Dauben This dissertation presents a research that relied on the online Archive of the Grand Secretariat at the Institute of History of Philology of the Academia Sinica in Taiwan and many digitized archival materials to reconstruct the hereditary mathematician families of the Astronomical Bureau in Qing China. The research found several patterns and strategies that these hereditary mathematician families exhibited during their long careers at the Astronomical Bureau. It found that family networks remained the most important channel that the Astronomical Bureau used to recruit new members until the last days of the Qing dynasty. Moreover, professional mathematicians at the Astronomical Bureau were willing to learn new knowledge—including switching from the Chinese traditional Great Concordance system of calendar making to the New Western Method introduced by European Jesuit mathematicians— and continue sending their descendants to work for the Astronomical Bureau as long as their families were properly rewarded. This dissertation chooses the family of He Guozong, one of the most famous mathematicians of the early Qing period, as its representative case, because of the richness of the records related to the He family and the roles it played in several important junctures of the v history of the Astronomical Bureau. Familial connection became a cause of the stagnation of the Astronomical Bureau in the late eighteen century. However, the dissertation uses the case study of superintendent Jingzheng and the hereditary mathematician families in the first half of the nineteenth century to show that a capable administrator and a strictly implemented periodical examination system had effectively stimulated competition among mathematician families and ousted the old and incompetent ones, such as the He family. vi Acknowledgements I would like to express my sincerest thanks and gratitude to Professor Joseph Dauben, who had taught me not just the methods but also the joy of historical research. Without his patience and encouragement, my journey to earning a PhD would not come to a happy conclusion. I also wish to express my appreciation to the other members of my dissertation committee, Professors Richard Lufrano, David Gordon, and Wann-Sheng Horng. Thanks for reading my dissertation and giving me invaluable advices. To all my friends: Jessie, Cj Chiang, SC Wang, Maylin, TzuChen, Vickie, Huailo and many others, thank you for keeping my spirits high and giving me so many helps to my life. vii DEDICATED TO MY PARENTS, TSANG-LANG CHANG and EMMY CHOU CHANG viii CONTENTS ABSTRACT . iv ACKNOWLEDGEMENTS . vi LIST OF TABLES . xi LIST OF FIGURES . xii REIGN TITLES OF THE QING EMPERORS (1644–1911) . xiii Chapter 1.

An audience such as this represented the only occasion for lower-ranking civil servants like Bao to communicate directly with the emperor.1 At the time, Bao was forty-six years old and had worked at the Astronomical Bureau all of his adult life.2 Three years earlier he had been promoted to one of the highest positions in the Calendar Section 曆科 and had been in charge of calculating the official calendar for the dynasty. As a result of his long and excellent service record, Bao was granted a new position as a second-class secretary 主事 at the Ministry of Works 工部. However, while the other officials at this imperial audience hoped to be approved for new jobs, Bao’s object was to convince the emperor to let him remain in his old post. Uncertain about how much time he would be allowed to talk to the emperor, Bao Qinhui elaborated his concerns in the résumé that the emperor would be browsing through during the audience. Bao began by recounting his familial lineage: 1 In the Qing dynasty, the civil service ranking hierarchy was divided into nine levels.
