Len Blavatnik was born in Ukraine in 1957, the son of two university professors. After attending Moscow University in the 1970s he emigrated from the Soviet Union to the US with his family. He graduated with a master's degree in computer science from Columbia University in 1981 and an MBA from Harvard Business School in 1989. He holds US and UK citizenship.
After school, Blavatnik worked at Mount Sinai School of Medicine in New York, where he developed pattern-recognition software that helped the school catch cheating students. He later worked at Andersen Consulting and Macy's, where he became director of information services. He began investing in New York real estate and soon recognized the opportunities emerging in Russia.
He incorporated Access Industries, a holding company, in 1986. Four years later, he partnered with his former classmate Viktor Vekselberg to make investments in aluminum businesses that were being privatized by Russian President Boris Yeltsin. The two began buying smelting factories, and eventually combined those assets into United Co. Rusal, now the world's second-largest aluminum producer. Access divested its interest in UC Rusal in a private transaction in 2022.
With Vekselberg and three billionaire partners from Mikhail Fridman's Alfa Group, Blavatnik acquired a 40 percent stake in TNK in 1997, taking control of the former state-owned oil company that had interests in several West Siberian oil fields.
BP later paid almost $7 billion to become a 50 percent owner of TNK. Fridman and his partners consolidated the other half under the holding company Alfa-Access-Renova (AAR). Their venture created TNK-BP, Russia's largest foreign oil investment. The partnership was rife with drama, including executive departures and lawsuits. But it was lucrative, paying out $38 billion in dividends through 2012. Russia's state-owned oil company, Rosneft, bought AAR's half of the venture for $27.7 billion in March 2013.
In the past decade, Blavatnik has accelerated his acquisitions, including his purchase of the now-merged chemical companies Basell in 2005 and Lyondell in 2007. Operating under heavy debt in a weak economy, LyondellBasell filed for bankruptcy in 2009. It emerged a year later, with financing from Access, among others. Its market cap surpassed $30 billion in 2020.
Blavatnik turned his sights to the music industry in 2011, buying Warner Music Group for $3.3 billion. He listed it on the Nasdaq Exchange seven years later, raising $1.9 billion. Through Access's entertainment division, he's produced numerous Hollywood films and Broadway productions. He has a multi-billion dollar stake in London-based DAZN, now the world's largest sports streaming platform.
His philanthropy, The Blavatnik Family Foundation, donates to scientific, cultural and educational institutions and fellow charitable organizations. He endowed the Blavatnik School of Government at Oxford University with a 75 million-pound gift in 2010.
