Tatsujiro Shimizu

Life and career

Shimizu graduated from the Department of Mathematics, School of Science, Tokyo Imperial University in 1924, and stayed there working as a staff member. In 1932 he moved to Osaka Imperial University and became a professor. He made contributions to the establishment of the Department of Mathematics there. In 1949, Shimizu left Osaka and took up a professorship at Kobe University. After two years, he moved again to Osaka Prefectural University. From 1961 he was a professor at the Tokyo University of Science.

In 1948, seeing the difficulty in publication of paper in mathematics, Shimizu started a new journal Mathematica Japonicae, for papers of pure and applied mathematics in general, on his own funds. The journal served as the foundation of the Japanese Association of Mathematical Sciences.

Shimizu remained active in mathematics into old age. He gave talks at the meeting of the Mathematical Society of Japan until 90 years old. He died in Uji City, Kyoto Prefecture, on November 8, 1992, at the age 95.
