The Russian oil tycoon Roman Abramovich is a billionaire, and he’s not afraid to spend his riches. He recently shelled out $90 million for a house in St. Bart’s, one of the most expensive private home sales of all time. He’s in the process of building a house in London that could be worth $200 million. Construction of his 540 ft., $300 million yacht is almost complete. Abramovich started his career as an oil trader in the early 1990s and rose to become the owner of one of Russia’s largest oil companies, OAO Sibneft. A Kremlin insider, he also became governor of a remote Russian province (where he spent some of his fortune on philanthropic projects). In 2003, he bought London’s Chelsea Football Club and he owns the Chateau de la Crose on the French Riviera (the former home of the Duke of Windsor). He has also spread his fortune around the art world, spending over $30 million for a nude portrait by Lucian Freud (the most expensive work sold by a living artist). That, however, paled in comparison to the $86 million he spent on a painting by Francis Bacon, which depicts a man being eaten by birds.
