Died: 13 July 1921, Atlantic Ocean
Affiliation at the time of the award: Sorbonne University, Paris, France
Prize motivation: "for his method of reproducing colours photographically based on the phenomenon of interference."
Prize share: 1/1
During the 19th century methods were developed for producing black-and-white photographs with the help of light-sensitive silver halides. In the 1890s Gabriel Lippmann discovered a method for color photography based on interference - interaction between light waves. Using a mirror, light was reflected through a photographic emulsion in which the interference phenomenon produces a number of blackened layers. The distance between the layers corresponds to certain wavelengths and can be transmuted into a color image. The method never came into widespread usage, but lived on as a physics experiment.
Their work and discoveries range from cancer therapy and laser physics to developing proteins that can solve humankind’s chemical problems. The work of the 2018 Nobel Laureates also included combating war crimes, as well as integrating innovation and climate with economic growth. Find out more.
