Robert Oppenheimer Biography

Julius Robert Oppenheimer (April 22, 1904 – February 18, 1967) was a physicist widely acknowledged as the father of atomic bomb. He was born in New York City, United States. Oppenheimer is renowned for his pivotal role in the development of the Manhattan Project during World War II, which culminated in the creation of the first atomic bombs.

 

Early years

Robert Oppenheimer was an American theoretical physicist, scientist, and university professor. He was the son of German-born Julius S. Oppenheimer and artist Ella Friedman. Coming from a wealthy and educated family in New York, his father was a Jewish owner of a significant fortune amassed through his textile factory. This allowed Oppenheimer to enjoy certain comforts and attend the best schools in the city.

In this regard, he was educated at the Ethical Culture School in New York, where he excelled as the top student, with some teachers even asserting that he was better than many of them. Upon graduating from school, he enrolled at Harvard University, where he stood out in all areas, from chemistry to Eastern philosophy, Greek, and Latin, completing his studies at the age of 21.

 

Career

After some time, Robert Oppenheimer decided to delve into the world of physics, capitalizing on both his aptitude for the subject and its burgeoning prominence across Europe. He moved to England, where he worked with Ernest Rutherford and J. J. Thomson. Alongside these two great scientists, he felt somewhat inadequate, as he believed his performance did not meet the required standards. However, Oppenheimer did not give up.

With the passage of time, he learned from his mentors, and by 1925, feeling more adapted, he began researching atomic energy and secondary-atomic particle energy processes at the Cavendish Laboratory.

A year later, he was at the University of Göttingen, collaborating with Max Born to develop his classical contribution to molecular quantum theory, known in physics as the “Born-Oppenheimer method”. He returned to his home country to teach theoretical physics at the California Institute of Technology and the University of Berkeley between 1929 and 1942. Oppenheimer was a highly political person. Therefore, in the 1930s, he decided to align himself with communist students to support the Republic during the Spanish Civil War, but certain actions led to the demise of his sympathy for the Communist Party.

 

Contribution to the Manhattan Project

The civil and political situation in Europe was becoming increasingly dangerous. By 1939, Albert Einstein and Leo Szilard warned the U.S. government about the dangers of nuclear energy falling into the hands of the Nazis. In response, President Franklin Roosevelt initiated the project for creating the atomic bomb, which was initially under military control, led by General Leslie Groves, an engineer known for overseeing construction projects, including the Pentagon. Later, Oppenheimer was brought on board to manage the administration of the project, which culminated in the construction of the atomic bomb by 1945.

Oppenheimer’s most significant contribution to the Manhattan Project was his leadership and effective coordination among diverse teams of scientists. His vision and problem-solving skills were crucial in overcoming the scientific and technological challenges involved in building an atomic bomb. He supervised the design and testing of the first atomic bombs, including the successful detonation of the plutonium bomb at the Trinity test site in New Mexico on July 16, 1945.

 

This American physicist had the support of many prominent figures in science, such as the great scientist Werner Heisenberg, Erwin Schrödinger, Max Born, Wolfgang Pauli, Paul Dirac, and Enrico Fermi, with whom he also developed close friendships. The work carried out by these scientists on quantum physics provided significant support for his own research. He gained valuable insights into quantum and relativistic physics, which kept him abreast of new scientific developments. He made contributions to the application of quantum theory to the concept of electron spin.

In his role as the director of the Institute for Advanced Study in Princeton, he fostered discussion and research in quantum and relativistic physics. In 1953, his past ties with the Communist Party led to certain defamation issues. As a result, he was called to a security hearing where the accusation was dismissed, but his access to military secrets was still prohibited. One of the institutions that attacked the scientist the most was the Federation of American Scientists. Oppenheimer was humiliated, and his communications were monitored. Nine years later, President John F. Kennedy, in an effort to rectify this mistake, awarded him the Enrico Fermi Award, granted by the Atomic Energy Commission, which he received from President Johnson himself.

 

“Now I Am Become Death, the Destroyer of Worlds”.

 

Oppenheimer, confessed to President Harry Truman, that he was not entirely comfortable with the fate of the atomic bomb. After some time, the Cold War erupted, and the Soviet Union announced its possession of an atomic weapon. In response, the United States decided to develop an even more powerful weapon. They approached Oppenheimer to lead the Atomic Energy Commission, but he declined the offer, resulting in his removal from the position. However, he remained the director at the Institute for Advanced Study, thanks to the support given by Einstein

, Von Neumann, and Bohr.

After this event, his life took a different turn as he decided to distance himself from the laboratories and leaned towards writing about the studies conducted throughout his scientific career. Notable works include “Science and the Common Understanding” (1954) and a book related to electrodynamics (published posthumously in 1970). In the aftermath of the events in Japan and the grave consequences the atomic bomb had on humanity, he made several proposals aimed at internationally regulating the use of atomic energy to ensure peace.

He staunchly opposed the creation of the hydrogen bomb. However, despite his efforts and those of the General Advisory Committee of the Atomic Energy Commission, its development continued. Disheartened, Oppenheimer made the decision to retire from Princeton in 1966. A year later, on February 18, 1967, he passed away from throat cancer.
