Chien-Shiung Wu
From 1946 to 1956, he was associated with the Cryogenic Laboratory of Columbia University where he collaborated with Henry A. Boorse, an expert on low-temperature physics, on the measurement of heat capacities of superconducting metals and other researches. During this time he was involved in helping Chien-Shiung Wu to arrange for her groundbreaking experiment, in which the violation of parity conservation in weak interactions was established, to be carried out at the low-temperature laboratories of the National Bureau of Standards.
