Biography

Mitio Nagumo graduated from the Department of Mathematics at the

Imperial University of Tokyo. In the 1960s he made a number of academic visits abroad, spending time at the Courant Institute of Mathematical Sciences (where he visited Kurt Friedrichs and other old acquaintances from his time at Göttingen) and the Federal University of Rio Grande do Sul in 1960, followed by a visit to the National Tsing Hua University in 1963-64. He retired from Osaka University in December 1966, after which he was granted the title of Honorary Professor. He was subsequently appointed Professor at Sophia University, from which he retired in March 1976, having reached mandatory retirement age.[1]

Much of Nagumo's original work was published in Japanese and German,[1] however his research and teaching have influenced numerous mathematicians (especially in Japan) who have since made many of his results available in English.[4]
