Louis de Broglie
Nobel laureate credited to pioneer the discovery of wave character of matter (1892–1987)
Louis Victor Pierre Raymond, 7th Duc de Broglie was a French theoretical physicist and aristocrat known for his contributions to quantum theory. In his 1924 Ph.D. thesis, de Broglie 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. In 1929, de Broglie won the Nobel Prize in Physics, after the wave-like behaviour of matter was experimentally confirmed in 1927. This confirmation earned George Paget Thomson and Clinton Davisson the Nobel in 1937.
