Louis de Broglie

Louis de Broglie (1892–1987) was a French theoretical physicist and aristocrat renowned for proposing the wave nature of electrons in his 1924 Ph.D. thesis, introducing wave-particle duality to quantum theory and founding wave mechanics. He received the Nobel Prize in Physics in 1929 for this discovery and later pursued causal interpretations of quantum mechanics, influencing the De Broglie–Bohm theory.
