J Robert Oppenheimer - Schöpfer der ersten Atombombe
Robert Oppenheimers Vater Julius S. Begonnen hatte diese Hexenjagd vor genau 60 Jahren.
Vor 60 Jahren begann in den USA die Hexenjagd auf den "Vater der Atombombe", J. Robert Oppenheimer - ausgelöst durch den Streit über. J. Robert Oppenheimer leitete das geheime militärische Forschungsunternehmen in Los Alamos und gilt daher als der "Vater der Atombombe". Wie kam ein. J. Robert Oppenheimer (–) war ein amerikanischer theoretischer Physiker deutsch-jüdischer Abstammung. Er gilt als «Vater der. They separated in June , and Kitty went to live with her parents in Claygate, where she found some work as a German-to-English translator.
She disappeared one day over the side of a transatlantic ship, and nobody missed her. That says it all. After a few days there, she returned to London, and they headed south, to cross into Spain [12] where he joined the Mackenzie-Papineau Battalion , a unit made up of American and Canadian volunteers.
Kitty wanted to join Dallet in Spain, and finally secured permission to do so; but her trip to Spain was delayed by her hospitalization for an operation on 26 August for what was initially thought to be appendicitis , but which was determined to be ovarian cysts , which were removed by the German doctors.
Kitty returned to England to recuperate. Before she could set out for Spain, the news arrived that Dallet had been killed in action on 17 October Kitty went to see Nelson, who was in Paris, having been wounded in August, and they returned to New York, where she stayed with Nelson and his wife Margaret at their home in Brooklyn for two months.
Kitty enrolled at the University of Pennsylvania. It was there that she met Richard Stewart Harrison, a medical doctor with degrees from Oxford University , who was completing his internship in the United States.
They were married on 23 November Soon after, Harrison left for Pasadena , California, for his residency at the California Institute of Technology Caltech , while Kitty completed her bachelor's degree in botany at the University of Pennsylvania, and was offered a postgraduate research fellowship at the University of California, Los Angeles.
It was at a garden party thrown by Lauritsen and his wife Sigrid in August that Kitty met Robert Oppenheimer , a physicist who taught at Caltech for part of each year.
They were frequently seen about town in his Chrysler coupe. At Christmas time she went up to Berkeley without her husband, to spend time with Robert.
His friend Haakon Chevalier met Kitty at a holiday dinner party thrown by the pianist Estelle Caen, one of Robert's ex-girlfriends.
Harrison declined, as he was engaged in his research, but Kitty accepted. Kitty impressed them with her riding ability; horsemanship was a normal accomplishment for women of her social class, and she had learned to ride as a girl on the riding trails around Aspinwall.
The following day Page rode to Perro Caliente on her bay horse to return Kitty's night gown, which had been left under Robert's pillow.
Kitty later told Anne Wilson that she got Robert to marry her the "old-fashioned way"—by getting pregnant. Soon after, Robert shared a podium with Nelson to raise money for refugees from the Spanish Civil War, and he informed him that he was engaged to Kitty.
Nelson's wife was also pregnant, and he named his daughter, who was born in November , Josie in memory of Dallet.
To obtain a divorce, Kitty moved to Reno, Nevada , where she stayed for six weeks to meet the state's residency requirements.
The divorce was finalised on November 1, , and Kitty married Robert the following day in a civil ceremony in Virginia City, Nevada , with the court janitor and clerk as witnesses.
Their child, a son they called Peter, was born in Pasadena, on May 12, , during Robert's regular session at Caltech.
Kitty worked at the University of California as a laboratory assistant. They left Peter with the Chevaliers and a German nurse and headed out to Perro Caliente for the summer.
The holiday was marred when Robert was trampled by a horse, and Kitty was injured when she had an accident in their Cadillac convertible.
Among the first were the Serbers, who moved into the apartment over the garage at One Eagle Hill. By the end of the month, they had moved to Los Alamos, New Mexico , where they occupied one of the buildings formerly belonging to the Los Alamos Ranch School.
Robert became the director of Project Y. Hempelmann, conducting blood tests to assess the danger of radiation.
