Emilio Gino Segrè (30 January 1905 – 22 April 1989) was an Italian physicist and Nobel laureate who discovered the elements technetium and astatine, and the antiproton, a sub-atomic antiparticle, for which he was awarded the Nobel Prize in Physics in 1959. From 1943 to 1946 he worked at the Los Alamos National Laboratory as a group leader for the Manhattan Project. He found in April 1944 that Thin Man, the proposed plutonium gun-type nuclear weapon would not work because of the presence of plutonium-240 impurities.
Born in Tivoli, near Rome, Segrè studied engineering at the University of Rome La Sapienza before taking up physics in 1927. Segrè was appointed assistant professor of physics at the University of Rome in 1932 and worked there until 1936, becoming one of the Via Panisperna boys. From 1936 to 1938 he was Director of the Physics Laboratory at the University of Palermo. After a visit to Ernest O. Lawrence's Berkeley Radiation Laboratory, he was sent a molybdenum strip from the laboratory's cyclotron deflector in 1937 which was emitting anomalous forms of radioactivity. 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, which was the first artificially synthesized chemical element which does not occur in nature.

Emilio Navaira III (born August 23, 1962) is an American musician of Mexican descent, who performs both Country and Tejano music. Known to most by the mononym Emilio, he has charted more than ten singles on the Billboard Hot Latin Tracks charts, in addition to six singles on the Billboard Hot Country Singles & Tracks charts. Emilio is also one of the few Tejano artists to have significant success in both the United States and Mexico, and has been called the "Garth Brooks of Tejano." His biggest country hit was the No. 27 "It's Not the End of the World" in late 1995, and his highest-charting single on any chart is "Por Siempre Unidos," which peaked at No. 7 on Latin Pop Airplay in 1996. Along with Selena, Emilio is one of the most prominent artists to help popularize Tejano music.
Emilio Navaira III was born on August 23, 1962, in San Antonio, Texas to Mexican-American parents, Emilio Navaira Jr., and Mary Navaira. Growing up on the south side of San Antonio, Navaira found early influence in not only tejano legends such as Little Joe y la Familia, Ramón Ayala, and Pedro Infante, but also Lone Star country music heroes such as Willie Nelson, Bob Wills, and George Strait. As a student, Navaira graduated from McCollum High School in 1980, received a music scholarship to Texas State University-San Marcos, and majored in music with plans to become a teacher before ultimately deciding to pursue a career as an artist.
