吴健雄 (Chien-Shiung Wu) (1912–97) - A female Chinese-American physicist who worked on the Manhattan Project. She helped to develop the process for separating uranium metal into the U-235 and U-238 isotopes by gaseous diffusion. Wu’s work verified a hypothesis put forth in 1956 by her Columbia colleague Tsung-Dao Lee and Chen-Ning Yang that, unlike all other known physical forces, the “weak” interactions among decaying particles are not always symmetrical in nature. Wu contributions to research brought her many awards, including the National Medal of Science in 1975, the first Wolf Prize in Physics in 1978, and Columbia’s Pupin Medal in 1991. In 1973, she was became the first woman to head the American Physical Society, and she was also the first living scientist to have an asteroid named after her.