Gray gibt dem Einspruch statt. Morgan entgegnet, dass die kommenden Generationen der Wissenschaftler sich an diese Verhältnisse angepasst haben.
Er stand den kommunistischen Organisationen nahe, war jedoch kein Mitglied der kommunistischen Partei und wollte dieser auch nicht beitreten, da er sich in seiner Unabhängigkeit nicht beeinflussen lassen wollte.
Er sah die Welt durch den Faschismus bedroht und den Kommunismus als eine Alternative an, die aktiv dagegen vorging.
Ich hatte Verwandte in Deutschland, Juden, denen ich helfen konnte, in dieses Land zu kommen, und sie erzählten mir, was damals dort geschah.
Robb verdächtigt Oppenheimer, dass am Juli in dessen Haus in Berkeley ein geschlossenes Treffen kommunistischer Funktionäre stattgefunden hat.
Ein Zeuge namens Paul Crouch und dessen Frau sollen das bezeugt haben. Marks beantragt, dass die Zeugen erscheinen und ihre Aussage bezeugen sollen.
Marks kann dann jedoch belegen, dass sich Dr. Oppenheimer lehnt die Verwendung eines Telexentwurfs von Marks, einen zur damaligen Zeit verwendeten Fernschreibertext, ab.
Marks will die Verhandlung an die Öffentlichkeit bringen, um die defensive Verteidigung Oppenheimers offensiver zu gestalten. Die Anwälte wollen den Fall der Öffentlichkeit zugänglich machen.
Oppenheimer will jedoch nicht, dass die Anwälte so vorgehen, sondern dass sie weiter auf seine Verteidigung setzen.
Garrison und Marks sehen in der Verhandlung ein Exempel, um die Wissenschaft zu unterdrücken. Die Verteidigung hat keinen Zugriff auf die Verhandlungsgegenstände.
Es geht um Sie als politisches Exempel. Doch Oppenheimer geht es nicht darum, sondern nur um seine Sicherheitsgarantie. Doch da Oppenheimers Arbeitsvertrag sowieso nur noch 3 Monate läuft, wäre dieses Verfahren ohne einen politischen Hintergrund nicht notwendig.
Am Verhör des 5. Tages wird Oppenheimer über seine Auswahlkriterien für die an dem Atomwaffenprojekt beteiligten Wissenschaftler befragt.
Er sagt, dass er es zwar damals für möglich hielt, einen Kommunisten an dem Projekt einzusetzen, heute allerdings nicht mehr.
Nach dem Zweiten Weltkrieg war das jedoch nicht mehr denkbar, da sich im kalten Krieg Russland als möglicher Gegner Amerikas herausstellte.
Die Kommunistische Partei der USA wurde als Spionageinstrument verwendet, was Oppenheimer jedoch nicht bekannt war, da sie eine legale Partei war und Amerika im Kampf gegen Hitlerdeutschland unterstützt hatte.
Oppenheimer schlug keine Mitglieder der kommunistischen Partei vor, da er sich nicht sicher sein konnte, dass diese sich loyal gegenüber den Vereinigten Staaten verhielten.
Er sah die Gefahr der Indiskretion. Bei ehemaligen Mitgliedern der Partei sah er jedoch nicht zwingend diese Gefahr. Robb will nun von Oppenheimer wissen, wie er die Loyalität überprüfte.
Oppenheimer hielt jedoch einen solchen Vertrauenstest bei seinem Bruder nicht notwendig, da er ihn für vertrauenswürdig erachtete.
Er ist der Ansicht, dass es zwar allgemein sinnvoll ist, Kommunisten nicht an den Projekten zu beteiligen, dass es in Ausnahmefällen aber auch solche gibt, die sich als loyal erweisen.
Evans will von Oppenheimer wissen, ob er Fuchs näher kannte. Dieser gibt an, dass er ihn nur flüchtig kannte und ihn für sehr introvertiert hielt.
Die Russen bekamen aber durch die Informationen von May und Fuchs keine wesentlichen Informationen für den Bau ihrer Atombombe, da ihre Konzepte anders aufgebaut waren.
Die Befragung wird nun wieder auf Oppenheimers Bruder gerichtet. Dieser trat zwischen und in die Partei ein und aus.
