Introduction 0)( THE MORNING of April 12, 1954, readers of the New York Times ----0 ce to startling news. The security clearance of the nation's best- -'=lown nuclear scientist, J. Robert Oppenheimer, had been sus- ?Ended in the face of charges that he was a security risk. The Timess scoop created a sensation, for Oppenheimer was a na- "':onalhero. He had been the leader of the Manhattan Project during -odd War II, and his name, more than that of any other American, -='2S coupled with the building of the atomic bomb and the war's ~ orious end at Hiroshima and Nagasaki. After the war, as the gov- emrnent's number one adviser on atomic weapons, he had been privy :0 all its decisions about these weapons. If Oppenheimer was a secu- ziry risk, did the United States have a single important secret left? It was almost unthinkable that this man's loyalty should be in question. Except that as U.S. disagreement with the Soviet Union Jafdened into a state of permanent tension, the certainties that had sustained the American people during the war and the early years zhereafter ebbed away, and so did some of the nation's confidence. _-\frerthe defections of two people who had spied for the USSR (a So- +ier code clerk in Canada named Igor Gouzenko in 1946 and a "oman named Elizabeth Bentley from the U.S. Communist Party in =948), Americans learned that key parts of the government-State, -:::-reasury,and possibly even the White House-had been penetrated ~y Soviet agents.
