Shiing-Shen Chern (October 28, 1911-December 3, 2004) was born in Jiaxing, Zhejiang Province, China. He received his Bachelor Degree from Nankai University in 1930, Master's Degree from Tsinghua University in 1934 and Doctoral Degree from Hamburg University in 1936. After this, he went to Paris to pursue his research career. During the years of 1937-1943, he was a professor at Tsinghua University and Southwest Associated University. From 1943-1946, he was a researcher at the Institute for Advanced Study (IAS) at Princeton, USA where he achieved great creative advances in the field of Differential Geometry and Topology. In 1946-1948, he began preparations to found the Academia Sinica in Nanjing and he was its deputy director. In 1948, he was elected as an academician of Academia Sinica. From 1949-1960, he assumed the post of professor at Chicago University, and from 1960-1979 at University of California, Berkeley. From 1981-1984, he was the first director of Mathematical Sciences Research Institute (MSRI). Since 1972, Mr. Chern had visited and lectured in China many times. In 1985, he founded the Nankai Institute of Mathematics and was its first director. In 2002, he helped to bring about the holding of the International Congress of Mathematicians (ICM) to Beijing and was elected as the honorary president of the conference. In 2000, the Tianjin People’s Government conferred on him the Perpetual Residence Right. Mr. Chern was an academician of U.S. National Academy of Sciences, and foreign academician and member of many other countries’ Academies of Sciences or Royal Societies, such as China, France, Italy, Russia, Britain, etc. He was awarded many honors, such as the U.S. National Medal of Science, the Wolf Prize from the Israeli government, the Humboldt Prize from Germany, China’s International Scientific and Technological Cooperation Prize, the first Shaw Prize in Mathematics, etc. Due to his outstanding contributions and deep influence in global Differential Geometry community, Mr. Chern is recognized as a “Great Geometer of the Twentieth Century”.

Chih-Ta Yen  was born on November 1, 1917, in Nantong, Jiangsu. He graduated from the Department of Mathematics of Southwest Associated University in 1941, received his Ph.D. degree from the Université de Strasbourg in 1949, and returned to China in 1952. He served as a professor at the Department of Mathematics of Nankai University and a professor at the Nankai Institute of Mathematics. He was elected a member of the Chinese Academy of Sciences in 1993. He died of illness on April 30, 1999.

Chih-Ta Yen is mainly engaged in the research of Lie groups, Lie algebras, differential geometry, and gear meshing theory. During his college years, he, joint with Professor S. S. Chern, published a paper on a basic formula of motions in integral geometry, which was called “Chern-Yen formula” and is still widely used today. He was the first mathematician in the world to calculate Betti numbers of special simple Lie groups. With his efforts, a series of achievements have been obtained on the study of real semi-simple Lie groups, Lie algebras, and symmetric space theory. Yen’s new method on the classification of real semi-simple Lie algebras greatly simplified the relevant work of famous French mathematician Cartan, and satisfactorily solved the classification problem of the non-compact symmetric spaces proposed by Cartan. He also applied the theory of differential geometry to gear meshing theory, expounded many important concepts, and deduced the "induced curvature formula", which has promoted the development of China’s machinery industry.

He also served as a member of the 3rd and 4th Councils of the Chinese Mathematical Society, and a representative of the 10th and 11th People’s Congress of Tianjin (1983-1993).
