Chien-Shiung Wu
Chien-Shiung Wu (simplified Chinese: 吳健雄; traditional Chinese: 吳健雄; pinyin: Wú Jiànxióng; May 31, 1912 – February 16, 1997) was a Chinese American experimental physicist who made significant contributions in the field of nuclear physics. Wu worked on the Manhattan Project, where she helped develop the process for separating uranium metal into uranium-235 and uranium-238 isotopes by gaseous diffusion. She is best known for conducting the Wu experiment, which contradicted the hypothetical law of conservation of parity. This discovery resulted in her colleagues Tsung-Dao Lee and Chen-Ning Yang winning the 1957 Nobel Prize in physics, and also earned Wu the inaugural Wolf Prize in Physics in 1978. Her expertise in experimental physics evoked comparisons to Marie Curie. Her nicknames include "the First Lady of Physics", "the Chinese Madame Curie", and the "Queen of Nuclear Research".[1]

In March 1944, Wu joined the Manhattan Project's Substitute Alloy Materials (SAM) Laboratories at Columbia University. She lived in dormitory there, returning to Princeton on the weekends.[27] The role of the SAM Laboratories, headed by Harold Urey, was to support the Manhattan Project's gaseous diffusion (K-25) program for uranium enrichment. Wu worked alongside James Rainwater in a group led by William W. Havens, Jr.,[28] whose task was to develop radiation detector instrumentation.[21]
In September 1944, Wu was contacted by the Manhattan District Engineer, Colonel Kenneth Nichols. The newly commissioned B Reactor at the Hanford Site had run into an unexpected problem, starting up and shutting down at regular intervals. John Archibald Wheeler suspected that a fission product, xenon-135, with a half-life of 9.4 hours, was the culprit, and might be a neutron poison. Segrè then remembered the work that Wu had done at Berkeley on the radioactive isotopes of xenon. The paper on the subject was still unpublished, but Wu and Nichols went to her dorm room, and collected the typewritten draft prepared for the Physical Review. Xenon-135 was indeed the culprit; it turned out to have an unexpectedly large neutron absorption cross-section.[28]
