Biography

Born in Denver, Colorado, Hall holds three degrees from Carnegie Institute of Technology, a B.S. in 1956, an M.S. in 1958, and a Ph.D. in 1961. He completed his postdoctoral studies at the Department of Commerce's National Bureau of Standards, now the National Institute of Standards and Technology (NIST), where he remained from 1962 until his retirement in 2004. He has lectured at the University of Colorado Boulder since 1967.[1][2]

Hall is currently a NIST Senior Fellow, emeritus, and remains a Fellow at JILA, formerly the Joint Institute for Laboratory Astrophysics, and lecturer at the CU-Boulder Physics Department. JILA is a research institute managed jointly by CU-Boulder and NIST.

Hall shared half of the Nobel Prize with Theodor W. Hänsch for their pioneering work on laser-based precision spectroscopy and the optical frequency comb technique. The other half of the prize was awarded to Roy J. Glauber.

Hall has received many other honors for his pioneering work, including the Optical Society of America's Max Born Award "for pioneering the field of stable lasers, including their applications in fundamental physics and, most recently, in the stabilization of femtosecond lasers to provide dramatic advances in optical frequency metrology".

Hall is one of the 20 American recipients of the Nobel Prize in Physics to sign a letter addressed to President George W. Bush in May 2008, urging him to "reverse the damage done to basic science research in the Fiscal Year 2008 Omnibus Appropriations Bill" by requesting additional emergency funding for the Department of Energy’s Office of Science, the National Science Foundation, and the National Institute of Standards and Technology.[3]

In 2015, Hall signed the Mainau Declaration 2015 on Climate Change on the final day of the 65th Lindau Nobel Laureate Meeting. The declaration was signed by a total of 76 Nobel Laureates and handed to then-President of the French Republic, François Hollande, as part of the successful COP21 climate summit in Paris.[4]
