a French physicist, proposed the theory explaining the wave properties of electrons in 1924. His work greatly advanced the early understanding of quantum theory, the study of the parts of the atom and their behavior. In 1924, existing quantum theory stated that light waves sometimes behave like particles. Using mathematical logic, de Broglie reasoned that the particles, in turn, have wavelike properties. De Broglie's theory of "matter waves," which sent physicists everywhere thinking in new and unexpected direction, became the foundation for a new field of study-wave mechanics.
Proof of de Broglie's theory came in 1927 in experiments by physicists Clinton j. Davisson and Lester Halbert Germer, working with slow electrons, and by G. P. Thomson, working with fast electrons. For his vision, de Broglie received the 1929 Nobel Prize for physics and the Henri Poincare Medal of the Academie des Sciences. After receiving a degree in history from the Sorbonne in 1909, de Broglie took up his real interest, receiving a "license" in science from the University of Paris in 1913. During World War 1(1914-1918), he served in the radiotelegraph branch of the French Engineering Corps at the wireless station of the Eiffel Tower. Afterward, de Brogue resumed his scientific study at his brother's physics laboratory. Born into a noble French family, de Broglie was known as Prince Louis Victor Pierre Raymond de Broglie throughout his life. His ancestors served French kings in war and diplomacy from the time of Louis XIV. De Broglie's brother Maurice, also a physicist, was known for his research in nuclear physics, X rays, and radioactivity. While pursuing his lifelong interest in research, de Broglie taught theoretical physics at the Henri Poincare' Institute in Paris. In 1943, he founded the Center for Studies in Applied Mathematics at the institute to help physicists and mathematicians work together. Along with his brother, de Broglie was named to the French High Commission on Atomic Energy in 1945, and he also was a member of the Academie Francaise, which oversees French language and literature. De Broglie was elected to a number of prestigious international scientific societies and was appointed permanent secretary of the French Academy of Sciences in 1942.
