J. Robert Oppenheimer: The Father of the Atomic Bom

             

 Physicist J. Robert Oppenheimer played a pivotal role as the director of the Los Alamos Laboratory during the development of the atomic bomb. Following the 1939 Nazi invasion of Poland, Oppenheimer was chosen to oversee the Manhattan Project, a program aimed at creating the first nuclear weapon during World War II. After resigning in 1945, he assumed the role of chairman of the General Advisory Committee of the Atomic Energy Commission. President John F. Kennedy, prior to his 1963 assassination, announced Oppenheimer as the recipient of the Enrico Fermi Award for his contributions to physics, with President Lyndon B. Johnson presenting the award in December of that year. The "Father of the Atomic Bomb" passed away from cancer in 1967 at the age of 62.

 

Born on April 22, 1904, in New York City, J. Robert Oppenheimer was the son of German Jewish immigrants, Julius Oppenheimer, a wealthy textile importer, and Ella (née Friedman), a painter.

 

After completing his education at Harvard University, Oppenheimer traveled to England and enrolled at the University of Cambridge in 1925. Despite experiencing bouts of depression, he embarked on atomic research at the Cavendish Laboratory. Uninterested in laboratory work, Oppenheimer preferred theoretical physics over experimental work. Displeased with his Cambridge tutor, Patrick Blackett, Oppenheimer once left an apple doused with noxious chemicals on Blackett's desk, avoiding discipline with his parents' intervention.

 

Throughout his career, Oppenheimer held university professor positions, including collaborations with Max Born at Göttingen University in 1926. Here, he met renowned physicists such as Niels Bohr and contributed significantly to quantum molecular theory with the development of the Born-Oppenheimer approximation, earning his doctorate at Göttingen.

 

Active in politics during the 1930s, Oppenheimer, along with Albert Einstein and Leo Szilard, recognized the potential for Nazi Germany to develop nuclear weapons. Following the 1939 Nazi invasion of Poland, he was selected to lead the Manhattan Project. Despite reservations about his left-wing politics, lack of leadership experience, and absence of a Nobel Prize, Brigadier General Leslie R. Groves Jr. believed in Oppenheimer's "overweening ambition."

 

Beginning in 1942, Oppenheimer spearheaded the scientific aspect of the Manhattan Project in Los Alamos, New Mexico. The project aimed to explore the fission process involving uranium-235, with the goal of creating a nuclear bomb before Adolf Hitler could. The project, initially allocated $6,000 by the U.S. government, eventually saw its budget swell to $2 billion by its culmination in 1945.

In February 1946, Brigadier General K. D. Nichols and Professor H.D. Smythe attentively listen as J. Robert Oppenheimer elaborated on the atomic bomb.

Trinity Test and Reflections: Oppenheimer and his fellow scientists achieved the world's first nuclear explosion, code-named "Trinity," in New Mexico on July 16, 1945. Inspired by a John Donne poem, the detonation left a lasting impression on Oppenheimer, who reflected on verses from the Bhagavad Gita, including the famous quote, "I am become Death, the destroyer of worlds."

Initial Pleasure and Public Recognition: Initially pleased with the atomic bomb's success, Oppenheimer's elation was evident. Physicist Isidor Rabi noted his triumphant walk after the achievement. However, Oppenheimer's feelings changed after the bombings of Hiroshima and Nagasaki, particularly finding the latter unnecessary from a military perspective.

Opposition to Further Development: During a White House meeting with President Harry S. Truman, Oppenheimer expressed regret, claiming to have "blood on his hands." Despite the Hiroshima and Nagasaki bombings effectively ending World War II, Oppenheimer argued against further development of the devastating weapons and resigned from his post.

Father of the Atomic Bomb and Fallout: The Manhattan Project, initially top secret, became public knowledge post-Hiroshima and Nagasaki. Oppenheimer, despite returning to the California Institute of Technology, found little desire for teaching. His opposition to the development of the hydrogen bomb led to accusations of Communist sympathies, resulting in a security hearing in 1954, ending his government role.

Partial Rehabilitation and Legacy: In 1963, President John F. Kennedy announced Oppenheimer would receive the Enrico Fermi Award, partially rehabilitating his reputation. President Lyndon B. Johnson presented the award after Kennedy's assassination. Oppenheimer continued advocating for international control of atomic energy in his later years.

Personal Life and Relationships: Oppenheimer's romantic relationship with Jean Tatlock, marked by her introduction to radical communist politics, haunted him. Although passionate, they broke up before he joined the Manhattan Project, and Tatlock died by suicide in 1944. In 1939, he met Katherine "Kitty" Puening, a Berkeley student. They married in 1940, had two children, but faced challenges, leading to Kitty's death in 1972.

Legacy and Final Days: A chain smoker, Oppenheimer succumbed to throat cancer on February 18, 1967, in Princeton, New Jersey. In a symbolic move, U.S. Energy Secretary Jennifer Granholm nullified the 1954 decision to revoke Oppenheimer's national security clearance in December 2022, marking a posthumous recognition of his contributions and a complex legacy that continues to be studied and debated.
