[88] In August 1943, he volunteered to Manhattan Project security agents that George Eltenton, whom he did not know, had solicited three men at Los Alamos for nuclear secrets on behalf of the Soviet Union. [109] After a mammoth research effort, the more complex design of the implosion device, known as the "Christy gadget" after Robert Christy, another student of Oppenheimer's,[110] was finalized in a meeting in Oppenheimer's office on February 28, 1945. He lives contently in seclusion. [60] Oppenheimer was nominated for the Nobel Prize for physics three times, in 1946, 1951 and 1967, but never won. In return he was asked to curtail his teaching at Caltech, so a compromise was reached whereby Berkeley released him for six weeks each year, enough to teach one term at Caltech. [157] This new design seemed technically feasible and Oppenheimer officially acceded to the weapon's development,[158] while still looking for ways in which its testing or deployment or use could be questioned. [34], On returning to the United States, Oppenheimer accepted an associate professorship from the University of California, Berkeley, where Raymond T. Birge wanted him so badly that he expressed a willingness to share him with Caltech.[31]. [124] In October 1945, Oppenheimer was granted an interview with President Harry S. Truman. [197] Oppenheimer chose not to resign and requested a hearing instead. Shortly thereafter, the FBI added Oppenheimer to its Custodial Detention Index, for arrest in case of national emergency. Born left it out on his desk where Oppenheimer could read it, and it was effective without a word being said. He was an iconic figure to his fellow scientists, as much a symbol of what they were working toward as a scientific director. [196] On December 21, 1953, Strauss told Oppenheimer that his security clearance had been suspended, pending resolution of a series of charges outlined in a letter, and discussed his resigning by way of requesting termination of his consulting contract with the AEC. "[105], In 1943 development efforts were directed to a plutonium gun-type fission weapon called "Thin Man". Jack was born on September 2 1890, in Hemsbach, Baden-Wrttemberg, Germany. [250] One group viewed with passionate fear the Soviet Union as a mortal enemy and believed having the most powerful weaponry capable of providing the most massive retaliation was the best strategy for combating that threat. [20], Oppenheimer was a tall, thin chain smoker,[21] who often neglected to eat during periods of intense thought and concentration. He argued that they would have to have the same mass as an electron, whereas experiments showed that protons were much heavier than electrons. [202] A transcript of the hearings was published in June 1954,[203] with some redactions. [264][265] The Day After Trinity, a 1980 documentary about J. Robert Oppenheimer and the building of the atomic bomb, was nominated for an Academy Award and received a Peabody Award. [70], Their first child, Peter, was born in May 1941,[71] and their second, Katherine ("Toni"), was born in Los Alamos, New Mexico, on December 7, 1944. I suppose we all thought that, one way or another.[3]. [142], The first atomic bomb test by the Soviet Union in August 1949 came earlier than Americans expected, and over the next several months there was an intense debate within the U.S. government, military, and scientific communities over whether to proceed with the development of the far more powerful, nuclear fusion-based hydrogen bomb, then known as "the Super". [79] He was a subscriber to the People's World,[80] a Communist Party organ, and he testified in 1954, "I was associated with the communist movement. [134] He collected European furniture, and French post-impressionist and Fauvist artworks. Robert Oppenheimer, "Prospects in the Arts and Sciences" in Man's Right to Knowledge[222], Starting in 1954, Oppenheimer lived for several months of the year on the island of Saint John in the U.S. Virgin Islands. He always knew what were the important problems, as shown by his choice of subjects. Oppenheimer made friends who went on to great success, including Werner Heisenberg, Pascual Jordan, Wolfgang Pauli, Paul Dirac, Enrico Fermi and Edward Teller. In one incident, his damning testimony against former student Bernard Peters was selectively leaked to the press. Soviet intelligence tried repeatedly to recruit him, but was never successful; Oppenheimer did not spy on the United States. [236][237] At the urging of many of Oppenheimer's political friends who had ascended to power, President John F. Kennedy awarded Oppenheimer the Enrico Fermi Award in 1963 as a gesture of political rehabilitation. He opposed the development of the hydrogen bomb during a 19491950 governmental debate on the