Abstract: After World War II, Germany was split into four occupation zones, from which two states arose in 1949: West Germany (officially called FRG) and East Germany (officially GDR). East Germany was under Soviet control until 1989. In both states, computer chess and chess computers followed interesting, but rather different paths. We give an overview of East German developments: on commercial chess computers, problem chess programs, the book of 1987, the Serfling tournaments, and correspondence chess pioneer Heinrich Burger. There exist important interrelations between topics. The starting point is a short description of the Cold War situation with its harsh economic consequences for the socialist states, including East Germany.
