Louis-Victor-Pierre-Raymond, 7th duc de Broglie, ForMemRS was an eminent French physicist who gained worldwide acclaim for his groundbreaking work on quantum theory. In his 1924 thesis, he proposed the wave nature of electrons and suggested that all matter has wave properties - this concept is known as wave-particle duality or the de Broglie hypothesis. He won the Nobel Prize for Physics in 1929. The wave-like behaviour of particles discovered by de Broglie was used by Erwin Schrödinger in his formulation of wave mechanics. Louis de Broglie was the sixteenth member elected to occupy seat 1 of the Académie française in 1944, and served as Perpetual Secretary of the French Academy of Sciences.
