His father was the 6th Duc de Broglie and Louis in the course of time became the 8th Duc de Broglie.

He was a prince and as such was expected to pursue a gentlemanly career and uphold the family traditions.

Louis did earn a degree in literary studies in 1910.

But his older brother, Maurice, became a physicists and had the great good fortune of being able to attend the Solvay Conference where Albert Einstein and the other top physicists of the day debated the nature of reality in the formulation of Quantum Physics.

Once he had examined the possible formulations for consistency he did not take much to space to present the final results.

The equation he presented for the wave-length λ associated with a particle is where h is Planck's constant and p is the momentum of the particle.This would prove crucial to the development of quantum mechanics.It is now an integral part of the theory of atomic structure and particle physics.In 1924 he presented the results of his thinking in the form of a thesis entitled "Recherches sur la Théorie des Quanta," (Research on Quantum Theory).His thesis was notable not only for the strangeness of the ideas but its shortness.Louis de Broglie subsequently, in 1932, was made professor of theoretical physics at the University of Paris. But to explain the way in which my research came to develop I must first outline the critical period through which Physics had for the last twenty years been passing.Physicists had for long been wondering whether Light did not consist of minute corpuscles in rapid motion, an idea going back to the philosophers of antiquity, and sustained in the eighteenth century by Newton.The resulting diffraction pattern matched the predictions of the de Broglie wavelength.De Broglie received the 1929 Nobel Prize for his theory (the first time it was ever awarded for a Ph. thesis) and Davisson/Germer jointly won it in 1937 for the experimental discovery of electron diffraction (and thus the proving of de Broglie's hypothesis).He soon began teaching physics first at the Sorbonne and later at the Henri Poincaré Institute. Below is given the text of the speech Louis de Broglie delivered in Stockholm upon receiving the Nobel Prize in Physics in 1929, When, in 1920, I resumed my investigations in theoretical Physics after a long interruption through circumstances out of my own control, I was far from imagining that this research would within a few years be rewarded by the lofty and coveted distinction given each year by the Swedish Academy of Sciences: the Nobel Prize in Physics.He received the Nobel Prize in Physics in 1929 after experiments by Clinton Davisson and Lester Germer published in 1927 proved his analysis to be correct. At that time what drew me towards theoretical Physics was not the hope that so high a distinction would ever crown my labours: what attracted me was the mystery which was coming to envelop more and more deeply the structure of Matter and of radiation in proportion as the strange concept of the quantum, introduced by Planck about 1900 during his research on black body radiation, came to extend over the entire field of Physics.
