Edward Joseph Snowden is a former National Security Agency (NSA) intelligence contractor and whistleblower who leaked classified documents revealing the existence of global surveillance programs.
Born in 1983 in Elizabeth City, North Carolina, he attended a community college and later enrolled in a master's programme at the University of Liverpool without finishing it. In 2006 he started working for the Central Intelligence Agency (CIA) and then switched to Dell in 2009, where he managed computer systems for the NSA. In 2013, he worked for two months at Booz Allen Hamilton, with the purpose of gathering more NSA documents.
In May 2013, Snowden flew to Hong Kong, and in early June he revealed thousands of classified NSA documents to journalists Glenn Greenwald, Laura Poitras, Barton Gellman, and Ewen MacAskill.
