What citizenship did Chen Jiangong hold from 1910 to 1911?
Chen Jiangong Chen Jiangong ( ; 1893–1971 ) , or Jian-gong Chen , was a Chinese mathematician . He was a pioneer of modern Chinese mathematics . He was the dean of the Department of Mathematics , National Chekiang University ( now Zhejiang University ) , and a founding academician the Chinese Academy of Sciences ( elected 1955 ) . Life . Chen was born in Shanyin County ( now Shaoxing ) , Zhejiang Province during the late Qing dynasty . He studied at Shanyin School and later Shaoxing Prefecture School . In 1910 he entered the Zhejiang Advanced Normal School , a teacher-training institution which was later merged into National Chekiang University . Chen later went to Japan to continue his studies . In 1916 he graduated from the Tokyo Institute of Technology , where he majored in textile technology , and the Tokyo Academy of Physics ( now known as the Tokyo University of Science ) . After graduating from Tohoku Imperial University in 1923 , Chen returned to China and became a lecturer at the Zhejiang Industrial School , which was later merged into National Chekiang University . In 1924 he went to Wuhan , Hubei Province , and became a professor at National Wuchang University ( now Wuhan University ) . In 1926 , Chen returned to Tohoku Imperial University to continue his studies in mathematics , completing his Ph.D . in 1929 and becoming the first international student awarded a Ph.D . by a Japanese university . It was during this time that he met his later colleague Su Buqing , a fellow mathematics Ph.D . candidate . After earning his doctorate , Chen was offered teaching positions at institutions including Peking University and Wuhan University . However , on the invitation of National Chekiang University president Shao Feizhi , Chen returned to Zhejiang University to serve as dean of the Department of Mathematics , a position he held for the next 20 years . After earning his doctorate in 1931 , Su Buqing was invited to join Chens department and take over his position as department chair , allowing Chen to focus more on research . Their collaboration resulted in the Chen-Su school of mathematics in Hangzhou . The outbreak of the Second Sino-Japanese War in 1937 forced Chen , and much of Zhejiang University , to relocate from Hangzhou . In February 1940 , Chen arrived at Zunyi , and then subsequently Meitan , Guizhou Province , where he helped re-establish the colleges of engineering and sciences . In 1945 , after the end of the Second Sino-Japanese War , Chen was invited by biologist Luo Zongluo ( Lo Tsung-lo ) , who was serving as the 1st president of National Taiwan University ( formerly Taihoku Imperial University ) , as well as the Nationalist government in Nanjing , to travel to Taipei and serve as acting dean of NTU during its reorganization . In the spring of 1946 , Chen returned to mainland China ( then still controlled by Nationalist government ) , where he continued teaching in National Chekiang University and became a researcher in the Mathematics Research Institute at the Academia Sinica . From 1947 to 1948 , Chen traveled to the United States to do research at the Institute for Advanced Study at Princeton University . He was elected an academician of the Academia Sinica in 1948 . After the Chinese Civil War , Chen remained in Zhejiang , now part of the Peoples Republic of China . In 1952 , Zhejiang University was dissociated and its colleges of sciences and humanities were merged with Fudan University in Shanghai . Both Chen and Su Buqing moved to Fudan University , where they continued their cooperation and the Chen-Su school of mathematics . While in Shanghai , Chen translated many mathematical works produced in the USSR . In recognition of his advancements in the field of mathematics , in 1955 Chen was elected an academician of the Chinese Academy of Sciences in its inaugural year . In 1958 , some departments of Zhejiang University were split from the university in order to form Hangzhou University ( which eventually merged back into Zhejiang University in 1998 ) . Chen was appointed to vice president of Hangzhou University and moved back to Hangzhou .
