Roy Glauber receives one half of the Nobel Prize in Physics "for his contribution to the quantum theory of optical coherence". The other half of the prize is splitted between two co-winners, John L. Hall and Theodor W. Hänsch.

Roy Glauber follows Wolfgang Pauli in Zürich until the fall of the same year, when Glauber comes back at Princeton.

Roy Glauber is born in New York City, first of three children to a traveling salesman and a teacher. As a child, Glauber enjoys reading Jules Verne, Alexandre Dumas and Sir Walter Scott. He shows artistic talent, fascination for electricity and passion for astronomy joining a Junior Astronomy Club. During his youth, he builds his own telescope, using it to take a picture of a lunar eclipse.

Roy Glauber attends the newly founded Bronx High School of Science. During these years, he builds a spectroscope that wins the city's science fair and is displayed at the 1939 World's Fair in New York as well as in its repetition in 1940.

Roy Glauber accepts a temporary teaching position at Caltech replacing Feynman. There, Glauber researches on electron diffraction by molecules and becomes interested in the scattering theory.

Roy Glauber returns to Harvard as professor. In 1963 he publishes his historic paper, “The Quantum Theory of Optical Coherence.” Since 1976 is Mallinckrodt Professor of Physics. Glauber's recent research deals with problems in a number of areas of quantum optics. He continues also working on several topics in high-energy collision theory.

Roy Glauber spends his first postdoctoral year in Princeton at the Institute for Advanced Study. There, he meets Wolfgang Pauli.

Roy Glauber earns his Ph.D. at Harvard University, after which he is proposed to spend a postdoctoral year in Princeton at the Institute for Advanced Study. In 1949, he presents his quantum field theoretical thesis written under Julian Schwinger.

Roy Glauber enters Harvard University with a Harvard Club scholarship.

At the age of 18, Roy Glauber is recruited to work on the Manhattan Project, to help calculating the critical mass for the atom bomb. He is one of the youngest scientists at Los Alamos. After two years there, he returns to Harvard to complete his Bachelor.

Glauber creates a model for photodetection. He defines the behaviour of light particles linking optics field with quantum physics, laying the basis for quantum optics. He explains how light has wavelike and particlelike characteristics, and clarifies the major differences between light emitted by hot objects and emitted by lasers. Hot objects emit incoherent light, which consists of different frequencies and phases, while lasers emit coherent light with a uniform frequency and phase.
