When you hear the phrase “father of the atomic bomb,” you might think of Robert Oppenheimer, the leader of the Manhattan Project. He famously reacted to the first atomic bomb test by saying, “Now I am become Death, destroyer of worlds.” But there’s another scientist who played a crucial role in nuclear physics and could have changed history in 1934. This scientist is Enrico Fermi, a key figure in the development of nuclear technology.
Enrico Fermi was born in Rome on September 29, 1901, into a family that valued education. His father worked as a railway inspector, and his mother, Ida, was a teacher who believed in the power of knowledge. Unlike most families at the time, they weren’t Catholic and sent Fermi to a secular school. From a young age, Fermi excelled in school, especially in math and science, thanks to his mother’s encouragement. He loved building electric motors with his brother Giulio, but tragedy struck when Giulio died during surgery in 1915. This loss deeply affected Fermi, driving him to focus even more on his studies.
In 1918, Fermi applied to the prestigious Scuola Normale Superiore in Pisa. He impressed the examiners with a paper that was exceptional for someone his age, earning him a spot in the doctoral program. Fermi quickly proved himself a natural talent in physics.
As Fermi advanced in his career, Italy was undergoing political changes with Benito Mussolini’s rise to power. Fermi remained focused on his academic work, earning scholarships and teaching in Germany and the Netherlands. By 1926, he returned to Italy and became a professor of theoretical physics at the University of Rome at just 25. He developed Fermi-Dirac statistics, which helped explain the behavior of subatomic particles.
In 1929, Mussolini appointed Fermi to the Accademia dei Lincei, giving him a significant salary and the title of “excellency.” Fermi’s research continued to thrive, and he nearly provided Mussolini with the key to the atomic bomb.
In 1934, Fermi and his team made a groundbreaking discovery while researching uranium, taking the first step toward nuclear fission. This could have led to nuclear weapons being developed in Italy, potentially giving Nazi Germany an advantage. However, Fermi mistakenly thought he had created a new element, and by the time the true implications were understood, the opportunity for Germany to gain a head start had passed.
Fermi won the Nobel Prize for Physics in 1938, but that same year, Mussolini’s anti-Jewish laws targeted Fermi’s wife and children. This prompted Fermi to move to the United States, where he continued his groundbreaking work.
Arriving in New York City in January 1939, Fermi quickly made significant contributions to nuclear research. He demonstrated that emitting neutrons into uranium undergoing fission could trigger a chain reaction. His work caught the attention of the U.S. government, leading to increased interest in nuclear weapons research after the attack on Pearl Harbor in December 1941.
In the summer of 1942, Fermi moved to Chicago, where he built the first nuclear reactor, known as Chicago Pile-1. This marked the beginning of the atomic age. Fermi became a U.S. citizen in 1944 and joined the Manhattan Project, working alongside Robert Oppenheimer.
Fermi was present during the Trinity test in July 1945, where the first plutonium bomb was tested. Unlike Oppenheimer, who reflected on the weapon’s destructive power, Fermi focused on the scientific aspects of the test. He supported using atomic weapons against Japan, believing it was necessary to end the war.
On August 6, 1945, the first atomic bomb was dropped on Hiroshima, followed by another on Nagasaki three days later. The devastation led to Japan’s surrender and the end of World War II.
After the war, Fermi returned to academia, focusing on elementary particles and cosmic rays. He famously asked, “Where is everybody?” during a discussion about extraterrestrial life, a question now known as the Fermi Paradox.
In 1949, Fermi joined the General Advisory Committee to the Atomic Energy Commission, where he expressed concerns about developing thermonuclear weapons. Despite his reservations, he continued to work on these projects.
Fermi passed away on November 28, 1954, at the age of 53. His legacy lives on through the Fermi Paradox and the element fermium. Despite facing numerous challenges, Fermi’s contributions to science and humanity remain significant, shaping the world in profound ways.

**Sanitized Transcript:**
Who do you think of when you hear the words “father of the atomic bomb”? We’re guessing it’s Robert Oppenheimer, the leader of the Manhattan Project who famously responded to the first atomic bomb test by declaring, “Now I am become Death, destroyer of worlds.” But what if we told you there was another contender? A scientist who came close to making a significant breakthrough in 1934 that could have resulted in Nazi Germany developing the world’s first nuclear weapon. The scientist who almost created this alternative reality was Enrico Fermi, a pivotal figure in the development of nuclear physics.
