He was also a pioneer of quantum chromodynamics (QCD), one of the founding figures of string theory, and the proposer of Nambu mechanics. In addition, he co-created the  Nambu–Jona-Lasinio model, which explained the dynamical origin of mass in nucleons.","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\"."],"facts":[{"key":"born","label":"Born","values":[{"text":"18 January 1921","date":"1921-01-18"}],"source":{"label":"Wikidata","url":"https://www.wikidata.org/wiki/Q188120#P569"}},{"key":"birthplace","label":"Place of birth","values":[{"text":"Tokyo","wikidata":"https://www.wikidata.org/wiki/Q7473516"}],"source":{"label":"Wikidata","url":"https://www.wikidata.org/wiki/Q188120#P19"}},{"key":"died","label":"Died","values":[{"text":"5 July 2015","date":"2015-07-05"}],"source":{"label":"Wikidata","url":"https://www.wikidata.org/wiki/Q188120#P570"}},{"key":"deathplace","label":"Place of death","values":[{"text":"Toyonaka","wikidata":"https://www.wikidata.org/wiki/Q467479"}],"source":{"label":"Wikidata","url":"https://www.wikidata.org/wiki/Q188120#P20"}},{"key":"citizenship","label":"Citizenship","values":[{"text":"United States","wikidata":"https://www.wikidata.org/wiki/Q30","start":"1970"},{"text":"Japan","wikidata":"https://www.wikidata.org/wiki/Q17"}],"source":{"label":"Wikidata","url":"https://www.wikidata.org/wiki/Q188120#P27"}},{"key":"occupation","label":"Occupation","values":[{"text":"theoretical physicist","wikidata":"https://www.wikidata.org/wiki/Q19350898"},{"text":"professor","wikidata":"https://www.wikidata.org/wiki/Q121594"},{"text":"physicist","wikidata":"https://www.wikidata.org/wiki/Q169470"},{"text":"researcher","wikidata":"https://www.wikidata.org/wiki/Q1650915"}],"source":{"label":"Wikidata","url":"https://www.wikidata.org/wiki/Q188120#P106"}},{"key":"education","label":"Education","values":[{"text":"University of Tokyo","wikidata":"https://www.wikidata.org/wiki/Q7842","end":"1952"},{"text":"Princeton University","wikidata":"https://www.wikidata.org/wiki/Q21578"},{"text":"Fukui Prefectural Fujishima High School","wikidata":"https://www.wikidata.org/wiki/Q5507643"}],"source":{"label":"Wikidata","url":"https://www.wikidata.org/wiki/Q188120#P69"}},{"key":"awards","label":"Awards","values":[{"text":"Guggenheim Fellowship","wikidata":"https://www.wikidata.org/wiki/Q1316544"},{"text":"Order of Culture","wikidata":"https://www.wikidata.org/wiki/Q530124","date":"1978"},{"text":"Nobel Prize in Physics","wikidata":"https://www.wikidata.org/wiki/Q38104","date":"2008"},{"text":"Benjamin Franklin Medal","wikidata":"https://www.wikidata.org/wiki/Q817496","date":"2005"},{"text":"Oskar Klein Medal","wikidata":"https://www.wikidata.org/wiki/Q1778662","date":"2005"},{"text":"National Medal of Science","wikidata":"https://www.wikidata.org/wiki/Q737051","date":"1982"},{"text":"Max Planck Medal","wikidata":"https://www.wikidata.org/wiki/Q317038","date":"1985"},{"text":"Wolf Prize in Physics","wikidata":"https://www.wikidata.org/wiki/Q845333","date":"1994"},{"text":"Person of Cultural Merit","wikidata":"https://www.wikidata.org/wiki/Q2545449","date":"1978"},{"text":"J.
