ERNEST T.S. WALTON Signed b/w photograph of Walton from the shoulders up in suit-and-tie Photograph inscribed and signed: "Tony/from E.T.S. Walton" in blue ink. B/w, 5½x3½. Walton (1903-1995) was an Irish physicist who shared the 1951 Nobel Prize in Physics with Sir John D. Cockcroft for developing the first particle accelerators in the 1930's. As of this biography, Walton is the only Irishman to receive a Nobel Prize for science. Before the development of particle accelerators, physicists could only study relatively low-energy particles, like those released during natural radioactive decay. The development of particle accelerators allowed physicists to search for highly exotic particles in the collision debris of high-speed, heavy atomic nuclei and have been instrumental in the search for a "grand unified theory" of quantum physics and relativity. Walton and Cockcroft successfully developed and used their first accelerator in 1932 while at Trinity College in Cambridge. They used it to slam protons into lithium atoms at energies of 710,000 electron volts. (By comparison, CERN's Large Hadron Collider is designed to generate energies around seven tera-electron volts; that's a 7 with 12 zeroes after it) After earning his doctorate at Cambridge, he returned to his alma mater Trinity College in Dublin, where he was a fellow for the next 40 years and a fellow emeritus after that. He was also Erasmus Smith professor of natural and experimental philosophy from 1946 to 1976 there, as well as chairman of the School of Cosmic Physics at the Dublin Institute for Advanced Studies after 1952. Lightly scuffed near right and left edges (not visible from head on). Otherwise in fine condition.
