After studying under William Ramsay at University College London,[1] he joined the New Hampshire College of Agriculture and the Mechanic Arts (now the University of New Hampshire). He became a professor and head of the chemistry department,[2] separating and identifying rare-earth elements by fractional precipitation and crystallization. He isolated element 71, later named lutetium. In 1999 the American Chemical Society recognized Charles James's work in chemical separations as a National Historic Chemical Landmark.[1] References1. ^1 {{cite web | title = Separation of Rare Earth Elements by Charles James | work = National Historic Chemical Landmarks | publisher = American Chemical Society | url = http://www.acs.org/content/acs/en/education/whatischemistry/landmarks/earthelements.html | accessdate = 2014-02-21 }} {{Authority control}}{{DEFAULTSORT:James, Charles}}{{Chemist-stub}} 2. ^{{cite web | url=http://unhmagazine.unh.edu/f10/charles_james_pf.html | title=UNH Magazine: UNH Magazine - The Life and Work of Charles James | accessdate=2012-01-09}} 4 : 1880 births|1928 deaths|Alumni of University College London|Discoverers of chemical elements |