Er wurde erst an nichtgeheimen Projekten in Stanford eingesetzt, ging jedoch später nach Berkley, wo er an geheimen Strahlungsprojekten arbeitete.
Oppenheimer teilte den Sicherheitsbehörden nicht mit, dass sein Bruder Mitglied der Kommunistischen Partei war. Ich missbillige, dass ein Mensch wegen seiner gegenwärtigen oder vergangenen Ansichten vernichtet wird.
Das missbillige ich. Rolander verwendet sein Diktiergerät. Sie sind praktisch. Wo sie Ideologie haben ist bei mir nur ein blinder Fleck.
Rolander befragt Oppenheimer am 7. Verhörtag über politischen Sympathisanten zur Zeit des Manhattan-Projekts.
Er will die Ursachen erfahren, weshalb so viele Physiker in Los Alamos mit dem Kommunismus sympathisieren.
Sie experimentieren gern und ihre Gedanken sind auf Veränderung gerichtet. Bei ihrer Arbeit, und so auch in politischen Fragen.
Oppenheimer setzte diese im Manhattan-Projekt ein, da er sie für fachlich kompetent hielt. Als Rolander fragt, weshalb Oppenheimer so viele kommunistische Beziehungen hatte, antwortet dieser:.
Das scheint mir unweise, und es ist unzulässig, sie dieser Ansicht wegen herabzusetzen und verfolgen zu wollen. Nachdem dies herauskam, empfahl Oppenheimer ihnen einen Anwalt und nahm auch an ihrer Abschiedsparty teil.
Er gibt an, dass er wegen der hohen Arbeitslosigkeit, die auch seine Studenten betraf, den marxistischen Ideen nahestand, worin er zumindest zeitweise eine Alternative sah.
Morgan und Gray rauchen Zigarren. Die subjektive Meinung der Wissenschaftler spielt für ihn keine Rolle, solange sie ihre objektive Arbeit nicht beeinflusst.
Es solle geklärt werden, ob Oppenheimer sich hieran gehalten hat. Gray stimmt ihm zu. Verhörtag, dem April , ist der Geburtstag Robert Oppenheimers.
Robb gratuliert ihm. Er fragt ihn, ob Haakon Chevalier ihm eine Geburtstagskarte geschickt hat. Oppenheimer bejaht das. Chevalier ist ein französischer Schriftsteller, welcher linke Ansichten vertritt.
Er ist ein Freund Oppenheimers. Und Chevalier sagte, dass er völlig mit mir übereinstimme. Er gab an, dass er von Eltentons Absichten durch 3 Mittelsmänner erfahren hätte.
Er wollte Chevalier nicht nennen, um ihn zu schützen und ihn nicht mit der Sache in Verbindung zu bringen. Erst als ihm General Groves den militärischen Befehl gab, die Namen zu nennen, nannte er sich und Chevalier.
Der von Robb geladene Colonel Pash belastet Oppenheimer. Er ist der Überzeugung, dass die Aussage, die Oppenheimer zuerst machte, die Wahrheit war und Oppenheimer ein Sicherheitsrisiko darstellt.
Hier erzählt Oppenheimer die nach seinen Angaben erfundene Version der Geschehnisse. Er war dafür verantwortlich, Oppenheimer die Sicherheitsgarantie zu erteilen oder sie ihm zu verweigern.
Oppenheimer galt damals als der Einzige, der Los Alamos verwirklichen konnte. Das FBI war ihm gegenüber jedoch skeptisch.
Lansdale war davon überzeugt, dass Oppenheimer kein Kommunist war und dass er seinen Bruder schützen wollte und nicht Chevalier.
Er gibt an, dass das Verhalten Oppenheimers typisch für die Wissenschaftler war. Rolander fragt ihn, was er mit den Aufnahmen des Gesprächs zwischen Oppenheimer und Jean Tatlock gemacht hat.
Er sagt, dass er die Aufnahmen vernichtet habe. Als Rolander den Inhalt des Gespräches erfahren will, gibt Lansdale keine Auskunft, da er dieses Gespräch für zu privat hielt.
