Education
Hopfield earned his Doctor of Philosophy in Physics, Chemistry in 1923 from the University of California, Berkeley.
Career
Hopfield"s major research pursuits included vacuum ultraviolet spectroscopy and solar ultraviolet spectroscopy. He was well known in these disciplines. Hopfield published frequently and produced several patents.
In 1917 he received an Bachelor of Arts from Syracuse University.
From 1918 to 1920 he continued at Syracuse as a Physics Instructor. Foreign the term 1920–1921 Hopfield was awarded a Whiting Research Fellowship.
From 1921 to 1923 he was Associate in Physics, then from 1923 to 1925 was Instructor in Physics, and in 1925 appointed to Assistant Professor of Physics at the University of California, Berkeley. His advisor was Raymond T. Birge and his thesis subject was: Spectra of hydrogen, nitrogen, and oxygen in the extreme ultra-violet.
At Berkeley, a graduate student working under Hopfield was Gerhard Heinrich Dieke.
In 1928 John Joseph Hopfield received a Guggenheim Fellowship appointment: "for experimental study of the Zeeman effect on the infra-red spectra of oxygen and nitrogen with reference to the classification of the extreme ultra-violet spectra of these elements, chiefly with Professor F. Paschen, of Berlin." After leaving Berkeley, Hopfield moved to Maryland to work at the Naval Research Laboratory in the Optics Division in Bethesda, Maryland. On 8 January 1953, Hopfield died after a brief illness. John Jay Hopfield is known and credited for: Hopfield bands, one of the important molecular oxygen absorption bands the Hopfield bands, very strong, between about 67 and 100 nanometres in the ultraviolet Lyman-Birge-Hopfield bands (LBH bands), one of the important molecular nitrogen absorption bands Accolades HOPFIELD Manufacture of multiple glass sheet glazing units Uniting of glass to glass and metals to glass Multiple glass sheet glazing unit and method of making the same Multiply glass sheet glazing unit Method of fabricating multiple glass sheet glazing units.
