Xu Guangxian (simplified Chinese: 徐光宪; traditional Chinese: 徐光憲; pinyin: Xú Guāngxiàn; November 7, 1920 – April 28, 2015) was a Chinese academician of the Chinese Academy of Science. He is a former president of the Chinese Chemical Society, and is known as "The Father of Chinese Rare Earths Chemistry".
Xu was born in Shaoxing, Zhejiang in 1920. He studied in Zhejiang (now known as Zhejiang University and Zhejiang University of Technology), before entering Jiaotong University in Shanghai (now known as Shanghai Jiaotong University) and received his B.S in 1944. From 1944 to 1946, he served as a technician at a chemical company in Shanghai.
Xu traveled to the US in 1948, where he attended the graduate school of the Washington University in St. Louis. From 1948 to 1951, he studied at Columbia University in New York City and received his MS in 1949 and his PhD in 1951 (under C. D. Beckmann). In February 1949, he became a member of the National Honorary Chemical Society's Phi Lambda Upsilon. In October 1950, Guangxian became a member of Sigma Xi.
Guangxian went back to China in 1951 where, in the same year, he became an associate professor at the Department of Chemistry, Peking University, but was soon promoted to a full professor. He became the department dean in 1956 and directed the department of radiation chemistry. Xu was also involved in the Chinese nuclear weapons development program, in which he played a role in separating and extracting nuclear elements, especially Uranium-235.
