  Emilio G. Segrè - Wikipedia, the free encyclopedia
Segrè was appointed assistant professor of physics at the University of Rome in 1932 and served until 1936.
After careful chemical and theoretical analysis, Segrè was able to prove that some of the radiation was being produced by a previously unknown element, dubbed technetium, and was the first artificially synthesized chemical element which does not occur in nature.
However, in Segrè's recollection, when Lawrence learned that Segrè was legally trapped in California, he dropped his pay to $116 a month (which many, including Segrè, saw as exploiting the situation).

 Segrè, Emilio
In 1932 Segrè was appointed assistant professor of physics at the University of Rome, and two years later he participated in neutron experiments directed by Fermi, in which many elements, including uranium, were bombarded with neutrons, and elements heavier than uranium were created.
Segrè left Rome in 1936 to become director of the physics laboratory at the University of Palermo.
From 1943 to 1946 Segrè was a group leader at the Los Alamos Scientific Laboratory, Los Alamos, N.M. He was naturalized as a U.S. citizen in 1944 and was professor of physics at Berkeley (1946-72).

In 1888 Segre succeeded D'Ovidio to the chair of higher geometry in Turin and he continued to hold this post for the next 36 years until his death.
In a paper published in 1896, Segre found an invariant of surfaces under birational transformations which had appeared in a different form in a 1871 article by Zeuthen: this invariant is now called the Zeuthen-Segre invariant.
Segre's contribution to the knowledge of space assures him a place after Cremona in the ranks of the most illustrious members of the new Italian school of geometry.

Physicist of both Italian and American nationalities, winner of Physics Nobel Prize of 1959, together with Owen Chamberlain, for proving the existence of the antiproton, Segrè was born in Tivoli, a town near Rome, in February 1st 1905, and died in Lafayette, California, in April 22nd 1989.
Segrè entered the University of Rome in 1922 as engineering student, and than changed to Physics, being Enrico Fermi's first Ph.D. student.
Segrè and Chamberlain proved the existence of the antiproton, in 1955, while trying to create antiprotons (protons with negative charge instead of the normal positive charge) in a powerful particle accelerator.

 Emilio Segrè: nuclear pioneer (February 2005) - Physics World - PhysicsWeb
On the centenary of his birth, Emilio Segrè is remembered for his discovery of the antiproton and several chemical elements, not to mention his knack of bringing physics to life
This is how Emilio Segrè described the birth of the atomic age on 15 July 1945.
Segrè could not recall what they said to each other at the time, but he remembered that Fermi got up almost immediately and began dropping small scraps of paper to estimate the intensity of the explosion by measuring how far the scraps were moved by the shock wave.

This book, the autobiography of Italian physicist and Nobel Prize winner Emilio Segrè, recounts his professional and personal life fully, including detailed descriptions of his encounters with many of his notable contemporaries.
Segrè is known for his scientific collaborations with Enrico Fermi on slow neutron physics, his radiochemical work in discovering several new elements, and for the discovery of the antiproton.
He emigrated to the United States from Italy in 1938 to work at the Radiation Laboratory at the University of California, Berkeley, and was recruited by J. Robert Oppenheimer in 1943 to join the Manhattan Project.

 The New York Review of Books: EMILIO SEGRE
Anyone with a relatively good knowledge of twentieth-century physics knows that Segrè's work and contribution to physics were anything but negligible.
In his book—published posthumously—Segrè writes, "I tell the truth the way it was and not the way many of my colleagues wish it had been." In Segrè's version of the truth there were a large number of very negative judgments made about "colleagues" who did not have the chance to defend themselves.
Segrè's "work and contribution" were negligible compared to some, and substantial compared to others.

The photograph was taken at Lawrence Berkeley Laboratory in October, 1955 at the time of the discovery of the antiproton.
To detect the particles, Segrè and Chamberlain devised a maze of magnets and electronic counters through which only antiprotons could pass.

And what can we learn from neutrinos, the subatomic "messages from the sun" that may hold the key to understanding the birth-and death-of our solar system?
In answering these and hundreds of other temperature-sensitive questions, Segrè presents an uncanny view of the world around us.
