  The years 1910-1911 are auspicious years in Chinese mathematics with the
births of Pao-Lu Hsu, Luo-Keng Hua and Shiing-Shen Chern. These three began the
development of modern mathematics in China: Hsu in probability and statistics,
Hua in number theory, and Chern in differential geometry. We here review some
facts about the life of P.-L. Hsu which have been uncovered recently, and then
discuss some of his contributions. We have drawn heavily on three papers in the
1979 Annals of Statistics (volume 7, pages 467-483) by T. W. Anderson, K. L.
Chung and E. L. Lehmann, as well as an article by Jiang Ze-Han and Duan Xue-Fu
in Hsu's collected papers.
