Executive summary: Discovered the wave nature of electrons Military service: French Army (WWI) French quantum physicist Louis de Broglie introduced his theory of particle-wave duality in 1924. In his time, the wave and particle interpretations of light and matter were seen as being at odds with one another, but de Broglie suggested that these seemingly different characteristics were instead the same behavior observed from different perspectives — that particles can behave like waves, and waves (radiation) can behave like particles. It was originally written as his doctoral thesis, but his advisors at the Sorbonne concluded that they could not fully assess its merit, and suggested that he send Albert Einstein a copy for evaluation. Einstein wrote back almost immediately, and stated that de Broglie had unraveled one of the secrets of the universe. His theory helped explain how atoms, molecules, and protons behave, inspired Erwin Schrِdinger in the formulation of wave mechanics, and earned de Broglie the Nobel Prize for Physics in 1929. He also studied atomic energy, cybernetics, gamma rays, optics, particle accelerators, x-rays, and wave-guides. In 1949 de Broglie became the first high-level scientist to call for establishment of a multi-national laboratory, a proposal that led to the establishment of the European Organization for Nuclear Research (CERN). His brother was physicist Maurice de Broglie, and by heredity they were both French dukes and German princes.
