Roy Jay Glauber (born 1 September 1925) is the Mallinckrodt Professor of Physics at Harvard University and Adjunct Professor of Optical Sciences at the University of Arizona. Born in New York City, he was awarded one half of the 2005 Nobel Prize in Physics "for his contribution to the quantum theory of optical coherence", with the other half shared by John L. Hall and Theodor W. Hänsch. His groundbreaking research on optical coherence was published in 1963. The most famous contribution of Roy Glauber to physics, for which he was awarded the Nobel Prize, is the notion and mathematics behind coherent states.

A student in the 1941 graduating class at the Bronx High School of Science, Glauber worked on the Manhattan Project for two years before obtaining his bachelor's degree and then went on to obtain a PhD from Harvard University. The Bronx High School of Science, commonly called Bronx Science, is a public high school in the Bedford Park section of the Bronx, New York City. ...

He is also the 'Keeper of the Broom' at the Ig Nobel Prize ceremonies, sweeping the stage clean of the paper aeroplanes that are traditionally thrown during the event. The Ig Nobel Prizes are a parody of the Nobel Prizes and are given each year in early fall — around the time the recipients of the genuine Nobel Prizes are announced — for ten achievements that first make people laugh, and then make them think. ...
