“Yang Chen Ning, known as Frank Yang (b. 1922) Chinese-U.S. theoretical physicist. He emigrated to the U.S. in 1945 and studied with E. Teller at the Univ. of Chicago. He showed that parity is violated when elementary particles decay. This and other work in particle physics earned him and Tsung-Dao Lee (b. 1926) a 1957 Nobel Prize. His research focused mostly on interactions involving the weak force among elementary particles. He also worked in statistical mechanics.”
