Fermi was born in Rome, Italy, on September 29, 1901. The son of a railroad
official, he studied at the University of Pisa from 1918 to 1922 and later
at the universities of Leyden and Gottingen. He became professor of theoretical
physics at the University of Rome in 1927.
Fermi's accomplishments were in both
theoretical and experimental physics, a unique feat in an age in which
scientific endeavors have tended to specialize on one aspect or the other.
In 1933, he developed the theory
of beta decay, postulating that the newly-discovered neutron decaying to
a proton emits an electron and a particle which he called a "neutrino".
The theory developed to explain this interaction later resulted in recognition
of the weak interaction force. Investigation into the weak force has been
one of the major areas of study at Fermilab.
Experimentally, Enrico Fermi and
his colleagues, during the early 1930's, studied in detail the theory of
neutrons; they bombardedmost of the elements in the periodic table with
them. They slowed down the neutrons, and among other things, produced a
strange new product when bombarding uranium with neutrons which later was
recognized to be a splitting of the uranium atoms.
Enrico Fermi received the Nobel Prize
in 1938 for "his discovery of new radioactive elements produced by neutron
irradiation, and for the discovery of nuclear reactions brought about by
slow neutrons." Fermi and his family used the opportunity offered by his
trip to Sweden for the awards ceremonies to come to the United States where
Fermi accepted a position as professor of physics at Columbia University.
At that time it was recognized that
nuclear fission (the splitting of the atom) had taken place in Fermi's
and other similar experiments. Scientists felt that this principle might
be applied to construct an "atomic bomb". With World War II raging in Europe,
the ability to produce such a bomb was of the greatest importance in the
balance of power in the world.
Fermi moved to the University of
Chicago to be in charge of the first major step in making feasible the
building of the
bomb. In the squash courts under the west stand of the University's
Stagg Field, Fermi supervised the design and assembly of an "atomic pile",
a code word for an assembly that in peacetime would be known as a "nuclear
reactor". Today, a plaque at the site reads: "On December 2, 1942, man
achieved here the first self-sustaining chain reaction and thereby initiated
the controlled release of nuclear energy." He was the prime mover in the
design of the synchrocyclotron at the university which was, at the time
of its completion, one of the most powerful atom smashers in the world.
Fermiís momentous accomplishments
caused him to be recognized as one of the great scientists of the 20th
century. Following his death on November 28, 1954, a number of science
institutions and awards have been named in his honor.
