For his scientific achievement, he would be forever known as the father of the atomic bomb—but never as a Nobel laureate.

The pinnacle of global recognition, the Nobel Prize was awarded to 18 of J. Robert Oppenheimer’s colleagues with whom he worked at the Manhattan Project site in Los Alamos. There, in just 27 months and in a perceived race with Nazi Germany, the scientists created the first nuclear weapons. Their efforts brought the world into the Atomic Age and helped end World War II. Several earned the prize before coming to work at the wartime lab, while most would go on to win later in life. Oppenheimer was nominated for the Nobel Prize in Physics three times: in 1946, 1951, and 1967. Colleagues, scholars, and surely Oppenheimer himself pondered why he was never bestowed the honor. “To understand this,” said James Kunetka, historian and author of The General and the Genius, “you have to first examine the man’s academic life before and after the war.”
Undisputed genius
Born in 1904 into a wealthy Jewish family and raised in New York, Oppenheimer was obviously gifted. He completed the third and fourth grade in just one year and later skipped a portion of his eighth-grade year. Remarkable anecdotes of brilliance illustrate his life through early adulthood. As a boy, he was interested in mineralogy and, at age 12, presented his research paper to the New York Mineralogical Club and became an honorary member. As a young academic, he learned Dutch in six weeks to successfully deliver a technical lecture on a trip to the Netherlands. It was there he was first dubbed “Oppie” (“Opje” in Dutch).
“[He was] one of the sharpest people I have ever seen or heard of, intellectually,” said longtime friend Harold Cherniss in a 1979 interview. “When he became interested in anything, he very quickly picked up an enormous amount of knowledge about it.”
After graduating at the top of his high school class, Oppenheimer studied science at Harvard University, where he was admitted to graduate-level physics classes during his first year. He also took courses in languages, literature, philosophy, and religion, earning his degree in just three years, but with no social clubs or athletics listed under his name in the 1926 yearbook. Introverted, and perhaps lonely, Oppenheimer once told a friend, “It’s no fun to turn the pages of a book and say, ‘Yes, yes, of course, I know that,’” according to an October 1949 article in Life magazine.
After a stint at the University of Cambridge in the United Kingdom, Oppenheimer went to the University of Göttingen in Germany, where he studied quantum physics and earned his doctorate in 1927. By 1929, he accepted offers to teach at both the California Institute of Technology (Caltech) and the University of California, Berkeley.
Oppenheimer’s early research focused on energy processes of subatomic particles, including electrons, positrons, cosmic rays, neutron stars, and black holes. He was soon recognized as a leader in theoretical physics and had earned the respect of scientific greats such as Albert Einstein and Niels Bohr.
“However, many of his colleagues and critics point out that his production of significant papers was surprisingly thin,” Kunetka said. “It was said by some that he far too often co-authored papers with his students rather than initiated them. [Nobel laureate and physicist] Hans Bethe noted that, while Oppenheimer and others were perhaps more brilliant, he [Bethe] was more productive.”
Oppenheimer was an outstanding teacher, inspiring and influencing students. He earned a loyal following, if not outright adoration. “Like most of his students, I would more or less follow him to the ends of the earth,” recalled Manhattan Project scientist Robert Christy in a 1983 interview.
Leadership
Oppenheimer lacked large-scale managerial experience prior to his directorship at Los Alamos, and his associations with members of the Communist Party, including friends, a former girlfriend, and his brother, were problematic. And without a Nobel Prize, it wasn’t certain whether Oppenheimer would have the prestige to lead the Los Alamos scientists.
But as soon as General Leslie Groves met Oppenheimer, none of that mattered, according to Oppenheimer biographer Ray Monk. The young professor impressed the Manhattan Project leader with both his intelligence and practicality. Oppenheimer would seemingly be able to turn blackboard theories and lab experiments into atomic weapons. Groves also may have seen a drive-based ambition, according to Monk, assuring him that Oppenheimer would, indeed, succeed.
In the fall of 1942, Groves hired the 38-year-old Oppenheimer to direct the wartime laboratory. Oppenheimer recommended Los Alamos as the site for the clandestine lab and recruited science’s greatest minds to join him there. By then, Oppenheimer was described as charismatic and charming. He was the center of attention at parties, drinking his signature martinis and gesticulating with cigarettes through story after story. “Oppenheimer commanded not just the loyalty but the deep respect of everybody who was at Los Alamos, and I cannot think of anyone else who would have succeeded as he did in that sense,” said Manhattan Project physicist and Nobel laureate Roy Glauber.
