CHICAGO, Nov. 28--Dr. Enrico Fermi, an architect of the atomic age and Nobel Prize winner, died at his home here this morning of cancer. His age was 53. He had undergone what was described as an...
Enrico Fermi ( Italian: [enˈriːko ˈfermi]; 29 September 1901 – 28 November 1954) was an Italian and later naturalized American physicist, renowned for being the creator of the world's first nuclear reactor, the Chicago Pile-1, and a member of the Manhattan Project. He has been called the "architect of the nuclear age " [1] and the ...

Enrico Fermi (born Sept. 29, 1901, Rome, Italy—died Nov. 28, 1954, Chicago, Illinois, U.S.) Italian-born American scientist who was one of the chief architects of the nuclear age. He developed the mathematical statistics required to clarify a large class of subatomic phenomena, explored nuclear transformations caused by neutrons, and directed the f...
Fermi’s father, Alberto Fermi, was a chief inspector of the government railways; his mother was Ida de Gattis, a schoolteacher. In 1918 Enrico Fermi won a scholarship to the University of Pisa’s distinguished Scuola Normale Superiore, where his knowledge of recent physics benefited even the professors. After receiving a doctorate in 1922, Fermi use...
Fermi returned home to Italy in 1924 to a position as a lecturer in mathematical physics at the University of Florence. His early research was in general relativity, statistical mechanics, and quantum mechanics. Examples of gas degeneracy (appearance of unexpected phenomena) had been known, and some cases were explained by Bose-Einstein statistics, which describes the behaviour of subatomic particles known as bosons. Between 1926 and 1927, Fermi and the English physicist P.A.M. Dirac independently developed new statistics, now known as Fermi-Dirac statistics, to handle the subatomic particles that obey the Pauli exclusion principle; these particles, which include electrons, protons, neutrons (not yet discovered), and other particles with half-integer spin, are now known as fermions. This was a contribution of exceptional importance to atomic and nuclear physics, particularly in this period when quantum mechanics was first being applied.
This seminal work brought Fermi an invitation in 1926 to become a full professor at the University of Rome. Shortly after Fermi took up his new position in 1927, Franco Rasetti, a friend from Pisa and another superb experimentalist, joined Fermi in Rome, and they began to gather a group of talented students about them. These included Emilio Segrè, Ettore Majorana, Edoardo Amaldi, and Bruno Pontecorvo, all of whom had distinguished careers. Fermi, a charismatic, energetic, and seemingly infallible figure, clearly was the leader—so much so that his colleagues called him “the Pope.”

In 1929 Fermi, as Italy’s first professor of theoretical physics and a rising star in European science, was named by Italian Prime Minister Benito Mussolini to his new Accademia d’Italia, a position that included a substantial salary (much larger than that for any ordinary university position), a uniform, and a title (“Excellency”).
During the late 1920s, quantum mechanics solved problem after problem in atomic physics. Fermi, earlier than most others, recognized that the field was becoming exhausted, however, and he deliberately changed his focus to the more primitively developed field of nuclear physics. Radioactivity had been recognized as a nuclear phenomenon for almost two decades by this time, but puzzles still abounded. In beta decay, or the expulsion of a negative electron from the nucleus, energy and momentum seemed not to be conserved. Fermi made use of the neutrino, an almost undetectable particle that had been postulated a few years earlier by the Austrian-born physicist Wolfgang Pauli, to fashion a theory of beta decay in which balance was restored. This led to recognition that beta decay was a manifestation of the weak force, one of the four known universal forces (the others being gravitation, electromagnetism, and the strong force).

Obituary. Enrico Fermi, 1901-1954. E. Bretscher. and. John Douglas Cockcroft. Published: 01 November 1955 https://doi.org/10.1098/rsbm.1955.0006. Abstract. The sudden death of Enrico Fermi at the age of 53 has filled physicists all the world over with greatest sadness and consternation.
Enrico Fermi died in Chicago from stomach cancer on November 28, 1954. Since then, space exploration has grown and increased, and now, cosmic rays in space are being examined directly. Hardware to artificially create cosmic rays is no longer essential, but those developing new theories stand on the shoulders of Fermi in extending knowledge of ...
