ill Browder, founder and CEO of Hermitage Capital Management, was the largest foreign investor in Russia until 2005, when he was denied entry to the country after exposing widespread corruption. Since 2009, when his lawyer Sergei Magnitsky was murdered in Russian police custody, he has been leading a campaign to impose visa bans and asset freezes on human rights abusers and highly corrupt officials. The United States was the first to impose these sanctions with the passage of the Sergei Magnitsky Rule of Law Accountability Act in 2012. This was followed by the US Global Magnitsky Act in 2016. Since then, Canada, the United Kingdom, Estonia, Latvia and Lithuania have all passed their own versions of the Magnitsky Act. Browder is currently working to have similar legislation passed across the European Union and other countries around the world.