question and subsequently took stances on defense-related issues that provoked the ire of some U.S. government and military factions. [111], In May 1945 an Interim Committee was created to advise and report on wartime and postwar policies regarding the use of nuclear energy. After World War II, Oppenheimer published only five scientific papers, one of which was in biophysics, and none after 1950. All these, in different ways, were turned against him in the hearings. He met this group once a day in his office and discussed with one after another the status of the student's research problem. According to the historian Gregg Herken, this naming could have been an allusion to Jean Tatlock, who had committed suicide a few months before and had in the 1930s introduced Oppenheimer to Donne's work. [47] Oppenheimer, drawing on the body of experimental evidence, rejected the idea that the predicted positively charged electrons were protons. The pessimist fears it is true. [211] Many top scientists, as well as government and military figures, testified on Oppenheimer's behalf. He truly lived with those problems, struggling for a solution, and he communicated his concern to the group. [87] Tatlock committed suicide on January 4, 1944, leaving Oppenheimer deeply grieved. W hen J Robert Oppenheimer first saw the awful power of the atomic bomb, in the Trinity test at Los Alamos, New Mexico, in 1945, he was reminded of the words in the Bhagavad Gita, "Now I am become . "[216], In a seminar at The Wilson Center in 2009, based on an extensive analysis of the Vassiliev notebooks taken from the KGB archives, John Earl Haynes, Harvey Klehr and Alexander Vassiliev confirmed that Oppenheimer never was involved in espionage for the Soviet Union. father: Julius Oppenheimer mother: Ella Friedman siblings: Frank Oppenheimer children: Katherine Oppenheimer, Peter Oppenheimer Quotes By J. Robert Oppenheimer Physicists Died on: February 18, 1967 place of death: Princeton, New Jersey, United States Ancestry: German American Notable Alumni: Christ's College, Cambridge Grouping of People: Smoker He noted his regret the weapon had not been available in time to use against Nazi Germany. Oppenheimer respected and liked Pauli and may have emulated his personal style as well as his critical approach to problems. Los Alamos, NM. [37] His students almost always fell into the former category, adopting his walk, speech, and other mannerisms, and even his inclination for reading entire texts in their original languages. Here his uncanny speed in grasping the main points of any subject was a decisive factor; he could acquaint himself with the essential details of every part of the work. He was hired by a textile company and within a decade was an executive there, eventually becoming wealthy. He was noted for his mastery of all scientific aspects of the project and for his efforts to control the inevitable cultural conflicts between scientists and the military. Robert Leonard Oppenheimer was born on month day 1925, at birth place, Illinois, to Jack M Oppenheimer and Mabel OPPENHEIMER (born Solomon). The two had similar political views; she wrote for the Western Worker, a Communist Party newspaper. Fergusson noticed that Oppenheimer was not well. [166] Oppenheimer was also a member of the Science Advisory Committee of the Office of Defense Mobilization. After reading a transcript of Kipphardt's play soon after it began to be performed, Oppenheimer threatened to sue the playwright, decrying "improvisations which were contrary to history and to the nature of the people involved". [230], In his speeches and public writings, Oppenheimer continually stressed the difficulty of managing the power of knowledge in a world in which the freedom of science to exchange ideas was more and more hobbled by political concerns. [133] The job came with a salary of $20,000 per annum, plus rent-free accommodation in the director's house, a 17th-century manor with a cook and groundskeeper, surrounded by 265 acres (107ha) of woodlands. [13] Oppenheimer was a versatile scholar, interested in English and French literature, and particularly in mineralogy. His work predicted many later finds, which include the neutron, meson and neutron star. J. Robert Oppenheimer. [57] An asteroid, 67085 Oppenheimer, was named in his honor,[275] as was the lunar crater Oppenheimer. [159] As he later recalled: The program we had in 1949 was a tortured thing that you could well argue did not make a great deal of technical sense. In the summer of 1940, she stayed with Oppenheimer at his ranch in New Mexico. J. Robert Oppenheimer[note 1] (/pnhamr/; April 22, 1904 February 18, 1967) was an American theoretical physicist. Because of the threat fascism posed to Western civilization, they volunteered in