Birth – August 15, 1892 (Dieppe, France)
Death – March 19, 1987 (Paris, France)
Awarded Nobel Prize in Physics (1929) –
Discovery of the Wave Nature of Electrons (Wave-Particle Duality)
~Introduced theory of electron waves –
Doctoral thesis: “Researches on the quantum theory”
“Having much more the state of mind of a pure theoretician than that of
an experimenter or engineer, loving especially the general and
philosophical view, I was drawn towards the problems of atomic
physics…It was the conceptual difficulties which these problems raised;
it was the mystery which surrounded that famous Planck’s constant, h,
which measures the quantum of action; it was the disturbing and badly-
defined character of the dualism of waves and corpuscles, which
appeared to assert itself more and more in the realms of physics…”
~Born in Dieppe, France
~”De Broglie” family name –
Derived from small town in Normandy, France
~Louis-Victor de Broglie –
2nd Son of French Nobility, Brother - Maurice
~Father: Victor, 5th duc de Broglie

Sciences

~Became 7th duc de Broglie after Maurice’s death
~Influenced by Planck’s studies and Einstein’s proposals regarding
wavelengths composition of particles and the particle nature of light –
De Broglie proposed Wave-Particle Duality –
Particles behave as waves and waves behave as particles
~Distance between two successive crests of De Broglie wave –
De Broglie wavelength
