Abstract: Hu Chien-shan is a famous expert on vibration and educator on engineering mechanics. He graduat-ed from physics department of Tsinghua University in 1933, and he went to University of London to make cosmic rays research in 1934. After he received a doctor＇s degree in 1937, he retuned back. He engaged in mechanical engineering research and education of engineering mechanics since 1944, and he made great contribution to the de- velopment of mechanics of Southeast Uniersity. This paper analyzes Hu＇s research on cosmic rays, mechanics, and his education contribution, also analyzes in-depth Hu＇s academic achievements and characteristics in education. This work provieds historical materials for modern physics history through digging Hu＇s life experience and academic work so that learn noble qualites from Hu Chien-shan and memory of him.
