Often associated with Reed McNeil Izatt, Pedersen also shared the Nobel Prize in Chemistry in 1987 with Donald J. Cram and Jean-Marie Lehn. He is one of three Nobel Prize laureates born in Korea, along with Peace Prize laureate Kim Dae-jung and Literature laureate Han Kang.","summary_more":["Pedersen made many other discoveries in chemistry, such as discovering and developing metal deactivators. His early investigations also led to the development of a dramatically improved process for manufacturing tetraethyl lead, an important gasoline additive. He also contributed to the development of neoprene."],"facts":[{"key":"born","label":"Born","values":[{"text":"3 October 1904","date":"1904-10-03"}],"source":{"label":"Wikidata","url":"https://www.wikidata.org/wiki/Q244998#P569"}},{"key":"birthplace","label":"Place of birth","values":[{"text":"Busan","wikidata":"https://www.wikidata.org/wiki/Q16520"}],"source":{"label":"Wikidata","url":"https://www.wikidata.org/wiki/Q244998#P19"}},{"key":"died","label":"Died","values":[{"text":"26 October 1989","date":"1989-10-26"}],"source":{"label":"Wikidata","url":"https://www.wikidata.org/wiki/Q244998#P570"}},{"key":"deathplace","label":"Place of death","values":[{"text":"Salem","wikidata":"https://www.wikidata.org/wiki/Q1088317"}],"source":{"label":"Wikidata","url":"https://www.wikidata.org/wiki/Q244998#P20"}},{"key":"citizenship","label":"Citizenship","values":[{"text":"United States","wikidata":"https://www.wikidata.org/wiki/Q30"},{"text":"Japan","wikidata":"https://www.wikidata.org/wiki/Q17"}],"source":{"label":"Wikidata","url":"https://www.wikidata.org/wiki/Q244998#P27"}},{"key":"occupation","label":"Occupation","values":[{"text":"chemist","wikidata":"https://www.wikidata.org/wiki/Q593644"},{"text":"researcher","wikidata":"https://www.wikidata.org/wiki/Q1650915"}],"source":{"label":"Wikidata","url":"https://www.wikidata.org/wiki/Q244998#P106"}},{"key":"education","label":"Education","values":[{"text":"Massachusetts Institute of Technology","wikidata":"https://www.wikidata.org/wiki/Q49108"},{"text":"Saint Joseph College, Yokohama","wikidata":"https://www.wikidata.org/wiki/Q7401550"},{"text":"University of Dayton","wikidata":"https://www.wikidata.org/wiki/Q2092392"}],"source":{"label":"Wikidata","url":"https://www.wikidata.org/wiki/Q244998#P69"}},{"key":"awards","label":"Awards","values":[{"text":"Nobel Prize in Chemistry","wikidata":"https://www.wikidata.org/wiki/Q44585","date":"1987"},{"text":"Lavoisier Medal for Lifetime Technical Achievement","wikidata":"https://www.wikidata.org/wiki/Q114847999","date":"1991"}],"source":{"label":"Wikidata","url":"https://www.wikidata.org/wiki/Q244998#P166"}}],"office":null,"sections":[],"cited":[],"cited_from":null,"videos":[],"last_reviewed":null,"organizations":[],"same_as":["https://en.wikipedia.org/wiki/Charles_J._Pedersen","https://www.wikidata.org/wiki/Q244998"],"faq":[{"q":"When was Charles J.
