Markus Johannes Wolf, also known as Mischa, was head of the Main Directorate for Reconnaissance, the foreign intelligence division of East Germany's Ministry for State Security. 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 best-known spymasters during the Cold War. In the West he was known as "the man without a face" due to his elusiveness.

Friedrich Wolf was a German doctor and politically-engaged writer. From 1949 to 1951, he served as East Germany's first ambassador to Poland.
