Broglie, Prince Louis Victor de (1892–1987) French physicist who theorized that all elementary particles have an associated wave. He devised the formula that predicts this wavelength, and its existence was proven in 1927. Broglie developed this form of quantum mechanics, called wave mechanics, and was awarded the 1929 Nobel Prize in physics. Erwin Schrödinger advanced Broglie's ideas with his equation that describes the wave function of a particle.
