Chien-Shiung Wu
Lawrence offered Segrè a job as a research assistant—a relatively lowly position for someone who had discovered an element—for US$300 a month for six months. However, when Lawrence learned that Segrè was legally trapped in California, he reduced Segrè's salary to US$116 a month. When the regents of the University of California wanted to terminate Segrè's employment owing to his foreign nationality, Lawrence managed to retain Segrè by hiring him as a part-time lecturer paid by the Rockefeller Foundation. Similar arrangements were made to retain his doctoral students Chien-Shiung Wu (a Chinese national) and Kenneth Ross MacKenzie (a Canadian national) when they graduated.
