Louis de Broglie


The French physicist Louis de Broglie, b. Aug. 15, 1892, d. Mar. 19, 1987, is known for his theory that matter has the properties of both particles and waves. This particle-wave duality, derived from the work of Albert Einstein and Max Planck, was experimentally confirmed, for the electron, in 1927. De Broglie received the 1929 Nobel Prize for physics.

Born into a noble family and educated at the Sorbonne, de Broglie received his doctorate in 1924. De Broglie's doctoral thesis contains his theory of electron matter waves, later used by Erwin Schrodinger to develop wave mechanics. De Broglie has also written numerous popular works, including New Perspectives in Physics (1962).
