Jun-ichi Igusa (井草 凖一, Igusa Jun’ichi, 30 January 1924 – 24 November 2013) was a Japanese mathematician who for over three decades was on the faculty at Johns Hopkins University. He is known for his contributions to algebraic geometry and number theory. The Igusa zeta-function, the Igusa quartic, Igusa subgroups, Igusa curves, and Igusa varieties are named after him.[1]

He was an invited speaker for the 1962 International Congress of Mathematicians in Stockholm.[2] He was awarded Japan's Order of the Sacred Treasure.[3] In 2012 he became a fellow of the American Mathematical Society.[4]

Life and career

Igusa was born in Kiyosato village, Gunma Prefecture, Japan, on 30 January 1924.[5] He graduated from the University of Tokyo in 1945 and received his Ph.D. from Kyoto University in 1953, after which he became professor of mathematics at the University of Tsukuba. After a brief period spent at Harvard University, he took up a permanent position at Johns Hopkins University, in Baltimore. Igusa taught at Johns Hopkins from 1955 to 1993.[6] He joined the staff of the American Journal of Mathematics as an associate editor in 1964, and served as chief editor between 1978 and 1993.[7] Igusa died, aged 89, of a stroke at Holly Hill Nursing Home in Towson, Maryland, on 24 November 2013.[6]

He had three sons, Kiyoshi, Takeru and Mitsuru.[1] Takeru Igusa is a professor of civil engineering at Johns Hopkins University. Kiyoshi Igusa is a professor of mathematics at Brandeis University.
