Julius Robert Oppenheimer was the scientific head of the U.S. atomic-bomb project during World War II. Oppenheimer was a brilliant physicist whose contributions were essential for the successful development of the atomic bomb. Despite his outstanding performance in the Manhattan Project, Robert Oppenheimer’s reputation has been tainted by allegations that he knowingly passed secrets of the atomic bomb to Soviet agents. This article discusses the possible truth of these allegations.
Tensions between the three victorious western powers and the Soviet Union had always existed. But the Cold War between the U.S. and the Soviet Union broke out “officially,” when Stalin decided in 1948 to blockade the three western sectors of Berlin; it ended in 1989, when the German people decided to tear down the Berlin wall. Papers listed in this section deal with this post-war era, which was, in a way, foreseen by Goebbels in February 1945, when he stated that a Soviet iron curtain would descend across Europe.
