Yoichiro Nambu (南部 陽一郎, Nanbu Yōichirō, 18 January 1921 – 5 July 2015) was a Japanese-American physicist and professor at the University of Chicago.[1]

Known for his contributions to the field of

chiral symmetry and later to the electroweak interaction and Higgs mechanism.[2]

The other half was split equally between

Makoto Kobayashi and Toshihide Maskawa "for the discovery of the origin of the broken symmetry which predicts the existence of at least three families of quarks in nature."[2]

Early life and education

Nambu was born in

Fukui City, he enrolled in the Imperial University of Tokyo and studied physics. He received his Bachelor of Science in 1942 and Doctorate of Science in 1952.[2] In 1949 he was appointed to associate professor at Osaka City University[3] and promoted to professorship the next year at the age of 29.[2]

In 1952, he was invited by the Institute for Advanced Study in Princeton, New Jersey, United States, to study. He moved to the University of Chicago in 1954 and was promoted to professor in 1958.[4] From 1974 to 1977 he was also Chairman of the Department of Physics.[5] He became a United States citizen in 1970.[6]

Career in physics

Nambu proposed the "color charge" of quantum chromodynamics,[7] having done early work on spontaneous symmetry breaking in particle physics,[8] and having discovered that the dual resonance model could be explained as a quantum mechanical theory of strings.[9][10] He was accounted as one of the founders of string theory.[11]

After more than fifty years as a professor, he was Henry Pratt Judson Distinguished Service

Professor emeritus at the University of Chicago's Department of Physics and Enrico Fermi Institute.[12][13]

The

Death

Nambu died on 5 July 2015 at the age of 94 in Osaka due to a heart attack.[16][17] His funeral and memorial services were held among close relatives.[16]

Recognition

Nambu won numerous honors and awards including the Dannie Heineman Prize (1970), the J. Robert Oppenheimer Memorial Prize (1977),[18][19] Japan's

Benjamin Franklin Medal (2005).[3][20]
He was awarded one-half of the 2008 Nobel Prize in Physics "for the discovery of the mechanism of spontaneous broken symmetry in subatomic physics".[2][21][22]
