Throughout the 1950s, the border between East and West Berlin remained fairly open. Many residents of East Berlin went back and forth to West Berlin. Othere did not come back and instead emigrated to West Germany. From 1949 to 1961, 2.6 million East Germans defected to the West via West Berlin. A large number of these emigrants were talented professionals and intellectuals, facilitating a sort of "brain drain" from the GDR. As the rate of defections rose to unbearable levels, the Communist leaders of Eastern Europe decided to put a stop to it. In early August 1961, members of the Comecon decided to seal the border between East and West Berlin. The SED leader Walter Ulbricht signed the order to seal the border on August 12, 1961. On the night of August 13, East German troops sealed the border, and construction began on a massive barrier that became known as the Berlin Wall (''Berliner Mauer''). | Throughout the 1950s, the border between East and West Berlin remained fairly open.
