Murata Kenro was born on Oct. 4, 1923. He graduated from the Department of Aircraft Engine, the Faculty of Engineering of the University of Tokyo in 1945 and the Department of Mathematics, the Faculty of Science of the University of Tokyo in 1951. Around the middle of 1952, he studied under Amemiya Ayao of the Department of Applied Physics of the University of Tokyo. He joined the computer project TAC of the University. After several meanderings, he and Nakazawa Kisaburo began the complete reformation of TAC at the end of 1957 and completed in Jan. 1959. After that the computer was enhanced the performance by them and it was used mainly by the researchers of the Faculty of Engineering of the University until the summer of 1962.

He joined Hitachi Ltd. with Nakazawa in Apr. 1960. He engaged in the development of HITAC 5020, which was delivered to the Large Scale Computer Center of the University of Tokyo as the first generation machine of that center in Oct. 1965.

He joined the project "Super-high-performance computer" of the Agency of Industrial Science and Technology of Japanese Government(1967-1972). The improved version of the machine was called HITAC 8800. It was delivered to the Large Scale Computer Center of the University of Tokyo as the second-generation computer in 1973.
Since around 1973, he shifted to the field of numerical computation. He developed a new method of the computation of the eigenvalue problem of the symmetric band matrix etc. motivated by the experience of some unconformity between some traditional arithmetic and the architecture of the virtual memory control.

He retired from Hitachi Ltd. in 1983. He held consecutively a professor of Univ. of Library and Information Science until 1989 and Kanagawa Univ. until 1993.

Doctor of Science (the University of Tokyo, 1962)
Purple Ribbon Medal (1973)

He died on July 27, 2009.
