This section provides an overview of the history of the Manhattan Project, the key organizations involved, the science behind the bomb, and more.
In 1939, Albert Einstein sent FDR a letter urging the US conduct research into an atomic bomb.
Soon after the Interim Committee concluded that the atomic bomb should be used as soon as possible against Japan, a group of scientists led by physicist James Franck founded a committee to study the question of the bomb's use.
Before computers became the modern electric desktops or laptops of today, “computers” actually referred to the people who did computing or calculations of equations.
As the Manhattan Project neared its first atomic test, there was a growing sentiment among project leaders that an advisory committee to make recommendations on nuclear energy should be created.
What was the Manhattan Project?
Since 1945, the Manhattan Project has frequently appeared in films, fiction, and many other forms of popular culture.
While the secrecy of the Manhattan Project meant that the U.S. Army was the only branch officially charged with overseeing it, the Navy would also play a crucial role in the project’s success.
The tragic story of the "radium girls" had an important impact on the Manhattan Project.
The trial and execution of Julius and Ethel Rosenberg for passing atomic secrets to the Soviet Union remains controversial today.
