Louis Victor Pierre Raymond Duc De Broglie was born in Dieppe (France) on 15 August 1892. He studied history at the Sorbonne in Paris, wanting to pursue a career in the diplomatic service. At the age of eighteen years he began to study physics, and then only after studying literature, obtaining a degree in history and law in 1910 (just 18). De Broglie was well known for his theory on the wave particle duality, which had the property of the particles be waves. His thesis for the doctorate of 1924 proposed this theory of electron waves based on the work of Einstein and Planck. The wave nature of the electron was confirmed experimentally in 1927 by C.J. Davsson, C.H. Kunsman and L.H. Germer in the United States, and G.P. Thomsom in Scotland.
Louis De Broglie in a 1963 interview he described how he arrived at his findings as follows: "As in my conversations with my brother, we came to the conclusion, that in the case of x-rays, one had had both waves and particles, so suddenly ... so it was certainly happened in 1923. I had the idea that one had extended this duality for material particles, especially for electrons. And I realized that on the one hand, the Hamilton-Jacobi theory jabbed something in this direction, which is why it was possible to apply it to particles, and in addition was a geometric eye; on the other side in quantum phenomena one obtained quantum numbers, which had rarely can find them in mechanics, but that wave phenomena, and needed frequently in all problems dealing with a movement of the wave."
After his Ph.d. De Broglie remained at the Sorbonne in Paris, becoming a Professor of theoretical physics at the Institute Henri Poincaré in 1928. He taught until 1962. In 1945, he became an adviser to the French Atomic Energy Commissariat. De Broglie's theory on the problem of electron waves was later used by Schrödinger to see mechanical waves. De Broglie was awarded the Nobel Prize in 1929. He wrote many popular works that demonstrate your interest in the philosophical implications of modern physics, including "light and matter"; "The New Physics" (new physics in 1939); "The Revolution in Physics" (the revolution in Physics in 1953); "Phisycs and Microphysics" (physics and Microphysics in 1960); "The New Perspectives in Physics" (new perspectives in Physics in 1962).
The central issue in the life of De Broglie was if the statistical nature of the atom was at the base of an ignorance that reflect physical theory, or if this statistic was all that could be known. For a long time he believed at first, though he was a young researcher, in fact at first believed that the statistics hide our ignorance. Perhaps surprised, returned to this view late in his life, stating that "a strong and perfect statistics theories a reality found behind variables that circumvent our experimental techniques." Louis de Broglie died on March 19, 1987 in Louveciennes, at the ripe old age of 94 years.