great numbers both for technological and organizational assistance to the Allied effort, resulting in such powerful tools as radar, the proximity fuse and operations research. Oppenheimer rejected the idea of nuclear gunboat diplomacy. [33] From Leiden he continued on to the Swiss Federal Institute of Technology (ETH) in Zurich to work with Wolfgang Pauli on quantum mechanics and the continuous spectrum. [272] His papers are in the Library of Congress. Significantly, after his public humiliation, he did not sign the major open protests against nuclear weapons of the 1950s, including the RussellEinstein Manifesto of 1955, nor, though invited, did he attend the first Pugwash Conferences on Science and World Affairs in 1957. I said that perhaps he [Kipphardt] had forgotten Guernica, Coventry, Hamburg, Dresden, Dachau, Warsaw, and Tokyo; but I had not, and that if he found it so difficult to understand, he should write a play about something else. [214] As it happened, Oppenheimer was seen by most of the scientific community as a martyr to McCarthyism, an eclectic liberal who was unjustly attacked by warmongering enemies, symbolic of the shift of scientific creativity from academia into the military. While Fergusson's account is the only detailed version of this event, Oppenheimer's parents were alerted by the university authorities who considered placing him on probation, a fate prevented by his parents successfully lobbying the authorities. Unable to find work in physics for many years, he became a cattle rancher in Colorado. For more information on Peter Oppenheimer's life, read American Prometheus by Kai Bird and Martin Sherwin. For the last few seconds, he stared directly ahead and then when the announcer shouted "Now!" [225][226] He had been selected for the final episode of the lecture series two years prior to the security hearing, though the university remained adamant that he stay on even after the controversy. He calculated the photoelectric effect for hydrogen and X-rays, obtaining the absorption coefficient at the K-edge. He graduated summa cum laude in three years. This was after a paper by Paul Dirac proposed that electrons could have both a positive charge and negative energy. [64], Oppenheimer's mother died in 1931, and he became closer to his father who, although still living in New York, became a frequent visitor in California. Heinar Kipphardt's play In the Matter of J. Robert Oppenheimer, after appearing on West German television, had its theatrical release in Berlin and Munich in October 1964. Under Oppenheimer's direction, physicists tackled the greatest outstanding problem of the pre-war years: infinite, divergent, and nonsensical expressions in the quantum electrodynamics of elementary particles. [70] During his marriage, Oppenheimer rekindled his affair with Tatlock. Bridgman also wanted him at Harvard, so a compromise was reached whereby he split his fellowship for the 192728 academic year between Harvard in 1927 and Caltech in 1928. [246] She left the property to "the people of St. John for a public park and recreation area". He then suggested and championed a site that he knew well: a flat mesa near Santa Fe, New Mexico, which was the site of a private boys' school, the Los Alamos Ranch School. [259] It premiered in New York in June 1968, with Joseph Wiseman in the Oppenheimer role. Oppenheimer delivered the Reith Lectures on the BBC in 1953, which were subsequently published as Science and the Common Understanding. [180] But the panel lacked political allies in Washington, and the Ivy Mike shot went ahead as scheduled. [238] A little over a week after Kennedy's assassination, his successor, President Lyndon Johnson, presented Oppenheimer with the award, "for contributions to theoretical physics as a teacher and originator of ideas, and for leadership of the Los Alamos Laboratory and the atomic energy program during critical years". [96] But he was impressed by Oppenheimer's singular grasp of the practical aspects of designing and constructing an atomic bomb and by the breadth of his knowledge. [56], In spite of this, observers such as Nobel Prize-winning physicist Luis Alvarez have suggested that if he had lived long enough to see his predictions substantiated by experiment, Oppenheimer might have won a Nobel Prize for his work on gravitational collapse, concerning neutron stars and black holes. [63] He once remarked that he never cast a vote until the 1936 presidential election. These enemies included Strauss, an AEC commissioner who had long harbored resentment against Oppenheimer both for his activity in opposing the hydrogen bomb and for his humiliation of Strauss before Congress some years earlier; regarding Strauss's opposition to the export of radioactive isotopes to other