Louis victor de-broglie
- 1. Birth – August 15, 1892 (Dieppe, France) Death – March 19, 1987 (Paris, France)
- 2. Awarded Nobel Prize in Physics (1929) – Discovery of the Wave Nature of Electrons (Wave-Particle Duality) ~Introduced theory of electron waves – Doctoral thesis: “Researches on the quantum theory” “Having much more the state of mind of a pure theoretician than that of an experimenter or engineer, loving especially the general and philosophical view, I was drawn towards the problems of atomic physics…It was the conceptual difficulties which these problems raised; it was the mystery which surrounded that famous Planck’s constant, h, which measures the quantum of action; it was the disturbing and badly- defined character of the dualism of waves and corpuscles, which appeared to assert itself more and more in the realms of physics…”