Gray bestätigt, dass er dazu aufgrund des früheren Antrags keine Aussagen machen muss. Lansdale sieht das Verfahren als hysterisch an und kritisiert, dass Dinge, die in der Vergangenheit stattfanden, mit den aktuellen Gefühlen beurteilt würden.
Evans befragte die beiden Zeugen nach der Sicherheit in Atomwaffenprojekten. Pash ist der Ansicht, dass zur Bewahrung der Sicherheit die Freiheit eingeschränkt werden müsse.
Dort riet er von der Wasserstoffbombe ab. Dies bedeutete seinen Ausschluss aus geheimen Regierungsprojekten und damit auch eine massive Reduzierung seiner politischen Einflussnahme.
Besonders Edward Teller bekam die Folgen seiner zwar recht neutral formulierten, für Oppenheimer aber letztendlich fatalen Aussage vor dem Ausschuss [17] zu spüren und wurde von seinen ehemaligen Kollegen teilweise wie ein Paria , d.

Im Anschluss gab er das unter Rutherford verlangte experimentelle Arbeiten auf und konzentrierte sich auf die theoretische Physik, die seinem einzigartigen Talent deutlich besser entsprach.
Bereits im Jahr hatte Robert Oppenheimer mehrere Abhandlungen über die Quantenmechanik und die Atomstrukturen veröffentlicht und damit das Interesse des deutschen Physikers und späteren Nobelpreisträgers Max Born geweckt.
Dieser holte Robert Oppenheimer nach Göttingen, wo der junge Wissenschaftler im Jahr promovierte und in engem Kontakt mit einigen der führenden europäischen Atomwissenschaftler wie Niels Bohr , Paul Dirac und Werner Heisenberg stand.
Während seiner Zeit in Göttingen veröffentlichte Oppenheimer zahlreiche Arbeiten über Quanten- und Atomphysik, die ihm im Alter von nur 25 Jahren eine Anstellung als Assistenzprofessor an der University of California in Berkeley ermöglichten.
Im Zuge seiner Tätigkeit für diese Operation gelang es Oppenheimer, einige der führenden Wissenschaftler jener Zeit für das Projekt zu gewinnen.
Die Anzahl jener Menschen der nachfolgenden Generationen, die als Bewohner dieser japanischen Städte später aufgrund der radioaktiven Verseuchung erkrankten und starben, kann bis heute nicht verifiziert werden.
Oppenheimer versuchte, die Entwicklung der Wasserstoffbombe zu verhindern, indem er die wissenschaftlichen Arbeiten behinderte.
Seine Einstellung gegen die Wasserstoffbombe resultierte aus den Verwüstungen in Japan, die Oppenheimer zutiefst schockiert hatten.
Er wurde in der McCarthy-Ära von einem Ausschuss beschuldigt, in kommunistischen Kreisen zu verkehren, da das FBI seine Vergangenheit durchleuchtet und dabei Kontakte des Wissenschaftlers zu politisch linksgerichteten Intellektuellen aufgedeckt hatte.
Erst neun Jahre später wurde er durch John F. Kennedy rehabilitiert und auf dessen Wunsch mit dem Enrico-Fermi-Preis der Atomenergiebehörde ausgezeichnet.
Die letzten Lebensjahre verbrachte Robert Oppenheimer damit, Arbeiten über die Beziehung zwischen Gesellschaft und Wissenschaft zu veröffentlichen.
Er erlag am Tatlock broke up with Oppenheimer in , after a tempestuous relationship. Kitty had been married before.
Her first marriage lasted only a few months. Her second, common-law marriage husband was Joe Dallet, an active member of the Communist party, who was killed in the Spanish Civil War.
There she married Richard Harrison, a physician and medical researcher, in In June Kitty and Harrison moved to Pasadena, California , where he became chief of radiology at a local hospital and she enrolled as a graduate student at the University of California, Los Angeles.
Oppenheimer and Kitty created a minor scandal by sleeping together after one of Tolman's parties. In the summer of she stayed with Oppenheimer at his ranch in New Mexico.
