DID YOU KNOW Albert Einstein and Leo Szilard’s letter to President Franklin D. Roosevelt in 1939 gave birth to the Manhattan Project, one of the most destructive projects in history. It was during this project that the atomic bomb was made which destroyed the cities of Nagasaki and Hiroshima, Japan.
The letter, addressed to President Roosevelt, contained a warning about the potential for deadly weapons that could be developed from nuclear reactions.
What prompted Einstein and Szilard to write this letter was the fear that Nazi Germany was pursuing research that could lead the world to a major catastrophe. The letter was not only a warning, but also encouraged the United States to create a project that would later give birth to the world’s first atomic bomb.

Even though it only consists of a few pages of letters, its impact goes far beyond just scribbles on paper and ink. In the letter, Einstein and Szilard warned Roosevelt about the potentially destructive power of nuclear energy.
They urged the US government to act immediately before it was too late, and as a result, history witnessed one of the world’s most dangerous arms races.
Letter Writing Background
On October 11, 1939, physicists Einstein and Szilard sent an important letter to the President of the United States, Roosevelt. The letter is one of the historic documents warning about the potential use of atomic energy for military purposes.

This letter not only encouraged the United States to begin scientific research that later led to the creation of the atomic bomb, but also became a starting point that had a major influence on the world nuclear arms race.
Leo Szilard was a physicist who was very worried that Nazi Germany, which at that time was trying to control Europe, would use the latest science about nuclear energy to create weapons of mass destruction.
These concerns deepened after Germany banned uranium exports from Czechoslovakia. Szilard, along with Einstein, felt the need to act quickly and send a warning to the Roosevelt administration so that the US would not fall behind in the development of nuclear technology.

Important Contents of the Letter
Einstein-Szilard’s letter provides an explanation of the enormous potential of nuclear chain reactions which can produce large amounts of energy. They highlighted that the element uranium, if used in sufficient quantities, could trigger a very powerful explosion.
They also warned that if Germany succeeded first in building an atomic bomb, it would give it unrivaled power in war. This letter clearly recommended that the US government immediately begin intensive research to explore the possibility of creating nuclear weapons.
As the letter was sent, Roosevelt responded quickly and seriously. A few weeks after the letter was received, a Uranium Advisory Committee was formed to begin further research.

This was the first step that led to the Manhattan Project, the secret program that ultimately produced the world’s first atomic bomb. The impact of the letter was enormous, as it encouraged the US to invest in the development of nuclear weapons in the midst of World War II.
The Importance of This Letter in World Nuclear History
Einstein-Szilard’s letter not only moved the US government to act quickly, but also marked the beginning of an era in the nuclear arms race that continues to this day. Although the message was short, it contained a warning about how new technology could be misused if it fell into the wrong hands.
In the letter, Einstein and Szilard described the enormous destructive potential of nuclear weapons in frightening detail, making this letter considered one of the most important letters of the 20th century.
After learning of the enormous negative impact, Einstein, who signed the letter, regretted having contributed to the development of nuclear weapons. He stated that writing the letter to Roosevelt was one of the biggest mistakes of his life. He regretted that this letter ultimately became the catalyst for the development of the atomic bomb that was used to destroy Hiroshima and Nagasaki at the end of World War II.
Today, the Einstein-Szilard letter remains an important document in world nuclear history. This letter not only changed the course of World War II, but also brought us to a new era in human history, an era where nuclear weapons posed a major threat to human survival.
The legacy of this letter highlights the importance of balance between scientific progress and moral considerations that must always be taken into account in decision making. (Z-3)
