Hu Xiansu

Hu Xiansu or Hu Hsen-Hsu (24 May 1894 – 16 July 1968), courtesy name Buzeng, art name Chan'an, was a Chinese botanist and polymath. He was the founder of modern botany in China, and a pioneer of paleobotany in the country. His most notable scientific achievement was the identification of the living fossil Metasequoia glyptostroboides (dawn redwood) in 1948, widely considered as one of the greatest botanical discoveries of the 20th century. Outside botany, Hu also made significant contributions in the field of literary criticism and education. In 1922, in opposition to the New Culture Movement, he co-founded The Critical Review (Xueheng), a major Chinese-language journal which advocated the preservation of classical Chinese literature. He also led the Xueheng School. From 1940 to 1944, he served as the inaugural president of National Chung Cheng University, which is now primarily Jiangxi Normal University. Targeted as an intellectual during the Cultural Revolution, he endured repeated struggle sessions, the harm and stress of which likely contributed to his fatal heart attack in Beijing on 16 July 1968. The standard author abbreviation Hu is used to indicate this person as the author when citing a botanical name.

Early life Hu Xiansu was born on 24 May 1894 (20th of the fourth month in the lunar calendar) in Nanchang, Jiangxi, to Hu Chengbi and Chen Caizhi into a family with a lineage of scholar-officials. Hu's great-grandfather Hu Jiayu was an influential high-official in the Qing Court. Hu Xiansu was given the courtesy name of Buzeng ('Following the steps of great-grandfather') by his father, indicated his family's desire for Hu to emulate his great-grandfather's success; but by then, the large family was already in decline. After Hu's father died when he was eight, his family fell into further financial difficulties. Considered a prodigy, Hu read the Three Character Classic and the Thousand Character Classic at the age of three, and knew thousands of characters; at four, he started to learn the Analects and knew more than ten thousand characters. The early education of Confucian classics and traditional literature deeply shaped Hu's lifelong view on the value of literature and morals.

Education Hu attempted his first imperial examination in 1904 at age 10, but the examination was abolished soon after in 1905. Hu went to the Hongdu Middle School in Nanchang in 1906 to start his modern education. Hu studied a preparatory course at the Imperial University of Peking (now Peking University) in 1909. In October 1911, the Xinhai Revolution overthrew the Qing dynasty, discontinuing the operations of the university and ending Hu's studies there. Hu went to the United States in December 1912 and enrolled in the University of California (now University of California, Berkeley). During his years in Berkeley, Hu became an active member of the newly founded Science Society of China and joined the editorial board of the Society's journal Science. At the same time, Hu read English literature extensively. In 1914, Hu began to correspond with fellow Peking University alumni Hu Shih, developing a lifelong friendship. In May 1916, Hu graduated with honours in botany and became members of the honour societies of Sigma Xi and Phi Beta Kappa. In 1918, he became a faculty member of Nanking Higher Teacher's School (now mainly Nanjing University). Hu went to the United States again in 1923 and studied in Arnold Arboretum of Harvard University, receiving his doctorate in 1925. His doctoral dissertation, under the supervision of dendrologist John George Jack, was the first comprehensive survey of plants in the whole of China.

Career In 1920 and 1921, Hu conducted large-scale plant collections in Zhejiang, Jiangxi and Fujian. In 1921, Hu and zoologist Ping Chih founded the Department of Biology in the National Southeast University, the first biology department in Chinese public universities. In 1922, Hu, Ping, and Yang Xingfo founded the Institute of Biology of the Science Society of China, the first biological research institute in China; he became a full-time research fellow at the institute in 1926, after resigning from the National Southeast University. In 1923, Hu along with colleagues Zou Bingwen and Sung Shu Chien published the college-level textbook Advanced Botany, the first such textbook compiled by Chinese scholars. It became widely used in universities around China. In 1928, Hu moved to Beijing and co-founded the Fan Memorial Institute of Biology. The Fan Institute was named after Fan Yuan-Lien, an important educator and philanthropist. With long-term financial support from the China Foundation for the Promotion of Education and Culture, the Fan Institute developed into a major scientific institute in China. Hu directed the botanical branch of the Fan Institute and from 1932 served as the director of the Institute until 1949. Meanwhile, he taught part-time in the biology departments of Peking University and Beijing Normal University. In 1933, Hu played a leading role in the founding of the Botanical Society of China, serving as its second president. In 1934, Hu founded the Lushan Forest Botanical Garden in Jiujiang, Jiangxi. Through Hu's influence, the Lushan Forest Botanical Garden established wide exchange networks with botanical gardens and research institutes around the world. In 1936, fearing for the likelihood of a potential outbreak of war in northern China, Hu established the Yunnan Institute of Agriculture and Forest in southwestern China. Between 1938 and 1940, Hu co-authored The Miocene Flora of Shandong Province, China with Ralph W. Chaney; it was the first work investigating China's Cenozoic fossil plants, and is considered the cornerstone of current knowledge of Asian Cenozoic plants. Between 1940 and 1944, he served as the inaugural president (chancellor) of the National Chung Cheng University, now primarily Jiangxi Normal University, with both Nanchang University and Jiangxi Agricultural University claiming partial heritage.

Taxonomic naming Over his career, Hu published 2 new families, 17 new genus, and 408 new species of modern plants, and 87 new species of fossil plants. Notably, the genus Sinojackia published in 1928, which was named after Hu's Harvard advisor John George Jack, was the first genus ever described by a Chinese botanist. Similarly, the new family Torricelliaceae, published in 1934, was the first new plant family described by a Chinese botanist.
