Immanuel C. Y. Hsu

Immanuel Chung-Yueh Hsü (1923 – October 24, 2005, 徐中約; pinyin; Xú Zhōngyuē) was a sinologist, a scholar of modern Chinese intellectual and diplomatic history, and a professor of history at the University of California at Santa Barbara.

Born in Shanghai in 1923, he studied at Yenching University in Beijing, and at the University of Minnesota. He held a Harvard-Yenching Fellowship at Harvard University from 1950 to 1954. After receiving his doctorate from Harvard, he spent the years 1955–1958 as a Research Fellow at Harvard's East Asian Research Center. He taught modern Chinese history at the University of California at Santa Barbara from 1959 until his retirement in 1991, serving as Chair of the History department from 1970 to 1972. He was a Guggenheim Fellow in 1962–1963, as well as a Fulbright Fellow. His most widely read book is The Rise of Modern China, a survey of Chinese history from 1600 to the present, and a standard textbook.

He died of complications from pneumonia on October 24, 2005.

According to Jonathan Spence in the Preface to the Chinese translation of his The Search for Modern China, the "two most prominent previous (to The Search for Modern China) English-language surveys" (of modern Chinese history) were those "by John King Fairbank in the 1960s and by Immanuel Hsu in the 1970s". Spence acknowledged that he had learned much from these two scholars.
