Vladimir Vetrov

Vladimir Ippolitovich Vetrov (Russian: Владимир Ипполитович Ветров; 10 October 1932 – 23 January 1985) was a high-ranking KGB spy during the Cold War who decided to covertly release valuable information, later known as the Farewell Dossier, to France and NATO on the Soviet Union's clandestine program aimed at stealing technology from the West.

Vetrov was assigned the code-name Farewell by the French intelligence service the Direction de la surveillance du territoire (DST), which recruited him. He was known by that name throughout NATO's intelligence services. The code-name was chosen as an English word, so that the KGB would assume he worked for the CIA if it learned his codename.

Vetrov was executed for treason in the Soviet Union on 23 January 1985. His life inspired a film and books were written about his life and career.
