Bill Browder

Bill Browder is an American-born British financier and the co-founder and chief executive of Hermitage Capital Management, which was once the largest foreign portfolio investor in Russia. Russia barred him from entering the country in 2005 after he challenged large Russian companies as a shareholder activist. After his tax adviser Sergei Magnitsky died in Russian custody in 2009, Browder lobbied for the U.S. Magnitsky Act and similar sanctions laws elsewhere.
