Yoichiro Nambu, Japanese-American physicist and academic, Nobel Prize laureate (b. 1921)
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. Known for his contributions to the field of theoretical physics, he was awarded half of the Nobel Prize in Physics in 2008 for the discovery in 1960 of the mechanism of spontaneous broken symmetry in subatomic physics, related at first to the strong interaction's chiral symmetry and later to the electroweak interaction and Higgs mechanism. 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."
