In 1945 she joined the Communist Party ( KPD ) , and in April 1946 she was among the thousands of communists who lost no time in signing their party membership across to the new Socialist Unity Party ( '' " Sozialistische Einheitspartei Deutschlands " '' / SED ) , which by October 1949 would have become the ruling party in a new kind of German one-party dictatorship . Between 1946 and 1948 she also represented the KPD/SED party on the Berlin city council ( '' " Stadtverordnetenversammlung " '' ) . In 1948 she was dismissed from her position at the " Urban Hospital " ( '' " Urban-Krankenhaus " '' ) . The division of Berlin into military occupation zones agreed in 1945 was by now acquiring a level of permanence that few would have anticipated three years earlier , and she now relocated from the American occupation zone to the Soviet occupation zone , taking a post as a senior internist at the Charité ( hospital ) . Her move was attributed , by the West German pro-Western news magazine , Der Spiegel , to " Communist activities " ( '' " Wegen Kommunistischer Umtriebe " '' )
