Chien-Shiung (健雄) means "strong hero" — a deliberately gender-neutral name chosen by her progressive father. **Chien-Shiung Wu (1912-1997)** was the **Chinese-American experimental physicist** whose 1956 **"Wu experiment" disproved the law of parity conservation** in physics — leading to the 1957 Nobel Prize for her male collaborators Lee and Yang (Wu was controversially passed over). **Worked on the Manhattan Project**, called "the First Lady of Physics" and "the Chinese Madame Curie."
**Honored on a 2021 U.S. postage stamp.**
Chien-Shiung reduces to three — the number of First Lady of Physics.