She finally asked Harrison for a divorce when she found out she was pregnant. When he refused, she obtained an instant divorce in Reno, Nevada , and took Oppenheimer as her fourth husband on November 1, When he joined the Manhattan Project in , Oppenheimer wrote on his personal security questionnaire that he had been "a member of just about every Communist Front organization on the West Coast".
It recorded that he attended a meeting in December at Chevalier's home that was also attended by the Communist Party's California state secretary William Schneiderman , and its treasurer Isaac Folkoff.
At his security clearance hearings, he denied being a member of the Communist Party, but identified himself as a fellow traveler , which he defined as someone who agrees with many of the goals of Communism, but without being willing to blindly follow orders from any Communist party apparatus.
Throughout the development of the atomic bomb, Oppenheimer was under investigation by both the FBI and the Manhattan Project's internal security arm for his past left-wing associations.
He was followed by Army security agents during a trip to California in June to visit his former girlfriend, Jean Tatlock, who was suffering from depression.
Oppenheimer spent the night in her apartment. When pressed on the issue in later interviews, Oppenheimer admitted that the only person who had approached him was his friend Haakon Chevalier, a Berkeley professor of French literature, who had mentioned the matter privately at a dinner at Oppenheimer's house.
Groves, Jr. On July 20, , he wrote to the Manhattan Engineer District:. In accordance with my verbal directions of July 15, it is desired that clearance be issued to Julius Robert Oppenheimer without delay irrespective of the information which you have concerning Mr Oppenheimer.
He is absolutely essential to the project. Roosevelt approved a crash program to develop an atomic bomb. Conant , who had been one of Oppenheimer's lecturers at Harvard, invited Oppenheimer to take over work on fast neutron calculations, a task that Oppenheimer threw himself into with full vigor.
He was given the title "Coordinator of Rapid Rupture", which specifically referred to the propagation of a fast neutron chain reaction in an atomic bomb.
One of his first acts was to host a summer school for bomb theory at his building in Berkeley. The mix of European physicists and his own students—a group including Robert Serber, Emil Konopinski , Felix Bloch , Hans Bethe and Edward Teller —kept themselves busy by calculating what needed to be done, and in what order, to make the bomb.
In June , the US Army established the Manhattan Project to handle its part in the atom bomb project and began the process of transferring responsibility from the Office of Scientific Research and Development to the military.
This was a choice that surprised many because Oppenheimer had left-wing political views and no record as a leader of large projects.
Groves was concerned by the fact that Oppenheimer did not have a Nobel Prize and might not have had the prestige to direct fellow scientists. As a military engineer , Groves knew that this would be vital in an interdisciplinary project that would involve not just physics, but chemistry, metallurgy , ordnance and engineering.
Groves also detected in Oppenheimer something that many others did not, an "overweening ambition" that Groves reckoned would supply the drive necessary to push the project to a successful conclusion.
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".
Oppenheimer and Groves decided that for security and cohesion they needed a centralized, secret research laboratory in a remote location. Scouting for a site in late , Oppenheimer was drawn to New Mexico, not far from his ranch.
On November 16, , Oppenheimer, Groves and others toured a prospective site. Oppenheimer feared that the high cliffs surrounding the site would make his people feel claustrophobic , while the engineers were concerned with the possibility of flooding.
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 called the Los Alamos Ranch School.
The engineers were concerned about the poor access road and the water supply, but otherwise felt that it was ideal. At the laboratory, Oppenheimer assembled a group of the top physicists of the time, which he referred to as the "luminaries".
Los Alamos was initially supposed to be a military laboratory, and Oppenheimer and other researchers were to be commissioned into the Army.
He went so far as to order himself a lieutenant colonel's uniform and take the Army physical test, which he failed.
Conant, Groves, and Oppenheimer devised a compromise whereby the laboratory was operated by the University of California under contract to the War Department.
Oppenheimer at first had difficulty with the organizational division of large groups, but rapidly learned the art of large-scale administration after he took up permanent residence on the mesa.
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.
He was an iconic figure to his fellow scientists, as much a symbol of what they were working toward as a scientific director. Victor Weisskopf put it thus:.
Oppenheimer directed these studies, theoretical and experimental, in the real sense of the words. 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 did not direct from the head office. He was intellectually and physically present at each decisive step. He was present in the laboratory or in the seminar rooms, when a new effect was measured, when a new idea was conceived.
