Chien-Shiung Wu (1912-1997), Chinese-US physicist. Wu studied in China before moving to the US in 1936. She worked at various universities and became professor of physics at Columbia in 1957. In her research she demonstrated that the direction of emission of beta rays in radioactive decay is correlated with the direction of spin of the emitting nucleus, showing that parity is not conserved. This confirmed Tsung Dao Lee's theory. Lee and Yang shared the Nobel prize for their work while Wu was overlooked but received the 1978 Wolf Prize in Physics for her work. Wu also experimentally confirmed other theories in elementary particle physics, as well as studying the X-ray spectra of muonic atoms.
