1950年6月，新中国的科学院建立不久，在百废待兴的情形下，着手筹建数学研究所。筹备处设在北京文津街3号，由著名数学家苏步青任筹备处主任，周培源、江泽函、华罗庚、许宝騄任筹备处副主任，田方增任秘书。筹建工作受到中央人民政府的高度重视。1951年1月，政务院批文任命华罗庚为即将成立的数学研究所所长。1952年7月1日数学研究所正式成立，所址设在清华园内，确立了纯粹数学与应用数学协同发展的方针。最早成立的研究小组有数论、微分方程、力学、计算机研制、概率统计、代数、拓扑学等。
1953年上半年，数学研究所共有科研人员32人，其中专任研究员5人。仅在这32人中，后来当选为中国科学院院士的就有17人。
(1)Founding
In June 1950, the Institute of Mathematics was under preparation soon after the Chinese Academy of Sciences (CAS) was founded, and many things were waiting to be done. The preparation office was located at No.3 Wenjin Street in Beijing. The well-known mathematician Su Buqing was the director, Zhou Peiyuan, Jiang Zehan, Hua Luogeng and Xu Baolu were the deputy directors of the office, and Tian Fangzeng was the secretary. The central government of the country attached great importance to the founding of the institute. In January 1951, the State Council approved the appointment of Hua Luogeng as the director of the Institute of Mathematics to be founded. In July 1, 1952, the institute was established and located on the campus of Tsinghua University. The institute decided to focus its research on coordinated development of pure mathematics and applied mathematics. The first research groups were set up to study number theory, differential equations, mechanics, computer development, probability and statistics, algebra, and topology.
In the first half of 1953, there were 32 researchers in the institute, including 5 research professors (Hua Luogeng, Min Naida, Wu Xinmou, Zhang Sucheng, Wu Wenjun), 5 associate research professors (Guan Zhaozhi, Tian Fangzeng, Wang Shouren, Zhuang Fenggan, Xia Peisu), 6 assistant research professors (Lin Hongsun, Sun Yifeng, Yue Minyi, Feng Kang, Wan Zhexian, Hu Haichang), 11 research trainees (Lu Qikeng, Gong Sheng, Hu Hesheng, Zhang Liqian, Wang Guangyin, Qiu Peizhang, Ding Xiaqi, Xu Kongshi, He Shanyu, Sun Hesheng, Wang Yuan), and 5 joint research professors (Su Buqing, Chen Jiangong, Duan Xuefu, Hu Shihua, Zhang Zongsui). The directions they started laid foundations for the development of the institute. Only among those 32 people, 17 were elected academicians (Members) of the CAS.
