Zhi Bingyi

Zhi Bingyi (; 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.

Biography

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.

He returned to China in 1946 and that same year was recruited by the Central Industrial Laboratory () 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.

In 1951, he founded the Yellow River Science and Technology Instrument Factory (), which was merged into Shanghai Electric Meter Factory () 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 (; later reshuffled as Shanghai Instrument Research Institute ), 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'' (), which made a great contribution to Chinese character coding and Chinese character information processing.

Zhi wished for an intuitive but unique alphabetic code for Chinese characters. Zhi's predecessors, i.e., Bismarck Doo, Wang Yunwu, and Lin Yutang preferred a shape-based approach to encoding, examining a character's strokes and components and grouping them into categories. However, the official adoption of pinyin made the phonetic approach a national policy. Zhi was able to combine pinyin and a shape-based approach to index characters by their components, using the first letter of each component's pinyin spelling.

He joined the Communist Party in May 1991.

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