Chia-Shun Yih

Yih was born on July 25, 1918 in Guiyang, Guizhou province of China. Yih received his junior middle school education in Zhenjiang, and entered Suzhou High School in 1934 in Suzhou, Jiangsu Province.

In 1937 Yih entered the National Central University (After 1949 named Nanjing University in Jiangsu of P.R.China; after 1952, its engineering faculty formed the Southeast University also in Nanjing) and studied civil engineering. Yih graduated in 1941 then did research at a hydrodynamics laboratory in Guanxian (or Guan County; 灌县; current Dujiangyan) of Sichuan province. Yih also worked in a bridge construction company in Guizhou. Later, Yih taught at Guizhou University.

In 1945 Yih went to study at the University of Iowa in the United States, where he obtained his PhD in 1948. Yih served as a professor of the University of Michigan for most of his academic career.

Yih is also well known for his high language talent, which appeared already when he was just a high school student. In his first classes in high school, he could talk fluently with his American English teacher. Yih mastered German soon after he joined the college, and was able to communicate smoothly with the local German missionaries in Chongqing. Later Yih again learned French, and lectured mechanics in French at the University of Paris and the University of Grenoble.

He died on April 25, 1997 of heart failure, in his sleep, while in an airplane over Japan.[3]
