Title: Nobel Prize controversies
Content: a CERN preprint. Israeli physicist Yuval Ne'eman published the classification of hadrons through their SU(3) flavor symmetry independently of Gell-Mann in 1962, and also felt that he had been unjustly deprived of the prize for the quark model. The 1956 prize went to John Bardeen, Walter Houser Brattain and William Bradford Shockley "for their researches on semiconductors and their discovery of the transistor effect". However, the committee did not recognize numerous preceding patent applications. As early as 1928, Julius Edgar Lilienfeld patented several modern transistor types. In 1934, Oskar Heil patented a field-effect transistor. It is unclear whether Lilienfeld or

Title: John Bardeen
Content: John Bardeen John Bardeen (; May 23, 1908 – January 30, 1991) was an American physicist and electrical engineer. He is the only person to be awarded the Nobel Prize in Physics twice: first in 1956 with William Shockley and Walter Brattain for the invention of the transistor; and again in 1972 with Leon N Cooper and John Robert Schrieffer for a fundamental theory of conventional superconductivity known as the BCS theory. The transistor revolutionized the electronics industry and ushered the birth of the Information Age. The semiconductor device also made possible the development of almost every modern electronic device,

Title: Herbert Kroemer
Content: Herbert Kroemer Herbert Kroemer (born August 25, 1928), a professor of electrical and computer engineering at the University of California, Santa Barbara, received his Ph.D. in theoretical physics in 1952 from the University of Göttingen, Germany, with a dissertation on hot electron effects in the then-new transistor, setting the stage for a career in research on the physics of semiconductor devices. In 2000, Kroemer, along with Zhores I. Alferov, was awarded the Nobel Prize in Physics "for developing semiconductor heterostructures used in high-speed- and opto-electronics". The other co-recipient of the Nobel Prize was Jack Kilby for his invention and development

Title: John Bardeen
Content: John Bardeen (1908–1991) shared the Nobel Prize in Physics twice — in 1956, as co-inventor of the transistor and in 1972, for the explanation of superconductivity. The transistor paved the way for all modern electronics, from computers to microchips. Diverse applications of superconductivity include infrared sensors and medical imaging systems." The other scientists on the "American Scientists" sheet include biochemist Gerty Cori, chemist Linus Pauling and astronomer Edwin Hubble.
