Born 1892 to a French noble family. De Broglie (pron 'de Broy') served as a radio communications technician during WWI, and it was in this capacity that he acquired the interest in physics that would win him the Nobel Prize in 1929. When de Broglie submitted his PhD thesis in 1924 he proposed the revolutionary idea that all matter displays wavelike behavior. This proposition caused much debate, but the examining committee approved de Broglie's doctorate despite the notable lack of evidence supporting his thesis. In 1927 experimental evidence verified de Broglie's proposal for electrons. Today his theory is generally accepted and is one of the basic propositions underlying modern quantum physics.