It was not that he contributed so many ideas or suggestions; he did so sometimes, but his main influence came from something else.
It was his continuous and intense presence, which produced a sense of direct participation in all of us; it created that unique atmosphere of enthusiasm and challenge that pervaded the place throughout its time.
In development efforts were directed to a plutonium gun-type fission weapon called " Thin Man ". Initial research on the properties of plutonium was done using cyclotron -generated plutonium , which was extremely pure but could only be created in tiny amounts.
When Los Alamos received the first sample of plutonium from the X Graphite Reactor in April a problem was discovered: reactor-bred plutonium had a higher concentration of plutonium , making it unsuitable for use in a gun-type weapon.
Using chemical explosive lenses , a sub-critical sphere of fissile material could be squeezed into a smaller and denser form.
The metal needed to travel only very short distances, so the critical mass would be assembled in much less time. In May an Interim Committee was created to advise and report on wartime and postwar policies regarding the use of nuclear energy.
The Interim Committee in turn established a scientific panel consisting of Arthur Compton , Fermi, Lawrence and Oppenheimer to advise it on scientific issues.
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.
The joint work of the scientists at Los Alamos resulted in the world's first nuclear explosion , near Alamogordo, New Mexico on July 16, Oppenheimer had given the site the codename " Trinity " in mid and said later that it was from one of John Donne 's Holy Sonnets.
According to the historian Gregg Herken, this naming could have been an allusion to Jean Tatlock, who had committed suicide a few months previously and had in the s introduced Oppenheimer to Donne's work.
If the radiance of a thousand suns were to burst at once into the sky, that would be like the splendor of the mighty one We knew the world would not be the same.
A few people laughed, a few people cried. Most people were silent. 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.
Brigadier General Thomas Farrell , who was present in the control bunker at the site with Oppenheimer, summarized his reaction as follows:. Oppenheimer, on whom had rested a very heavy burden, grew tenser as the last seconds ticked off.
He scarcely breathed. He held on to a post to steady himself. For the last few seconds, he stared directly ahead and then when the announcer shouted "Now!
Physicist Isidor Rabi noticed Oppenheimer's disconcerting triumphalism: "I'll never forget his walk; I'll never forget the way he stepped out of the car He had done it.
He noted his regret the weapon had not been available in time to use against Nazi Germany. Stimson expressing his revulsion and his wish to see nuclear weapons banned.
The meeting, however, went badly, after Oppenheimer remarked he felt he had "blood on my hands". The remark infuriated Truman and put an end to the meeting.
Truman later told his Undersecretary of State Dean Acheson "I don't want to see that son-of-a-bitch in this office ever again.
The Manhattan Project was top secret and did not become public knowledge until after the bombings of Hiroshima and Nagasaki, and Oppenheimer became a national spokesman for science who was emblematic of a new type of technocratic power.
Like many scientists of his generation, he felt that security from atomic bombs would come only from a transnational organization such as the newly formed United Nations , which could institute a program to stifle a nuclear arms race.
In November , Oppenheimer left Los Alamos to return to Caltech, [] but he soon found that his heart was no longer in teaching.
This meant moving back east and leaving Ruth Tolman, the wife of his friend Richard Tolman, with whom he had begun an affair after leaving Los Alamos.
Oppenheimer brought together intellectuals at the height of their powers and from a variety of disciplines to answer the most pertinent questions of the age.
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.
He also instituted temporary memberships for scholars from the humanities, such as T. Eliot and George F. Some of these activities were resented by a few members of the mathematics faculty, who wanted the institute to stay a bastion of pure scientific research.
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.
During a series of conferences in New York from through , physicists switched back from war work to theoretical issues.
Under Oppenheimer's direction, physicists tackled the greatest outstanding problem of the pre-war years: infinite, divergent, and non-sensical expressions in the quantum electrodynamics of elementary particles.
Julian Schwinger , Richard Feynman and Shin'ichiro Tomonaga tackled the problem of regularization , and developed techniques which became known as renormalization.
Freeman Dyson was able to prove that their procedures gave similar results. The problem of meson absorption and Hideki Yukawa 's theory of mesons as the carrier particles of the strong nuclear force were also tackled.
