About Hiroshi Inose
Lived 1927 – 2000 (aged 73). Hiroshi Inose was a Japanese engineer and computer scientist.
was a Japanese electrical engineer, known as the inventor of the Time-Slot Interchange system (TSI), which is basic to modern digital telephone switches. Inose was highly involved within his career. He held positions such as director general, chairman, associate professor, and president specific committees pertaining to engineering and technology. He was awarded with many honorific titles. In 1976 he received the Marconi Prize, in 1993 the Harold Pender Award, and in 1994 the IEEE Alexander Graham Bell Medal.
Life Hiroshi Inose was born in Nezu, Tokyo in Japan on January 5, 1927. He obtained his Bachelor of Engineering degree from the University of Tokyo in 1948 and his doctorate degree there in 1955, respectively. Inose married his wife Mariko in 1960.
From 1956 to 1958, Inose was an associate at the University of Pennsylvania and employed as a consultant at the Bell Telephone Laboratories in Murray Hill, New Jersey where he invented the TSI system. This system was the basis of the digital telephone switches.
Aside from his invention, he became an associate professor in the Faculty of Engineering at the University of Tokyo in 1958 and in 1961 was promoted to full professor. Inose also served as the Dean of the Faculty of Engineering as well as Director for the Computer Center and the Center for Bibliographic Information. He "...spent sabbatical terms at the University of Pennsylvania, Philadelphia, and the University of Michigan, Ann Arbor." Although this invention was crucial, it did not receive much recognition due to costly memory devices. Later in the 1970s when semiconductor technologies began advancing, TSI received more recognition. Since its first commercial deployment in 1976, it has been popular and utilized amongst the digital central office switching systems and digital private branch exchanges.
The National Institute for Informatics
The NII was designed to integrate research and development in information and communication science and for development of academic research and education informatics infrastructure. Upon establishing the institute, Inose encouraged researchers to focus on "..."real world problems" in formulating their research programs and to address..." the problems alongside scientific issues they often focus on. One of Inose's main goals for the NII was to create an interdisciplinary approach to research in which they take part in inter-sectoral collaboration with academia, government, and industrial laboratories.
Publications During Inose's time, he made many publications. Over 150 articles that he published were in Japanese and international professional journals. Aside from publishing articles in Japanese, Inose also published several books in English. Some of his publications consist of An Introduction to Digital Integrated Communications Systems, Information Technology and Civilization (published with John R. Pierce, Road Traffic Control (published with Takashi Hamada) and Creativity and Culture (published with Stephen Jay Gould). 1977 - elected to the United States National Academy of Sciences 1979 - elected to the American Philosophical Society 1979 - Japan Academy Prize 1993 - Harold Pender Award 1994 - IEEE Alexander Graham Bell Medal
