Why Is John Reynolds Influential?

(Suggest an Edit or Addition)

According to Wikipedia, John Hamilton Reynolds was an American physicist and a specialist in mass spectrometry. Life John H. Reynolds was born in Cambridge, Massachusetts, United States. He studied first at Harvard University and, after serving in the Navy during World War II, at the University of Chicago. There, he was influenced by his Ph.D. thesis advisor Mark Inghram and by two other famous physicists, Harold Urey and Enrico Fermi. He specialized in mass spectrometry and utilized this method to determine isotope ratios needed for the radiometric dating of geologically and cosmologically relevant samples. In 1950 he was appointed as professor to the University of California, Berkeley where he continued his research on isotope ratios in meteorites, leading to the discovery in 1960 that the Richardton meteorite and other meteorites had an excess of xenon-129, thought to be a result of the beta decay of iodine-129 in the early Solar System. His improvement of potassium-argon dating was adopted by several institutions.
