**Loo-Keng Hua**

Loo-Keng Hua, was born in Jintan county, Jiangsu Province on November 12, 1910, died in Tokyo, Japan on June 12, 1985. After graduation from Jintan Junior Middle School in 1924, he studied at Shanghai Chung-Hua Vocational School, Shanghai for less than 2 years before dropping out of school because of poverty. Since then he has been taught himself mathematics diligently, which brought C. L. Hsiung’s attention. He was invited to teach at Tsinghua University in 1931. He continued studying mathematics while working at Tsinghua, he was promoted as assistant lecturer by exception in 1933, became a lecturer in 1935. Hua visited Cambridge University in England in 1936 supported by Tsinghua. He returned in 1938, employed as a professor at Tsinghua University. Hua was invited to do research at Institute for Advanced Study at Princeton, USA in 1946, served as a professor at University of Illinois in 1948. Then he returned to Tsinghua as a professor. In 1952, Institute of Mathematics, Chinese Academy of Sciences was founded at Tsinghua University. Hua was the director. Hua was nominated as an academician of Chinese academy of Sciences in 1955. In the following years, He served as director of Institute of Mathematics, Chinese Academy of Sciences, member of the math- physics-chemistry department and vice director of education department, chair of math department and Vice President of University of Science & Technology of China, director of Institute of Applied Mathematics, Chinese Academy of Sciences, vice president of Chinese Academy of Sciences, committee member of chairman group, etc. He also served as member of the National People's Congress Standing Committee and Vice chairman of the National Committee of the Chinese People's Political Consultative Conference (CPPCC).

Hua was one of the leading mathematicians in 20th century. His research field involves function of several complex variables, number theory, algebra and applied mathematics and many other aspects, all of which have great impact on mathematics. He had great success on every aspect. There are many theorem, lemma, inequality, operators and methods named after him, such as the Hua’s Lemma in number theory (full triangle and estimates), Hua’s inequality, the semi-automorphism theorem in edgebra, and research of several complex function on the four categories of typical domain and the introduction of Hua operators and the high dimensional quadrature formulas of the cyclotomic field in the numerical calculation and so on. He had a group of outstanding students. He won the first prize of National Nature Science Award in 1956. In 1990, together with Yuan Wang, he won CHEN Jiageng Science award. He was elected foreign fellow of the American Science Academy, academician of Third World Academy of Sciences, academician of Germany Bavarian Academy of Sciences. He was awarded honorary doctorate by the Nancy University of France, Hong Kong Chinese University and the University of Illinois. He has published 163 papers in mathematics, 13 mathematical monographs, 10 math science books.

In 2002, National Academy of Sciences published “Loo-Keng Hua”.

华罗庚，1910年11月12日生于江苏省金坛县，1985年6月12日在日本东京逝世。1924年初中毕业后，在上海中华职业学校学习不到两年，因家贫缀学，而刻苦自修数学，受到熊庆来的重视，于1931年被邀请到清华大学工作。华罗庚在清华大学一面工作，一面学习，于1933年被破格提升为助教，1935年成为讲师，1936年他经清华大学推荐，访问英国剑桥大学。1938年回国，受聘为清华大学教授。1946年应美国普林斯顿高等研究院邀请任研究员，1948年担任伊利诺伊大学教授。1950年回国，任清华大学教授。1952年中国科学院数学研究所在清华园正式成立，华罗庚任所长。于1955年当选为中国科学院院士。此后，他先后担任中国科学院数学研究所所长、数理化学部委员和学部副主任、中国科技大学数学系主任和副校长、中国科学院应用数学研究所所长、中国科学院副院长、主席团委员等职，还担任过全国人大常委会委员和全国政协副主席。

华罗庚是20世纪领导数学家之一，他的研究领域涉及多元复变数函数、数论、代数及应用数学等许多方面，对数学有普遍的影响。在每一个领域都取得了杰出的成果，有许多以他的名字命名的定理、引理、不等式、算子与方法，例如数论中的华氏引理（完整三角和估计），华氏不等式，代数中的半自构定理，多复变函数论中对四类典型域的研究与华算子的引入及数值计算中的分圆域高维求积公式等。他并培养了一批优秀的学生。1956年获得国家自然科学奖一等奖，1990年与王元共获陈嘉庚物质科学奖。他被选为美国科学院国外院士、第三世界科学院院士、联邦德国巴伐利亚科学院院士，被法国南锡大学、香港中文大学与美国伊利诺伊大学授予荣誉博士学位。先后发表过数学论文163篇，出版13部数学专著，10本数学科普著作。2002年美国科学院出版了华罗庚传.
