Louis-Victor-Pierre-Raymond, 7th duc de Broglie (August 15, 1892 - March 19, 1987) was a French physicist. His 1924 Research on the Theory of the Quanta, introduced his theory of electron waves. This included the wave-particle duality theory of matter, based on the work of Max Planck and Albert Einstein on light. The thesis examiners, unsure of the material, passed his thesis to Einstein for evaluation who endorsed his wave-particle duality proposal. This research culminated in the de Broglie hypothesis stating that any moving particle or object had an associated wave. He thus created a new field in physics, wave mechanics, uniting the physics of energy (wave) and matter (particle). For this he won the Nobel Prize in Physics in 1929. In addition to strictly scientific work, de Broglie thought and wrote about the philosophy of science, including the value of modern scientific discoveries. He became a member of the Acad矇mie des sciences in 1933, and was the academy's perpetual secretary from 1942. He was awarded a post as counselor to the French High Commission of Atomic Energy in 1945 for his efforts to bring industry and science closer together. UNESCO awarded him the first Kalinga Prize in 1952 for his work in popularizing scientific knowledge, and he was elected a Foreign Member of the Royal Society in 1953. In 1961 he received the title of Knight of the Grand Cross in the L矇gion d'honneur. He died in 1987 at the age of 94.
