Markus Johannes Wolf (19 January 1923 – 9 November 2006), also known as Mischa, was head of the Main Directorate for Reconnaissance (Hauptverwaltung Aufklärung), the foreign intelligence division of East Germany's Ministry for State Security (Ministerium für Staatssicherheit, abbreviated MfS, commonly known as the Stasi). He was the Stasi's number two for 34 years, which spanned most of the Cold War. He is often regarded as one of the most well-known spymasters during the Cold War. In the West he was known as "the man without a face" due to his elusiveness.