Probing questions from Oppenheimer prompted Robert Marshak 's innovative two- meson hypothesis : that there were actually two types of mesons, pions and muons.
This led to Cecil Frank Powell 's breakthrough and subsequent Nobel Prize for the discovery of the pion. As a member of the Board of Consultants to a committee appointed by Truman, Oppenheimer strongly influenced the Acheson—Lilienthal Report.
In this report, the committee advocated creation of an international Atomic Development Authority, which would own all fissionable material and the means of its production, such as mines and laboratories, and atomic power plants where it could be used for peaceful energy production.
Bernard Baruch was appointed to translate this report into a proposal to the United Nations, resulting in the Baruch Plan of The Baruch Plan introduced many additional provisions regarding enforcement, in particular requiring inspection of the Soviet Union's uranium resources.
The Baruch Plan was seen as an attempt to maintain the United States' nuclear monopoly and was rejected by the Soviets. With this, it became clear to Oppenheimer that an arms race was unavoidable, due to the mutual suspicion of the United States and the Soviet Union, [] which even Oppenheimer was starting to distrust.
From this position he advised on a number of nuclear-related issues, including project funding, laboratory construction and even international policy—though the GAC's advice was not always heeded.
The first atomic bomb test by the Soviet Union in August came earlier than expected by Americans, and over the next several months there was an intense debate within the U.
A majority of the AEC subsequently endorsed the GAC recommendation — and Oppenheimer thought that the fight against the Super would triumph — but proponents of the weapon lobbied the White House vigorously.
In , Edward Teller and mathematician Stanislaw Ulam developed what became known as the Teller-Ulam design for a hydrogen bomb.
The program we had in was a tortured thing that you could well argue did not make a great deal of technical sense. It was therefore possible to argue also that you did not want it even if you could have it.
The program in was technically so sweet that you could not argue about that. 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 played a role on a number of government panels and study projects during the late s and early s, some of which found him in the middle of controversies and power struggles.
In Oppenheimer chaired the Department of Defense's Long-Range Objectives Panel, which looked at the military utility of nuclear weapons including how they might be delivered.
Oppenheimer participated in Project Charles during , which examined the possibility of creating an effective air defense of the United States against atomic attack, and in the follow-on Project East River in , which, with Oppenheimer's input, recommended building a warning system that would provide one-hour notice to atomic attacks against American cities.
Edward Teller, who had been so uninterested in work on the atomic bomb at Los Alamos during the war that Oppenheimer had given him time instead to work on his own project of the hydrogen bomb, [] had eventually left Los Alamos in to help found, in , a second laboratory at what would become the Lawrence Livermore National Laboratory.
Project Vista looked at improving U. Air Force, whereas the Vista conclusions recommended an increased role for the U. Army and U. Navy as well. During Oppenheimer chaired the five-member State Department Panel of Consultants on Disarmament , [] which first urged that the United States postpone its planned first test of the hydrogen bomb and seek a thermonuclear test ban with the Soviet Union, on the grounds that avoiding a test might forestall development of a catastrophic new weapon and open the way for new arms agreements between the two nations.
Thus by , 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.
The FBI under J. Edgar Hoover had been following Oppenheimer since before the war, when he showed Communist sympathies as a professor at Berkeley and had been close to members of the Communist Party, including his wife and brother.
He had been under close surveillance since the early s, his home and office bugged, his phone tapped and his mail opened. 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".
On June 7, , Oppenheimer testified before the House Un-American Activities Committee , where he admitted that he had associations with the Communist Party in the s.
Frank was subsequently fired from his University of Minnesota position. Unable to find work in physics for many years, he became instead a cattle rancher in Colorado.
He later taught high school physics and was the founder of the San Francisco Exploratorium. The triggering event for the security hearing happened on November 7, , [] 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 a letter to Hoover which said that "more probably than not J.
Robert Oppenheimer is an agent of the Soviet Union. One of the key elements in this hearing was Oppenheimer's earliest testimony about George Eltenton's approach to various Los Alamos scientists, a story that Oppenheimer confessed he had fabricated to protect his friend Haakon Chevalier.
