Life With The Bomb

A Historical Summary of The Manhattan Project, and Its Global Significance

Luca Oliver-Green

Forward/History

There were many events leading up to the discovery of nuclear fission. Even though fission opened the door for nuclear power and weaponry, its scientific discovery was based on a different theory. If you were to think of this entire stem of history as if it was an explosion itself, Otto Hahn, Lise Meitner, and Fritz Strassmann would evidently be the spark lightning the fuse. These three scientists brought together by the intriguing new possibilities of radioactivity, would eventually find the key to unlocking one of the most important scientific discoveries of their time.

This photograph was taken at Dr. Meitner's home in Cambridge, UK, when she received the Enrico Fermi award for 1966, shared with Hahn and Strassmann.

1931 — Heavy Hydrogen or Deuterium is discovered by Harold C. Urey.

1932 — The atom is split by John Crockcroft and E.T.S. Walton of Great Britain, thereby proving Einstein's Theory of Relativity.

1933 — Hungarian physicist Leo Szilard realizes the possibility of the nuclear chain reaction.

1934 — The first nuclear fission is achieved by Enrico Fermi of Italy.

1939 — The Theory of Nuclear Fission is announced by Lise Meitner and Otto Frisch.

January 26, 1939

This particular date marks the start of something powerful. On the 26th of January, at the George Washington University, Neil’s Bohr announces of the findings of Otto Hahn, Lise Meitner, and Fritz Strassmann. The result of this new scientific break through is “fission,” releasing two hundred million electron volts of energy. (200 MeV) The announcement came just weeks after Otto Hahn and Fritz Strassmann, two of Bohr’s colleagues in Copenhagen, reported that they had discovered the element Barium after bombarding Uranium with neutrons.

January 29, 1939

On the 29th of January J. Robert Oppenheimer hears about the discovery of fission. Within a few minutes, he realizes that excess neutrons must be emitted, and that it might be possible to build a nuclear chain reaction. By the time the Manhattan Project was launched in the fall of 1942, Oppenheimer was already considered an exceptional theoretical physicist and had become deeply involved in exploring the possibility of an atomic bomb.

Julius Robert Oppenheimer was an American theoretical physicist and a professor of physics at the University of California, Berkeley. Later on Oppenheimer became the wartime head of the Los Alamos Laboratory and is often credited as being, “the father of the atomic bomb.”

August 2, 1939

Leo Szilard

Leo Szilard moved to the United States in 1938, where he worked with Enrico Fermi and Walter Zinn on means of creating a nuclear chain reaction. On August 2, 1939, after working tirelessly with fellow Hungarian physicists Edward Teller and Eugene Wigner, Szilard wrote a letter warning the Franklin D. Roosevelt that Germany might be developing atomic bombs and that the United States should start its own nuclear program. To get this message directly to FDR Leo needed a signature from Albert Einstein, a celebrity inside and outside of the science world. FDR and Einstein also had a previous relationship, so his signature would also help to make sure the letter was taken in a non threatening way. When he was brought the letter, Einstein just nodded his head and signed.

Leo Szilard was a Hungarian-American physicist and inventer. He theorized the nuclear chain reaction, and patented the idea for something he called a non-fission reactor. Possibly one of his most significant creations, was that he wrote the letter for Albert Einstein’s signature that resulted in the creation of the Manhattan Project

The Letter

September 1, 1939

On September 1, 1939 Germany invaded Poland, this led Britain and France to declare war on Hitler’s Nazi state in retaliation. From the invasion of Poland until the war ended with Japan’s surrender in September 1945, most nations around the world were engaged in armed combat.

Even though America didn’t start to fight in the war until much later, the start of the war became just the pressure Leo Szilard needed to get his letter signed. Although in many historical pieces they quote FDR as being “a man of action,” some might wonder what choice he really had faced with a possible world war.
