Model 107, the first general-purpose electronic computer designed entirely within the People's Republic of China, became operational in 1960 under the technical leadership of Xia Peisu. Her transition from academic research into practical engineering established the foundations for the nation’s computing infrastructure, eventually earning her the reputation as a central figure in the development of Chinese computer science.
Academic Foundation and International Training
Born in 1923 in Chongqing, Xia received early instruction in prose and mathematics through her family. She pursued formal education in electrical engineering, graduating from the National Central University before moving to postgraduate studies at the Telecommunications Research Institute of National Chiao Tung University. In 1947, she enrolled at the University of Edinburgh, completing her PhD in 1950 with a dissertation focusing on parametric oscillations in electronic circuits and graphical analysis for non-linear systems.

Upon returning to China in 1951, Xia joined the Department of Electrical Engineering at Tsinghua University. By 1952, she was recruited by the Chinese Academy of Sciences to assist mathematician Hua Luogeng. Following the departure of her initial project partners, she spearheaded the Model 107 project. Beyond this hardware achievement, she authored the country's first systematic computer science textbook, Principles of the Electronic Computer, and inaugurated the first academic course on computer theory in March 1956.
Institutional Influence and Legacy
Xia played an integral role in institutionalizing the field, overseeing the establishment of the computer science department at the University of Science and Technology of China in 1958. Throughout her tenure, she instructed over 700 students and advised more than 60 graduate researchers. Her professional contributions extended to academic publishing, where she helped launch the Chinese Journal of Computers in 1978 and the Journal of Computer Science and Technology in 1986.
Honours and Professional Recognition
In 1991, Xia was elected as an academician of the Chinese Academy of Sciences, a distinction she shared with her husband, theoretical physicist Yang Liming. Her career was further marked by the inaugural Lifetime Achievement Award from the China Computer Federation in 2010. Following her death in Beijing in 2014, the federation established an annual award in her name to recognize female scientists and engineers for their contributions to the industry.