nations, Oppenheimer had memorably categorized these as "less important than electronic devices but more important than, let us say, vitamins". This led to Cecil Frank Powell's breakthrough and subsequent Nobel Prize for the discovery of the pion. He was fond of using elegant, if extremely complex, mathematical techniques to demonstrate physical principles, though he was sometimes criticized for making mathematical mistakes, presumably out of haste. [185], Thus by 1953, Oppenheimer had reached another peak of influence, being involved in multiple different government posts and projects and having access to crucial strategic plans and force levels. He developed a method to carry out calculations of its transition probabilities. While on vacation, as recalled by his friend Francis Fergusson, Oppenheimer once confessed that he had left an apple doused with noxious chemicals on Blackett's desk. [77][192], The triggering event for the security hearing happened on November 7, 1953,[193] when William Liscum Borden, who until earlier in the year had been the executive director of the United States Congress Joint Committee on Atomic Energy, sent Hoover a letter saying that "more probably than not J. Robert Oppenheimer is an agent of the Soviet Union. "[119] Farrell summarized Robert's reaction as follows: Dr. Oppenheimer, on whom had rested a very heavy burden, grew tenser as the last seconds ticked off. He donated to many progressive causes that were branded as left-wing during the McCarthy era. [136], During a series of conferences in New York from 1947 through 1949, physicists switched back from war work to theoretical issues. [65] When his father died in 1937, leaving $392,602 to be divided between Oppenheimer and his brother Frank, Oppenheimer immediately wrote out a will that left his estate to the University of California to be used for graduate scholarships. The German Jewish philosopher Moses Mendelssohn and his brother Saul were the first to adopt the surname Mendelssohn. He eventually read the Bhagavad Gita and the Upanishads in the original Sanskrit, and deeply pondered them. New York, NY, United States. [120], Rabi noticed Oppenheimer's disconcerting triumphalism: "I'll never forget his walk; I'll never forget the way he stepped out of the car his walk was like High Noon this kind of strut. [231] In 1955, Oppenheimer published The Open Mind, a collection of eight lectures that he had given since 1946 on the subject of nuclear weapons and popular culture. Though she refused and reported the incident to her husband,[30] the invitation, and her apparent nonchalance about it, disquieted Pauling and he ended his relationship with Oppenheimer. Moreover, in terms of the time, effort and money spent on party activities, he was a very committed supporter". After inconclusive surgery, he underwent unsuccessful radiation treatment and chemotherapy late in 1966. [72] Later their continued contact became an issue in his security clearance hearings, because of Tatlock's communist associations. He was followed by Army security agents during a trip to California in June 1943 to visit his former girlfriend, Jean Tatlock, who was suffering from depression. The issues became purely the military, the political and the humane problem of what you were going to do about it once you had it. Oppenheimer attended the Ethical Culture School in New York. Abraham Pais said that Oppenheimer himself thought that one of his failures at the institute was being unable to bring together scholars from the natural sciences and the humanities. Bridgman provided Oppenheimer with a recommendation, which conceded that Oppenheimer's clumsiness in the laboratory made it apparent his forte was not experimental but rather theoretical physics. I remembered the line from the Hindu scripture, the Bhagavad Gita; Vishnu is trying to persuade the Prince that he should do his duty and, to impress him, takes on his multi-armed form and says, "Now I am become Death, the destroyer of worlds." and there came this tremendous burst of light followed shortly thereafter by the deep growling roar of the explosion, his face relaxed into an expression of tremendous relief. Death: February 18, 1967 (62) Princeton, NJ, United States (Throat Cancer) Place of Burial: Cremated, (ashes scattered over the Virgin Islands) Immediate Family: Son of Julius Seligmann Oppenheimer and Ella Oppenheimer. [14] He completed the third and fourth grades in one year and skipped half of the eighth grade. 