Oppenheimer. Did he tell Groves the truth?

Robert Oppenheimer was at the time much closer to the Communist Party than he ever admitted. But as director of the laboratory that produced the atomic bomb, and as a weapons adviser to the American government after World War II, he served his country more honestly than many of those who questioned his loyalty. This fascinating paradox is at the heart of the most compelling and comprehensive historical study yet written of the domestic politics of the United States in the early years of the nuclear age. The study, "Brotherhood of," the Bomb was written by Greg Herken, a historian at the Smithsonian Institution.

Harken shows how high-ranking officials conspired, sometimes through illegal wiretapping, to remove Oppenheimer from government service in 1954 and forced a ground forces general to testify falsely that Oppenheimer was considered a security risk. In addition. Harken also demonstrates that Oppenheimer's petty lies about who told him what about potential Soviet espionage stemmed from personal loyalties more than political loyalties, and hurt him more than anyone else. The study includes more than 80 FBI interviews and documents, which were previously classified and recently declassified.

The "Brotherhood" appearing in the title of the book has a double meaning. It refers to the people mentioned in its subtitle - "The Complicated Lives and Loyalties of Robert Oppenheimer, Ernest Lawrence and Edward Teller". These giants of atomic physics were bound together for decades in complex and strained alliances, partly created by these individuals themselves, but often by military and political institutions that used them. Their actions were motivated by vanity, political dogma, interests, ambitions for power and perhaps also assessments of what they saw as the welfare and good of the United States, and the world as a whole.

The title of Harken's book also brings up the relationship between Robert Oppenheimer and his brother Frank, a physicist who Robert brought to the Manhattan Project, even though he was a member of the Communist Party between 1937 and 1941. Oppenheimer's contradictory reports about spies were later portrayed as intended to protect his brother. These lies exposed him to attack by people who wanted his downfall for other reasons, notably his opposition to specific weapons production initiatives supported in the early 1954s by Teller and the US Air Force. Teller, who eventually took Oppenheimer's place as the most influential adviser on nuclear weapons matters, testified in XNUMX that Oppenheimer should be stripped of any security clearance.

Harkan tells about the two "brotherhoods" in a fascinating plot that moves from Berkeley to Los Alamos and Washington and several other places where bombs were designed, tested and discussed. The University of California, Berkeley, was the academic home of Oppenheimer and Ernest Orlando Lawrence, an incredibly creative experimental physicist who won the Nobel Prize in 1939 for designing the cyclotron (particle accelerator). Lawrence was the first person the administration chose to run the Los Alamos laboratory. But his casual and relaxed approach to security practices prompted James Conant and VanVar Bush, the two senior White House science advisers, to rethink the issue.

Lawrence brought Oppenheimer to a committee of scientists to advise the administration on assembling the bomb,
and provided such wise and sharp advice regarding technical problems that it became essential
for the project. General Leslie Groves, the military officer in charge of the Manhattan Project,

But the contacts he had with Oppenheimer in 1942 convinced him of his honesty

However, Harken's research shows that Oppenheimer was close to the Communist Party

Groves to promise him that he would never reveal this to the FBI.

Oppenheimer provided the FBI with a different story about the espionage efforts, making no mention of the
Brother. He did mention others, including Hacon Chevalier, professor of French
in Berkeley, who he says served as an intermediary in the Soviet initiative.

Groves kept his promise, and even persistently defended Oppenheimer over the next decade. but
In 1943, an aide, whom Groves trusted and revealed to him about his conversation with, leaked

Potentially were they perhaps based on the awareness of the fact that his brother was indeed a spy?
Harkan did not find any evidence to confirm any answer to these questions.