But Oppenheimer also was known as cruel and intolerant toward those he perceived as intellectually inferior, and was called a showman and a power seeker. Nevertheless, according to Alan Carr, senior historian at Los Alamos National Laboratory’s National Security Research Center, Oppenheimer’s worst enemies would concede that he achieved greatness during the war.
“He was very close to being indispensable,” an unnamed Los Alamos scientist said, according to the 1949 Life article. Another said, “The main decisions were made by Oppenheimer, and all proved to be correct.”
Atomic success
Oppenheimer’s directorship, perhaps along with his genius, culminated on July 16, 1945, when the world’s first-ever atomic device was successfully detonated in the New Mexico desert. Oppenheimer, who read and wrote poetry, named the test “Trinity.” He said years afterward that he may have been inspired by a John Donne poem that includes the line: “Batter my heart, three-person’d God.”
Weeks later and just days apart, the United States released the gun-type uranium bomb, Little Boy, and the implosion-style plutonium bomb, Fat Man, above Japan.
Groves phoned Oppenheimer after the first detonation.
According to a transcript of the recorded call, Groves said, “I think one of the wisest things I ever did was when I selected [you] the director of Los Alamos.”
To which Oppenheimer responded: “Well, I have my doubts, General Groves.”
And Groves replied: “Well, you know I’ve never concurred with those doubts at any time.”
After World War II
Oppenheimer once said “physics and desert country” were his “two great loves.” In Los Alamos these came together, and it’s where his work as a physicist changed the world.
He left Los Alamos a few weeks after World War II's official end on September 2, 1945. “Oppenheimer” was now a household name. With his face on magazine covers, star treatment followed. His celebrity, though, did not translate into a Nobel Prize.
He first returned to Caltech but soon left to lead the Institute for Advanced Study in Princeton, New Jersey, and serve as the chairman of the General Advisory Committee, a scientific panel that advised the newly formed Atomic Energy Commission. Much of his focus shifted from his pre-war physics work to policy work. Oppenheimer spoke out in opposition to the development of the even more powerful hydrogen bomb, questioning its feasibility and deeming it an unnecessary weapon. Meanwhile, he wrote and lectured but did not resume much research.
In 1954, he lost his security clearance following unsubstantiated accusations against his loyalty. Though his supporters remained steadfast and numerous, Oppenheimer eventually retreated from public life and work, pushing him further from a Nobel Prize than ever.
“Science is not everything,” Oppenheimer once said, “but science is very beautiful.”
Why no prize?
Kunetka says the simplest explanation is that before World War II, Oppenheimer’s published work was not considered significant enough. Carr agrees, adding that Oppenheimer never made a major discovery, nor did he ever prove a significant theory.
“The Nobel Prize requires more than just a remarkable idea,” Carr said, “it requires evidence.”
Of his Manhattan Project work, Oppenheimer himself said that creating the atomic bombs was inventive rather than scientific, according to the 1949 Life article.
When he was first nominated in 1946 for the Nobel Prize, the Nobel committee was hesitant to award it to someone so closely tied to the atomic bombs, according to American Prometheus. Many scholars and scientists through the years have concurred.
Others, though, have said Oppenheimer’s scientific focus changed frequently and he didn’t work sufficiently in any one area to warrant the Nobel Prize. Meanwhile, Monk thought Oppenheimer’s work was more significant than credited, and some scientists, including Nobel laureate Luis Alvarez, speculated that Oppenheimer’s work on black holes may have warranted the prize, had he lived long enough to see it brought to fruition. (Nobel Prizes are not awarded posthumously.)
“In the end,” Kunetka said, “we don’t know.”
Carr adds, “Did he achieve greatness? Yes, of course. What Oppie led his wartime team of scientists to achieve was nothing short of remarkable. He will always have that incredible scientific legacy.”
Loyal following until the end
Oppenheimer died at his New Jersey home on February 18, 1967, after unsuccessful treatments for throat cancer. He was 62 and was survived by his wife, Kitty, and their two children. Kitty spread his ashes near their simple beach home in the U.S. Virgin Islands, following a memorial service at Princeton University. An estimated 600 people attended.