140: 161-3. Rutherford was unimpressed, but Oppenheimer went to Cambridge in the hope of landing another offer. In 1935, Oppenheimer and Phillips worked out a theorynow known as the OppenheimerPhillips processto explain the results; this theory is still in use today. In this interview with historian Kai Bird, author of American Prometheus, a biography of J.. He jumped on Fergusson and tried to strangle him. He never openly joined the Communist Party USA (CPUSA), though he did pass money to leftist causes by way of acquaintances who were alleged to be party members. His father, Julius Oppenheimer, was a German immigrant who worked in his family's textile importing business. When he refused, she obtained an instant divorce in Reno, Nevada, and took Oppenheimer as her fourth husband on November 1, 1940. He directed and encouraged the research of many well-known scientists, including Freeman Dyson, and the duo of Chen Ning Yang and Tsung-Dao Lee, who won a Nobel Prize for their discovery of parity non-conservation. [188] He had been under close surveillance since the early 1940s, his home and office bugged, his phone tapped and his mail opened. [269] In the upcoming American film Oppenheimer, directed by Christopher Nolan and based on American Prometheus, Oppenheimer is portrayed by actor Cillian Murphy. In the first of these, a 1938 paper co-written with Robert Serber titled "On the Stability of Stellar Neutron Cores",[49] Oppenheimer explored the properties of white dwarfs. Many of his friends said he had self-destructive tendencies. In 1933, he learned Sanskrit and met the Indologist Arthur W. Ryder at Berkeley. I remembered the line from the Hindu scripture, the Bhagavad-Gita. He was interested in everything, and in one afternoon they might discuss quantum electrodynamics, cosmic rays, electron pair production and nuclear physics. [12] During his final year, he became interested in chemistry. [91] In May 1942, National Defense Research Committee Chairman James B. Conant, who had been one of Oppenheimer's lecturers at Harvard, invited Oppenheimer to take over work on fast neutron calculations, a task Oppenheimer threw himself into with full vigor. In its presentation to the Interim Committee, the scientific panel offered its opinion not just on the likely physical effects of an atomic bomb, but on its likely military and political impact. [266][267] Oppenheimer's life has also been explored in the 2015 play Oppenheimer by Tom Morton-Smith,[268] and in the 1989 film Fat Man and Little Boy, where he was portrayed by Dwight Schultz. She finally asked Harrison for a divorce when she found out she was pregnant. Among those present with Oppenheimer in the control bunker at the site were his brother Frank and Brigadier General Thomas Farrell. They strongly suspected that he himself was a member of the party, based on wiretaps in which party members referred to him or appeared to refer to him as a communist, as well as reports from informers within the party. He was surprised on the witness stand with transcripts of these, which he had not been given a chance to review. [94] In September, Groves was appointed director of what became known as the Manhattan Project. From 1934 on, however, he became increasingly concerned about politics and international affairs. [161] Truman had declined to reappoint them, as he wanted new voices on the committee who were more in support of H-bomb development. Isidor Rabi considered the appointment "a real stroke of genius on the part of General Groves, who was not generally considered to be a genius". He compensated for his late start by taking six courses each term and was admitted to the undergraduate honor society Phi Beta Kappa. Fromet Mendelssohn ne Guggenheim. Oppenheimer repeatedly attempted to get Serber a position at Berkeley but was blocked by Birge, who felt that "one Jew in the department was enough". When he heard the ranch was available for lease, he exclaimed, "Hot dog! [179] The panel then issued a final report in January 1953, which, influenced by many of Oppenheimer's deeply felt beliefs, presented a pessimistic vision of the future in which neither the United States nor the Soviet Union could establish effective nuclear superiority but both sides could effect terrible damage on the other. The FBI noted that Oppenheimer was on the Executive Committee of the American Civil Liberties Union, which it considered a communist front organization. [101] It soon turned out that Oppenheimer had hugely underestimated the magnitude of the project; Los Alamos grew from a few hundred people in 1943 to over 6,000 in 1945.[100]. To this extent I feel that I would like to see the vital interests of this country in hands which I understand better, and therefore trust more. In its heyday, there were about eight or ten graduate students in his group and about six Post-doctoral Fellows. [166] Undertaken at the MIT Lincoln Laboratory, which had recently been founded to study issues of air defense, this in turn led to the Lincoln Summer Study Group, where Oppenheimer became a key figure.
