Because he realized what a horrificly powerful weapon nuclear bombs actually are & he decided to compaign against the use of them after they were used in Japan.
Robert Oppenheimer lost his security clearance because of his wife's alleged connections with Communist organizations.
Oppenheimer had the codename James Oberhelm; Fermi's name was Henry Farmer; and Hans Bethe was Howard Battle.
Good question, I am searching for the same thing. In reading the notes from American Prometheus, he was living in Northern New Mexico until the '80s. I'm pretty sure the VP at Apple is not the same.

"I am become death, the destroyer of worlds."
Now I am become Death: Destroyer of worlds.
J. Robert Oppenheimer is not really the only "father" of the atomic bomb. Although his research and discoveries were significant, the bomb could have been invented in about the same time if he had not been part of the Manhattan Project. His fellow scientists remembered him as a visionary and capable leader at Los Alamos, while his security hearing brought to light foolish mistakes in judgment and human relationships.
J. Robert Oppenheimer led the scientific efforts which produced the first atomic bomb for the United States, in 1945. Despite his brilliant achievements at the Manhattan Project, Oppenheimer's misgivings about atomic weaponry in general led to his isolation from government weapons research in the years following the war.
After witnessing the first test at Trinity, Oppenheimer wrote that some laughed, some cried, and through his mind floated a line from the Bhagavadgita: "I am become death: the destroyer of worlds." His ambivalance towards the use of science for military ends led to his opposition to the development of a hydrogen bomb after the war. Unfortunately for him, the Soviet Union exploded its own atomic weapon in 1948, creating tremendous pressure for the US to develop the even larger fusion weapon.
You mean Rene Robert Cavalier Sieur de La Salle. He was famous for exploring up and down the Mississippi River for France
It's pretty convoluted, but the short answer is that they thought he might be a Soviet spy.
Oppenheimer had, when younger, had some friends and acquaintances who were communists. He had drifted apart from most of these, but was still on fairly good terms with at least one of them. A Soviet agent approached his friend, and that friend spoke with Oppenheimer about it. Very briefly and casually; it was something along the lines of "So-and-so was wondering if there anything you can do to make sure the Soviets are kept in the loop, perhaps unofficially?" and Oppenheimer's response was something along the lines of "No, that's not how to do these things."
The problem was that when Oppenheimer reported this to his superiors, he didn't report it accurately and tried to hide his own involvement and that of his friend. He just said that "some people" had been approached on behalf of the Soviets. So the US started a big spy hunt for these Soviet agents, and Oppenheimer's responses to their questions weren't adding up. In fact, he wound up making things a lot worse for his friend than was actually justified, because the Government already suspected both Oppenheimer and his friend based on their (known) past association with communists, and Oppenheimer trying to cover it up made it look as if their involvement had been much more sinister than it really was.
1945... Secretary of War Stimson, visiting my headquarters in Germany, informed me that our government was preparing to drop an atomic bomb on Japan. I was one of those who felt that there were a number of cogent reasons to question the wisdom of such an act. ...the Secretary, upon giving me the news of the successful bomb test in New Mexico, and of the plan for using it, asked for my reaction, apparently expecting a vigorous assent.
"During his recitation of the relevant facts, I had been conscious of a feeling of depression and so I voiced to him my grave misgivings, first on the basis of my belief that Japan was already defeated and that dropping the bomb was completely unnecessary, and secondly because I thought that our country should avoid shocking world opinion by the use of a weapon whose employment was, I thought, no longer mandatory as a measure to save American lives. It was my belief that Japan was, at that very moment, seeking some way to surrender with a minimum loss of 'face'. The Secretary was deeply perturbed by my attitude..."

Oppenheimer was the scientist/manager who directed the team that built the tool
and made it work. The final decision on what to do with it and when was made by
the Commander in Chief of the Armed Forces ... President Truman.

Yes, J. Robert Oppenheimer, an American theoretical physicist and one of the key figures in the development of the atomic bomb during World War II, had his security clearance revoked in 1954, which effectively stripped him of his ability to work on classified projects. While his security clearance was revoked, his citizenship was not taken away.
