Amadeus W. Grabau (1870-1946) was not only a world famous geologist, paleontologist, but also took a very active part in geological education in China during the first half of the 20th century. Invited by Dr. V. K. Ting丁文江, Grabau came to China from Columbia University in 1920 and acted concurrently as chief paleontologist of the Geological Survey of China and professor at the National Peking University. He not only devoted himself to scientific research but also trained many Chinese students with enthusiasm. The first generation of Chinese geologists and paleontologists, such as Sun Yunzhu 孙云铸, Yang Zhongjian杨钟健, Gao Zhenxi高振西, Zhao Yazeng赵亚曾, Tian Qijun田奇隽, Si Xingjian斯行健, Huang Jiqing黄汲清, Zhang Xiti张席褆, Yue Senxun乐森璕, Zhu Sen朱森, Xu Jie许杰, Ji Rongsen计荣森, were all directly influenced by him. Through his popular reports, lectures, and correspondence, he also helped promote the development of Chinese geology to the public in both China and the West. In short, Grabau made indispensable contributions to the development of Chinese geological science, which he hoped would take a place in the world. There are some studies of Grabau, but none of them has made in-depth investigation about his role in Chinese geological education. This paper will discuss Grabau’s influence on Chinese geological education during the first half of the 20th century. I will examine his works, particularly those concerning Chinese geological and paleontological studies and investigate his role in training Chinese students and organizing geological societies based on both Chinese and Western sources, especially the primary materials at Peking University Archives and the Second Historical Archives of China as well as the memoirs of his pupils and colleagues.
