Jun-Ichi Igusa (井草 準一, Igusa Jun’ichi, 30 January 1924 − 25 November 2013)[1] 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.[2]

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

He has three sons, Kiyoshi, Takeru and Mitsuru.[5] Takeru Igusa is a professor of civil engineering at Johns Hopkins University. Kiyoshi Igusa is a professor of mathematics at Brandeis University.
