Markus Wolf
Markus Johannes "Mischa" Wolf (19 January 1923 – 9 November 2006) was head of the General Intelligence Administration (Hauptverwaltung Aufklärung), the foreign intelligence division of East Germany's Ministry for State Security (MfS, commonly known as the Stasi). He was the MfS's number two for 34 years, which spanned most of the Cold War. Many intelligence experts[weasel words] regard him as one of the greatest spymasters of all time.
