Timeline of the Manhattan Project - Wikipedia

US President Franklin D. Roosevelt was presented with a letter signed by Albert Einstein (transcribed by Leo Szilard) on October 11, 1939, which urged the United States to rapidly develop an atomic bomb program. The president agreed. The Navy awarded Columbia University the first Atomic Energy funding of $6,000, which grew into the Manhattan Project under Oppenheimer and Enrico Fermi's work.

Have students begin to outline some of the social and political changes that resulted from the Manhattan Project. This provides a good bridge to lectures on 1950s America. Topics to consider include the arms race and Cold War, nuclear power, and the growth of connections between government and the scientific community.

The events surrounding the invention and use of two atomic weapons by the United States on Japan during WWII are among the most controversial and significant developments in modern American history. For this reason, the topic provides a superb lesson for exploring the role of technology in society. In response to developments in Germany, president Franklin Roosevelt ordered the creation of an atomic weapon. Dubbed the Manhattan Project, this secret endeavor brought together scientists and engineers in a $2 billion effort that led to the creation of two atomic weapons and ushered in the nuclear age.

The Nagasaki bomb, Fat Man, in contrast, consisted primarily of plutonium-239, a synthetic element which could be induced to supercriticality only by implosion. The design of an implosion device was at the center of the efforts by physicists at Los Alamos during the Project.

This process was calledcompartmentalization, and as a result some top scientistsworking on the project did not know the ultimate goal was to buildatomic bombs.

It was directed by American physicist Dr

By the summer of 1945, Oppenheimer was ready to test the first bomb. On July 16, 1945, at near , scientists of the Manhattan Project readied themselves to watch the detonation of the world's first atomic bomb. The device was affixed to a 100-foot tower and discharged just before dawn. No one was properly prepared for the result.
