Uranium-235 which might be used to build an atomic bomb. Shortly after

that the United States Government began work on the Manhattan Project.

The Manhattan Project was the code name for the United States effort

to develop the atomic bomb before the Germans did. "The first

successful experiments in splitting a uranium atom had been carried

out in the autumn of 1938 at the Kaiser Wilhelm Institute in

Berlin"(Groueff 9) just after Einstein wrote his letter. So the race

was on. Major General Wilhelm D. Styer called the Manhattan Project

"the most important job in the war . . . an all-out effort to build an

atomic bomb."(Groueff 5) It turned out to be the biggest development

in warfare and science's biggest development this century. The most

complicated issue to be addressed by the scientists working on the

Manhattan Project was "the production of ample amounts of 'enriched'

without fissioning and become Uranium-239. "But the Uranium-239 thus

would be placed in "a gigantic, 214-ton, cylinder-shaped tank (called
