Robert Oppenheimer was born in America on April 22, 1904New YorkA rich German Jewish family, he dabbled in literature, philosophy, language and other fields when he was young, and initially received education in the Alcuin Preparatory School.
In 1911, he entered the Ethical Culture Fieldstone School in New York, completed the third and fourth grades in one year, and skipped a semester of the eighth grade[2]。
In 1921, he graduated from Feldstone School of Arts and Sciences with ten honors;In the same year, due toCzechoslovakia's family contracted colitis during their vacation, and laterNew MexicoRehabilitated, thus delaying the entrance to university for one year.
In 1922, he entered the chemistry department of Harvard University to study[32], was admitted by the Phi Beta Kappa during his undergraduate period, and obtained the physics graduate qualification on the basis of independent study.
In 1925, he graduated from Harvard University in advance as an honorary student;In the same year, I went to Cambridge University in England for further studyErnest Rutherford Ernest Rutherford was engaged in experimental physics research, but Ernest Rutherford was unwilling to accept him as a student, so he began to study theoretical physics and joinedCavendish Laboratory Cavendish LaboratoryJoseph John Thomson (Joseph John Thomson)。
In 1926, it was transferred to GermanyUniversity of Gottingen(George August-Universit ä t G ö ttingen), followMax Born (Max Born) engaged in research.
In 1927, he graduated from the University of Gottingen in Germany and obtained a doctor's degree in physicsZurich(Z ü rich) and Leiden in the Netherlands.
In the summer of 1929, he returned to the United States and was infectedpulmonary tuberculosis, recuperate on a farm near Los Alamos, New Mexico;In the same year, enteringUniversity of California, Berkeley(University of California, Berkeley) taught and founded the "Oppenheimer Center for Theoretical Physics".
Oppenheimer and Yang Zhenning
In 1941, he was elected as a member of the National Academy of Sciences.
In August 1942, he was appointed to develop the atomic bomb“Manhattan Project (Manhattan Project).
In 1943, he presided over the establishment of the Los Alamos Laboratory in the desert of New Mexico and served as the director. Edward Teller assisted Robert Oppenheimer in organizing the team working in Los Alamos[3]。
In July 1945, he led the production of the world's first atomic bomb;In October, he resigned as the director of Los Alamos Laboratory[30]After that, he briefly taught at the California Institute of Technology.
In 1954,Dwight David Eisenhower (Dwight David Eisenhower) "indicted him on the charge of his early leftist activities and delaying the government's strategic decision to develop the hydrogen bomb, and even suspected that he was an agent of the Soviet Union", reviewed Robert Oppenheimer's security and revoked his security franchise[10]。
In 1965, he suffered from hepatitis and was in poor health.
In 1966, he retired from Princeton Institute of Advanced Studies and soon found thatCarcinoma of upper larynx[30]。
On February 18, 1967, he died of throat cancer in Princeton, New Jersey, at the age of 62. He was cremated and his ashes were scatteredBritish Virgin Islands(The British Virgin Islands)[7]。

Scientific research achievements
Overview of scientific research
Robert Oppenheimer has done some work in theoretical astronomy, nuclear physics, spectroscopy and quantum field theory (including quantum electrodynamics).He andMax Born Wave proposed Born Oppenheimer approximation to describe molecular wave functions[23]。
Robert Oppenheimer's initial research focus was the continuous spectrum theory. His first paper published in 1926 was the quantum theory of molecular spectrum.He invented a method to calculate the energy level transition probability, and applied it to the electro-optic effect phenomenon of hydrogen emitting X-ray, and calculated the absorption coefficient of the K edge.The calculated results of hydrogen are consistent with the X-ray absorption spectrum of the sun, but the calculated results of helium are not consistent.Scientists found that the main component of the sun is hydrogen years later, which means his calculations have always been correct[24]。
Robert Oppenheimer has done some work on the theory of cosmic rays, and has begun to describe the quantum tunneling effect.In 1931, he and student Harvey Hall published the Quantum Theory of Electro optical Effect, which correctly overturned Dirac's claim that two energy levels of hydrogen atom have the same energy through experimental evidence[25]。
Robert Oppenheimer and his doctoral student Melba Phillips calculated the artificial radioactivity produced by deuteron bombardment.In 1935, they came up with a more powerful new theory called Oppenheimer Phillips process[26]。
At the end of 1930, Robert Oppenheimer began to study astrophysics. In 1938, he and Robert Thurber jointly published "On the Stability of Neutron Stellar Nuclei", which discussed the properties of white dwarfs[27]。Then, he and student George Volkov published On the Nucleus of Large Mass Neutron Stars, which proved that a stable neutron star has a certain mass limit, and once it exceeds, it will collapse gravitationally, which is the so-called Tolman Oppenheimer Volkov[29]。In 1939, he and student Hartland Snyder published On the Continuous Gravitational Attraction to predict the existence of black holes[28]。
When Robert Oppenheimer was the director of the Manhattan Program, in addition to dealing with macro strategic and specific tactical issues, he also directed more than 3000 people to conduct top secret research in different locations[5]。

Oppenheimer case
191950smccarthyismRobert Oppenheimer became more and more suspicious because he knew several communists in the 1930s, and some of his friends were identified as Soviet agents in an investigation in 1942, in addition to opposing the manufacture of hydrogen bombs.In 1952, the Atomic Energy Commission of the United States prepared a document on Oppenheimer's suspected suspicious activities, and in December sent a representative to delete all secret documents related to the General Advisory Committee of the Atomic Energy Commission of the United States from Robert Oppenheimer's Princeton office.
In December 1953,American Atomic Energy CommissionIn the security hearing, it was announced that he had no treason, but it was ruled that he should not contact military secrets, and he was terminated as an adviser to the Atomic Energy Commission of the United States.
In June 1954, he was revoked his security clearance on the grounds of "fundamental defects of character" and that since 1942, he had "far exceeded the tolerance limit of prudence and self-restraint expected by those holding senior positions" in the Communist Association(far beyond the tolerable limits of prudence and self-restraint which are to be expected of one holding the high positions)[10]。
The American Federation of Scientists protested against his review and believed that he wasmccarthyismA victim of.John Kennedy(John Kennedy), after becoming President, proposed that he issue“Fermi Award(Fermi Award), and decided to award him the 1963 Fermi Award and attend the ceremony in person.But John Kennedy was assassinated in Dallas, Texas, on November 23, 1963, 10 days before the ceremony[11]。Succession to PresidentLyndon Baines Johnson (Lyndon Baines Johnson) awarded Oppenheimer a Fermi Prize and a prize of 50000 dollars in the same year, but it was only a formal restoration of reputation, and he was still not allowed to intervene in military secrets[12]。
