Robert Oppenheimer is referred to as the father of the atomic bomb for his work on the Manhattan Project. Oppenheimer’s life and contributions have been the subjects of numerous biographies, documentaries, and historical works. Read here to know the biography of the famous physicist.
Oppenheimer’s life has been extremely eventful and dramatic hence has been the subject of various adaptations in literature and the silver screen as well.
He is best known for his work in the Manhattan Project– a research and development undertaking of the US during World War II for developing the first nuclear weapons. The project had the support of other nations like the UK and Canada.
Oppenheimer was the director of the Los Almos Laboratory that designed the atomic bombs.
The early life of Robert Oppenheimer
Robert Julius Oppenheimer, born on April 22, 1904, and commonly known as Robert Oppenheimer, was an American theoretical physicist and one of the key figures in the development of the atomic bomb during World War II.
He is often referred to as the “father of the atomic bomb” for his significant contributions to the Manhattan Project.
Oppenheimer was born in New York City and showed exceptional academic abilities from a young age.
He attended Harvard University, where he completed his undergraduate studies before moving on to conduct his doctoral research in theoretical physics at the University of Göttingen in Germany in 1926.
- In the 1930s, Oppenheimer made important contributions to theoretical physics, particularly in the field of quantum mechanics and quantum field theory.
- He was also influential in promoting the use of quantum mechanics in astrophysics.
- By the late 1930s, he was a prominent professor at the University of California, Berkeley.
Oppenheimer and Manhattan Project
With the outbreak of World War II, Oppenheimer became deeply involved in the United States’ efforts to build an atomic bomb.
He was appointed as the scientific director of the Manhattan Project in 1942, overseeing the development of the first nuclear weapons.
The project’s success led to the first test of an atomic bomb on July 16, 1945, at the Trinity test site in New Mexico.
- His leadership and scientific expertise were instrumental in the project’s success. On July 16, 1945, he was present at the Trinity test of the first atomic bomb.
- In August 1945, the weapons (Little Boy and Fat Man) were used in the bombings of Hiroshima and Nagasaki in Japan, which remain the only use of nuclear weapons in an armed conflict.
Oppenheimer assumed leadership of the important General Advisory Committee of the recently established United States Atomic Energy Commission in 1947 while serving as the head of the Princeton, New Jersey-based Institute for Advanced Study.
To stop nuclear proliferation and a nuclear weapons race with the Soviet Union, he advocated for global nuclear power regulation.
During a 1949–1950 federal discussion on the subject, he was opposed to the creation of the hydrogen bomb.
Subsequently, he adopted stances on defense-related matters that infuriated several U.S. government and military groups.
After World War II, Oppenheimer faced scrutiny during the “Red Scare” era due to his left-leaning political affiliations and past associations with communists.
He was subjected to a security clearance hearing in 1954 and was eventually stripped of his security clearance.
This action effectively ended his government career and led to his exclusion from further nuclear research and policymaking.
Despite the controversies and setbacks, Oppenheimer continued to contribute to physics, teaching at the Institute for Advanced Study in Princeton, New Jersey.
He was a chain smoker and was diagnosed with throat cancer in 1965.
He remained a respected figure in the scientific community until his death on February 18, 1967.

Legacy of Robert Oppenheimer
Oppenheimer was a brilliant physicist, and his interests ranged from nuclear physics to quantum thermodynamics.
He has made significant contributions to various scientific theories like Oppenheimer-Phillips theory, Born-Oppenheimer approximation, and so on.
During the Trinity explosions, Oppenheimer mentioned that he was thinking of verses from the Bhagavat Gita, famously quoted by him “I become death, the destroyer of the worlds.”
After the bombings of Hiroshima and Nagasaki, the Manhattan Project’s top-secret nature came to light, and Oppenheimer rose to prominence as a national spokesperson for science and a symbol of a new kind of technocratic authority.
Robert Oppenheimer was more concerned about the threat that scientific advancements may bring to humanity.
- Along with other illustrious scholars and scientists, he founded what would ultimately become the World Academy of Art and Science in 1960. These individuals included Albert Einstein, Bertrand Russell, Joseph Rotblat, and others.
- Notably, following his public humiliation, he refused to sign the most important open protests against nuclear weapons in the 1950s, such as the Russell-Einstein Manifesto of 1955, and he also declined an invitation to the inaugural Pugwash Conferences on Science and World Affairs in 1957 despite being invited.
In September 1957, France made him an Officer of the Legion of Honor, and on May 3, 1962, he was elected a Foreign Member of the Royal Society in Britain.
President John F. Kennedy awarded Oppenheimer the Enrico Fermi Award in 1963 as a gesture of political rehabilitation.
President Lyndon Johnson, presented Oppenheimer with the award, “for contributions to theoretical physics as a teacher and originator of ideas, and leadership of the Los Alamos Laboratory and the atomic energy program during critical years”.
Robert Oppenheimer’s life and contributions have been the subjects of numerous biographies, documentaries, and historical works, highlighting both his brilliance as a physicist and the complex ethical questions surrounding the development and use of nuclear weapons.
