Chung-Yao Chao Chung-Yao Chao (; 27 June 1902 – 28 May 1998) was a Chinese physicist. Chung-Yao Chao studied the scattering of gamma rays in lead by pair production in 1930, without knowing that positrons were involved in the anomalously high scattering cross-section. When the positron was discovered by Carl David Anderson in 1932, confirming the existence of Paul Dirac's "antimatter", it became clear that positrons could explain Chung-Yao Chao's earlier experiments, with the gamma rays being emitted from electron-positron annihilation.

LeRoy Apker LeRoy W. Apker (June 11, 1915 – July 5, 1970) was an American experimental physicist. Along with his colleagues E. A. Taft and Jean Dickey, he studied the photoelectric emission of electrons from semiconductors and discovered the phenomenon of exciton-induced photoemission in potassium iodide. In 1955, he received the Oliver E. Buckley Condensed Matter Prize of the American Physical Society for his work.

Philip Warren Anderson Philip Warren Anderson (born December 13, 1923) is an American physicist and Nobel laureate. Anderson has made contributions to the theories of localization, antiferromagnetism, symmetry breaking (including a seminal paper in 1962 discussing symmetry breaking in particle physics, leading to the development of the Standard Model around 10 years later), and high-temperature superconductivity, and to the philosophy of science through his writings on emergent phenomena.
