Japanese Computer Pioneers

Amemiya AyaoAmemiya Ayao
1907〜1977

Amemiya Ayao was born in 1907. He graduated from the Department of Physics of the Faculty of Science, the University of Tokyo in 1931. He started the study of atom and molecule and completed the famous "Kotani-Amemiya Table" in that field.
From the experience of the pains of the numerical computation of that work, he decided to be deeply involved in the development of the TAC of the University of Tokyo. The project TAC of the University of Tokyo means large digital computer project in the early stages of Japan.

Afterwards, he shifted to the research of Polymer Physics. He achieved remarkable works in the field. He held consecutively a professor of the University of Tokyo and the University of Electro-Communications. After he retired from the latter university in 1973, he died in 1977.

The project TAC of the University of Tokyo means large digital computer project in the early stages of Japan. He was actually the chief of the project TAC from the start of the project until the end (1951-1959). He supervised the seminar on the programming of computer for the first time (around 1953). It was the textbooks of Maurice Wilkes that he chose for the seminar. Through the seminar, he brought up many researchers. Amemiya also brought up the hardware researchers Murata Kenro, Nakazawa Kisaburo, and so on.
In his later years, he again studied numerical computations and supervised his pupils, such as Mori Masatake and Natori Makoto. He contributed to the completion of the library of linear algebra and special functions. The library was for the computer center of the University of Tokyo for the first time. That result was published in the technical book "Numerical Computation and FORTRAN" It was an only useful book with source code those days. (1969, Maruzen)
