Takashi Ono (mathematician)

Takashi Ono (小野 孝, Ono Takashi, born 18 December 1928) is a retired Japanese-born American mathematician, specializing in number theory and algebraic groups.

Ono was born in Nishinomiya, Japan. He received his Ph.D. in 1958 at Nagoya University.^[1]

Ono immigrated to the United States after receiving an invitation from J. Robert Oppenheimer to work at the Institute for Advanced Study with a fellowship for the two academic years from 1959 to 1961^[2] and then went to the University of British Columbia to work as an assistant professor of mathematics^[3] from 1961 to 1964. From 1964 to 1969 Ono was a tenured professor at the University of Pennsylvania. From 1969 to his retirement in 2011, he was a professor at Johns Hopkins University. In 1966 he was an invited speaker at the International Congress of Mathematicians in Moscow.^[2] In 2012 he was elected a Fellow of the American Mathematical Society.^[4]

Ono's youngest son, Ken Ono, is also a mathematician^[5] and professor at the University of Virginia as well as a former triathlete.^[6] His middle son, Santa J. Ono, is serving as the 15th President of the University of Michigan (previously the President and Vice-Chancellor of the University of British Columbia) and is a biomedical researcher. His eldest son, Momoro Ono, is a music professor at Creighton University.^[7]
