Louis de Broglie Biography

Louis Victor Pierre Raymond de Broglie, duke de Broglie (/dəˈbrɔɪ/; French: [dəbʁɔj] or [dəbʁœj] ( listen); 15 August 1892 – 19 March 1987) was a French physicist who made groundbreaking contributions to quantum theory. In his 1924 PhD thesis he postulated the wave nature of electrons and suggested that all matter has wave properties. This concept is known as the de Broglie hypothesis, an example of wave–particle duality, and forms a central part of the theory of quantum mechanics.