Unknown to Oppenheimer, both versions were recorded during his interrogations of a decade before. He was surprised on the witness stand with transcripts of these, which he had not been given a chance to review.
In fact, Oppenheimer had never told Chevalier that he had finally named him, and the testimony had cost Chevalier his job. Both Chevalier and Eltenton confirmed mentioning that they had a way to get information to the Soviets, Eltenton admitting he said this to Chevalier and Chevalier admitting he mentioned it to Oppenheimer, but both put the matter in terms of gossip and denied any thought or suggestion of treason or thoughts of espionage, either in planning or in deed.
Neither was ever convicted of any crime. In a great number of cases, I have seen Dr. Oppenheimer act—I understand that Dr. Oppenheimer acted—in a way which was for me was exceedingly hard to understand.
I thoroughly disagreed with him in numerous issues and his actions frankly appeared to me confused and complicated. 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 this very limited sense I would like to express a feeling that I would feel personally more secure if public matters would rest in other hands.
This led to outrage by the scientific community and Teller's virtual expulsion from academic science. Inconsistencies in his testimony and his erratic behavior on the stand, at one point saying he had given a "cock and bull story" and that this was because he "was an idiot", convinced some that he was unstable, unreliable and a possible security risk.
Oppenheimer's clearance was revoked one day before it was due to lapse anyway. During his hearing, Oppenheimer testified willingly on the left-wing behavior of many of his scientific colleagues.
Had Oppenheimer's clearance not been stripped then he might have been remembered as someone who had "named names" to save his own reputation.
Soviet intelligence tried repeatedly to recruit him, but was never successful; Oppenheimer did not betray the United States. In addition, he had several persons removed from the Manhattan Project who had sympathies to the Soviet Union.
Moreover, in terms of the time, effort and money spent on Party activities, he was a very committed supporter".
Starting in , Oppenheimer lived for several months of the year on the island of Saint John in the U. Virgin Islands. In , he purchased a 2-acre 0. Oppenheimer was increasingly concerned about the potential danger that scientific inventions could pose to humanity.
He joined with Albert Einstein , Bertrand Russell , Joseph Rotblat and other eminent scientists and academics to establish what would eventually, in , become the World Academy of Art and Science.
Significantly, after his public humiliation, he did not sign the major open protests against nuclear weapons of the s, including the Russell—Einstein Manifesto of , nor, though invited, did he attend the first Pugwash Conferences on Science and World Affairs in 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.
Oppenheimer rejected the idea of nuclear gunboat diplomacy. In the philosophy and psychology departments at Harvard invited Oppenheimer to deliver the William James Lectures.
An influential group of Harvard alumni led by Edwin Ginn that included Archibald Roosevelt protested against the decision. Deprived of political power, Oppenheimer continued to lecture, write and work on physics.
He toured Europe and Japan, giving talks about the history of science, the role of science in society, and the nature of the universe. Kennedy awarded Oppenheimer the Enrico Fermi Award in as a gesture of political rehabilitation.
Edward Teller, the winner of the previous year's award, had also recommended Oppenheimer receive it, in the hope that it would heal the rift between them.
President, that it has taken some charity and some courage for you to make this award today. The late President Kennedy's widow Jacqueline , still living in the White House, made it a point to meet with Oppenheimer to tell him how much her husband had wanted him to have the medal.
This was partly due to lobbying by the scientific community on behalf of Oppenheimer. Oppenheimer was a chain smoker who was diagnosed with throat cancer in late After inconclusive surgery, he underwent unsuccessful radiation treatment and chemotherapy late in A memorial service was held a week later at Alexander Hall on the campus of Princeton University.
The service was attended by of his scientific, political and military associates that included Bethe, Groves, Kennan, Lilienthal, Rabi, Smyth and Wigner.
His brother Frank and the rest of his family were also there, as was the historian Arthur M. Schlesinger, Jr. Bethe, Kennan and Smyth gave brief eulogies.
His wife Kitty took the ashes to St. John and dropped the urn into the sea, within sight of the beach house. In October , Kitty died at age 62 from an intestinal infection that was complicated by a pulmonary embolism.
