Passage: Gerhart Hass was born in Berlin roughly two years before the Nazis took power and transformed Germany into a one-party dictatorship. By the time he left school in 1949 half of Berlin and a large area surrounding the city were being administered as the Soviet occupation zone. He joined the Free German Youth ("Freie Deutsche Jugend" / FDJ), becoming a district secretary for what was in effect the youth wing of the ruling party in what was relaunched, in October of that year, as the German Democratic Republic, a new kind of one-party dictatorship. The next year Hass transferred to Berlin's Humboldt University and embarked on a degree course in History. After a year, however, in 1951 he was recommended for a transfer abroad. For five years he studied History at the Zhdanov University in Leningrad (as the Saint Petersburg State University was then known), and it was from Leningrad that he emerged in 1956 with a History Degree.
