- Early Life and Education: Born in Liuhe, Taicang, Jiangsu province, China, Wu received her undergraduate degree from National Central University in Nanjing. She later moved to the United States to pursue graduate studies, earning her Ph.D. in physics from the University of California, Berkeley, in 1940.
- Scientific Contributions: Wu’s most famous achievement is the “Wu experiment,” which experimentally confirmed the theory of parity non-conservation in weak interactions, proposed by Tsung-Dao Lee and Chen-Ning Yang. This groundbreaking work challenged a long-held principle in physics and led to Lee and Yang receiving the Nobel Prize in Physics in 1957; however, Wu’s crucial experimental contribution was notably overlooked by the Nobel committee.
- Career and Recognition: She held positions at Princeton University and Columbia University, where she became a full professor. Wu received numerous accolades throughout her career, including the first Wolf Prize in Physics in 1978 and becoming the first woman elected president of the American Physical Society in 1975. She was also a strong advocate for women in science.
- Later Life: Wu retired from Columbia University in 1981 and continued to be an inspirational figure, promoting dedication and determination in scientific pursuits. She passed away in New York City in 1997.
