李政道
[[Chien-Shiung Wu]] disproved the law of the [[parity (physics)|conservation of parity]] (1956) and was the first [[Wolf Prize]] winner in physics. She died in 1997 without receiving a Nobel. Wu assisted [[Tsung-Dao Lee]] personally in his parity laws development—with [[Chen-Ning Yang]]—by providing him in 1956 with a possible test method for beta decay that worked successfully. Her book "Beta Decay" (1965) is still a [[sine qua non]] reference for nuclear physicists.
