{"aliases":[],"awards":["Nobel Prize in Chemistry","Humboldt Research Fellowship","Wilbur Cross Medal","Humboldt Prize"],"biography_summary":"John Bennett Fenn (June 15, 1917December 10, 2010) was an American analytical chemist who was awarded a share of the Nobel Prize in Chemistry in 2002, sharing half of the award with Koichi Tanaka for their work in mass spectrometry (the other half went to Kurt W\u00fcthrich). His contributions related to the development of electrospray ionization, now a commonly used technique for large molecules and routine liquid chromatography-tandem mass spectrometry. Early in his career, he studied the field of jet propulsion at Project SQUID and focused on molecular beams. He finished his career with more than 100 publications, including one book. Fenn was born in New York City, and moved to Kentucky with his family during the Great Depression. Fenn did his undergraduate work at Berea College, and received his PhD from Yale. He worked in industry at Monsanto and at private research labs before moving to academic posts including Yale and Virginia Commonwealth University. Fenn's research into electrospray ionization found him at the center of a legal dispute with Yale University. He lost the lawsuit, after it was determined that he misled the university about the potential usefulness of the technology. Yale was awarded $500,000 in legal fees and $545,000 in damages. The decision pleased the university, but provoked mixed responses from some people affiliated with the institution, who were disappointed with the treatment of a Nobel Prize winner with such a long history at the school.","birth_date":"1917-06-15","birth_place":"New York City","birth_place_coordinates":{"latitude":40.712778,"longitude":-74.006111},"birth_place_wikidata_id":"Q60","birth_place_wikidata_url":"https://www.wikidata.org/wiki/Q60","canonical_name":"John Fenn","canonical_url":"https://fr.instaget.online/people/7b801291b3236b4412ab6c95","citizenships":["United States"],"death_date":"2010-12-10","description":"chimiste am\u00e9ricain","external_ids":{"isni":{"id":"0000000107880803","url":"https://isni.org/isni/0000000107880803"},"loc":{"id":"n81113683","url":"https://id.loc.gov/authorities/names/n81113683.html"},"viaf":{"id":"112003589","url":"https://viaf.org/viaf/112003589/"}},"full_name":"John B.