Fermi was a leading light in both experimental and theoretical physics, known for his extraordinary intellect. He built the first operational nuclear reactor in 1942, contributed to our understanding of subatomic particles known today as fermions, and assisted Oppenheimer in the development of the atomic bomb. From fascist Italy to WWII America, this is the life of Enrico Fermi, one of the greatest Italian scientists.
**The Early Years**
One theme we’ve touched on is that, despite what fiction tells you, you usually can’t tell which child is going to grow up to change the world. Enrico Fermi was one of those kids. Born in Rome on September 29, 1901, Fermi came from an average family. His father was a government railway inspector, while his mother, Ida, was a teacher who believed acquiring knowledge was a sacred duty. Unusually for the time, the family wasn’t Catholic and sent young Fermi to one of the few secular schools in Rome.
From the moment he started school, Fermi was consistently at the top of his class. His mother instilled in him a deep love for math, science, and engineering. When not studying, he spent his time building electric motors with his older brother, Giulio. However, a tragedy struck when Giulio died during routine surgery in 1915. This loss deeply affected Fermi, leading him to withdraw into his studies.
In 1918, three years after Giulio’s death, Fermi applied to the prestigious Scuola Normale Superiore in Pisa. He excelled in the entrance exam, impressing the examiners with a paper that would have been remarkable for a doctoral thesis. Fermi was fast-tracked into the school’s doctoral program, quickly proving to be a natural talent in physics.
**Breaking Italy**
As Fermi was rising through the physics profession, another Italian, Benito Mussolini, founded the Fascist Party in 1919. While Mussolini was gaining power, Fermi remained apolitical, focused solely on his academic pursuits. He graduated with honors and received a government grant to continue his studies.
Between 1922 and 1926, Fermi won scholarships and taught in Germany and the Netherlands. By 1926, he returned to Italy and was appointed to the chair of theoretical physics at the University of Rome at just 25 years old. His groundbreaking work included the development of Fermi-Dirac statistics, which helped explain the behavior of subatomic particles.
In 1929, Mussolini appointed Fermi to the Accademia dei Lincei, granting him a significant salary and the title of “excellency.” Fermi’s work continued to flourish, and he came close to providing Mussolini with the key to the atomic bomb.
**Fathering the Bomb**
In 1934, Fermi and his team were researching uranium and discovered the first step toward nuclear fission. This breakthrough could have led to nuclear weapons being developed in Italy, potentially giving Nazi Germany a significant advantage. However, Fermi believed he had created a new element, and by the time the true implications were understood, the opportunity for Germany to gain a head start on nuclear weapons had passed.
Fermi was awarded the Nobel Prize for Physics in 1938, but that same year, Mussolini enacted anti-Jewish laws that targeted Fermi’s wife and children. This prompted Fermi to leave Italy for the United States, where he continued his groundbreaking work.
**A New Home**
Upon arriving in New York City in January 1939, Fermi quickly made significant contributions to nuclear research. He demonstrated that emitting neutrons into uranium undergoing fission could trigger a chain reaction. His work caught the attention of the U.S. government, leading to increased interest in nuclear weapons research following the attack on Pearl Harbor in December 1941.
Fermi arrived in Chicago in the summer of 1942, where he assembled the first nuclear reactor, known as Chicago Pile-1. This marked the dawn of the atomic age. Fermi became a naturalized U.S. citizen in 1944 and joined the Manhattan Project, working under Robert Oppenheimer.
**The Atomic Bomb**
Fermi was present during the Trinity test in July 1945, where the first plutonium bomb was tested. Unlike Oppenheimer, who reflected on the destructive power of the weapon, Fermi noted the scientific interest of the test. He continued to advocate for the use of atomic weapons against Japan, believing it was a necessary step to end the war.
On August 6, 1945, the first atomic bomb was dropped on Hiroshima, followed by another on Nagasaki three days later. The devastation was unprecedented, leading to Japan’s surrender and marking the end of World War II.
**Later Years and Legacy**
After the war, Fermi returned to academia, focusing on elementary particles and cosmic rays. He famously posed the question, “Where is everybody?” during a discussion about extraterrestrial life, which became known as the Fermi Paradox.
In 1949, Fermi joined the General Advisory Committee to the Atomic Energy Commission, where he expressed concerns about the development of thermonuclear weapons. Despite his reservations, he continued to work on these projects.
Fermi passed away on November 28, 1954, at the age of 53. His legacy lives on through the Fermi Paradox and the element fermium. While he faced numerous challenges throughout his life, Fermi’s contributions to science and humanity remain significant, shaping the world in profound ways.
