote northern province of Chukotka, where he has raised living standards and earned a set of passionate supporters; Putin refused. He's reportedly building a private hospital in Moscow.
