Zhi Bingyi

On 24 July 1993, he died of illness in Shanghai, aged 81.

In 1951, he founded the Yellow River Science and Technology Instrument Factory (黄河理工仪器厂), which was merged into Shanghai Electric Meter Factory (上海电表厂) in 1954. After the institutional reform, he served as deputy chief engineer and director of central laboratory. In 1957, he engaged in the research on aging treatment of manganin resistance elements and solved the quality problem of domestic manganin. He also participated in the development of the first 5-bit DC digital voltmeter in China in the 1960s. In 1964, he was transferred to the Shanghai Institute of Electrical Instruments (上海电工仪器研究所; later reshuffled as Shanghai Instrument Research Institute 上海仪器仪表研究所), where he successively served as chief engineer, deputy director, director, and honorary director. In 1966, the Cultural Revolution broke out, two years later, he was denounced as a "reactionary academic authority" and suffered political persecution. During that time, he "worked on his ideas about a Chinese computer language in a squalid prison cell during the Cultural Revolution, writing his calculations on a teacup after his guards took away even his toilet paper." In September 1969, he was released from an isolation room. He was supervised to sweep the floor, clean the lathe, and then worked as a waste warehouse keeper. In his spare time, he used six years to invent the coding method of Jian Zi Shi Ma (见字识码; 'On-Sight Coding'), which made a great contribution to Chinese character coding and Chinese character information processing. He joined the Communist Party in May 1991.

He returned to China in 1946 and that same year was recruited by the Central Industrial Laboratory (中央工业试验所) as an engineer, as well as director of electronic laboratory. From 1947 to 1951, he was professor at Zhejiang University, Tongji University and Shanghai Aviation College.

Zhi Bingyi (Chinese: 支秉彝; pinyin: Zhī Bǐngyí; 19 September 1911 – 24 July 1993) was a Chinese scientist in the fields of telecommunications engineering, measuring instrument and Chinese character encoding. He was one of the earliest figures in Chinese history to have contributed to the science of characters computer processing. He has been hailed by many as "Chinese characters information processing pioneer". He was an academician of the Chinese Academy of Sciences.

Zhi was born into a highly educated family in Taizhou County, Jiangsu, on 19 September 1911, while ancestral home in Zhenjiang. He secondary studied at Taizhou High School. In 1931, he was accepted to Zhejiang University, where he majored in the Department of Electrical Engineering. In 1934, he pursued advanced studies in Germany, earning a doctor's degree in natural science from Leipzig University in 1944.
