Chief Executive of Severstal
Billionaire Alexey Mordashov is nicknamed "the tank", according to the BBC, a moniker he may have earned from his relentless rise to power and wealth. Born in 1965, Mordashov is the son of mill workers and started his career at the Cherepovets Steel Mill in north-western Russia in 1988.
Mordashov made his fortune after the privatization of Cherepovets, in which he was a major shareholder, following the fall of the Soviet Union. Cherepovets was renamed "Severstal" and is now one of the largest steelmakers in Russia.
Mordashov was made chief financial officer of Severstal in 1992 and chief executive in 2006. He owns 82 percent of the company, according to the Financial Times. He is also the chairman of the World Steel Association and holds degrees from both the Leningrad Institute of Engineering and Economics and the Newcastle Business School of Northumbria University in the U.K.
