1945
July 16
On July 16, 1945, at 5:29:45 a.m., the Manhattan Project yields explosive results as the first
atom bomb is successfully tested in Alamogordo, New Mexico.
Plans for the creation of a uranium bomb by the Allies were established as early as 1939, when
Italian emigre physicist Enrico Fermi met with U.S. Navy department officials at Columbia University
to discuss the use of fissionable materials for military purposes. That same year, Albert Einstein
signed a letter to President Franklin Roosevelt supporting the theory that an uncontrolled nuclear
chain reaction had great potential as a basis for a weapon of mass destruction.
In February 1940, the federal government granted a total of $6,000 for research. But in early 1942,
with the United States now at war with the Axis powers, and fear mounting that Germany was
working on its own uranium bomb, the War Department took a more active interest, and limits on
resources for the project were removed.
Brigadier-General Leslie R. Groves, himself an engineer, was now in complete charge of a project to
assemble the greatest minds in science and discover how to harness the power of the atom as a
means of bringing the war to a decisive end. The Manhattan Project (so-called because of where the
research began) would wind its way through many locations during the early period of theoretical
exploration, most importantly, the University of Chicago, where Enrico Fermi successfully set off the
first fission chain reaction. But the Project took final form in the desert of New Mexico, where, in 1943,
Robert J. Oppenheimer began directing Project Y at a laboratory at Los Alamos, along with such minds
as Hans Bethe, Edward Teller, and Fermi. Here theory and practice came together, as the problems of
achieving critical mass—a nuclear explosion—and the construction of a deliverable bomb were worked out.
Finally, on the morning of July 16, in the New Mexico desert 120 miles south of Santa Fe, the first atomic
bomb was detonated. The scientists and a few dignitaries had removed themselves 10,000 yards away to
observe as the first mushroom cloud of searing light stretched 40,000 feet into the air and generated the
destructive power of 15,000 to 20,000 tons of TNT. The tower on which the bomb sat when detonated
was vaporized.
The question now became—on whom was the bomb to be dropped? Germany was the original target, but
the Germans had already surrendered. The only belligerent remaining was Japan.
