									Manhattan Project
 Developing the Atomic Bomb
 Elements of this PowerPoint were downloaded from www.SlideShare.net
   Gain an
    understanding of the
    development and
    use of the first
    atomic bombs.
Manhattan Project
            The Manhattan project
             not only helped bring an
             end to World War II, but
             it also advanced the
             knowledge of the atomic
             age and determined how
             future wars would be

                                United States.
                 Albert Einstein
   In 1939, Albert Einstein
    wrote a letter to
    President Franklin
    Roosevelt warning that
    Germany was secretly
    trying to develop an
    atomic bomb and urged
    U.S to do likewise.
Einstein’s Letter
President Franklin Roosevelt
                 Roosevelt wrote Einstein
                  back informing him that he
                  immediately set up a
                  committee to begin atomic
                 FDR believed the United
                  States could not take the
                  risk of waiting and
                  allowing Hitler to have the
                  power of developing the
                  first atomic bomb.
   Research and production
    sites of the Manhattan
    Project were located all
    across the United States.
   Laboratories and
    manufacturing facilities
    were secretly constructed
    just for project.
Main project research locations of the United States
     Many people were involved
      in the project including
      administrators, researchers,
      scientists, and more.

     Bottom Picture: J. Robert
      Oppenheimer, Enrico Fermi, and
      Ernest Lawrence
          J. Robert Oppenheimer
   Oppenheimer eagerly
    joined the project at
    Lawrence's Radiation
    Laboratory at Berkeley.
   In June 1942 he was
    appointed the scientific
    director of the Project.
   He managed over 3,000
    people and is often
    referred as the “father”
    of the atomic bomb.
Enrico Fermi
         Born in Italy, Fermi
          created a nuclear fission
          chain reaction, which
          was critical to creating
          the atomic bomb.
         In 1944, he joined the
          Manhattan Project and
          was the overseer of the
Ernest Lawrence
           During WWII, Lawrence
            was in charge of the
            separation work at Oak
            Ridge which provided
            uranium 235 for the
            atomic bomb .
           He was known as the
            “Atomic Smasher” and
            the man who “held the
            key” to atomic energy.
                  The Trinity Test
   On July 16, 1945, the first
    atomic bomb was exploded
    at the Alamogordo air base
    near Albuquerque, NM.
   A ball of fire rose rapidly,
    followed by a mushroom
    cloud extending to 40,000
   The bomb generated an
    explosive power equivalent
    to 20,000 tons of TNT.
                                              The Trinity Test resulted
                                               in great success.
                                              This was the world’s first
                                               ever atomic explosion.
                                              After President Harry
                                               Truman received the
                                               word, he knew the
                                               atomic bomb would
                                               create a great advantage

receiving word that the Trinity Test was
                                               in World War II.
a success.
    Use of Atomic Bombs in WWII
   It was finally decided to use
    the atomic bomb in the war
    and two more atomic bombs
    were created by the project.
   The uranium “Little Boy”
    bomb was dropped on
    Hiroshima on August 6,
   The plutonium “Fat Boy”
    bomb was dropped on
    Nagasaki on August 9, 1945.
        President Harry
         Truman’s decision to
         drop the atomic bomb is
         one of the most
         controversial issues in
         American History.
        The creation of the
         Atomic Bomb helped
         bring an end to World
         War II.
