Nobel Prize Recipient. Louis-Victor Pierre Raymond de Broglie was a French physicist, who became recognized professionally after receiving the 1929 Nobel Prize in Physics. According to the Nobel Prize committee, he received the coveted award "for his discovery of the wave nature of electrons" and his groundbreaking contributions to the quantum theory along predicting the wave nature of electrons. Born into a French wealthy, aristocratic household, his parents were Victor and Pauline dud de Broglie. He and his older brother Maurice broke with their family's traditions to become scientists. His brother established a laboratory in the family's mansion, researching x-rays. After having a privileged early education, he studied history in 1910 before changing his major to science and graduating with a degree in physics in 1913. His education was halted as he served in the French Army for the entire World War I. In 1924 at the Faculty of Sciences at Paris University, he wrote a thesis to earn his PhD degree, which became known as the "de Broglie hypothesis." His thesis was forwarded to Albert Einstein, who was greatly impressed, yet starting in 1927, it would be other scientists that proved his hypothesis true, American scientists Clinton Davisson and Lester Germer and the British scientist, George Thomson. After receiving his PhD, he remained at the Sorbonne. In 1928, he became professor of theoretical physics at the newly founded Henri Poincaré Institute, where he taught until his retirement in 1962. After World War I ended, he became an adviser to the French Atomic Energy Commissariat. Besides the Nobel Prize, he was a foreign member of the British Royal Society, French Academy of Science, received the Kalinga Prize in 1952, and published several other papers. In 1740 Louis XIV had conferred the hereditary title of "duc" on the head of the family. After his older brother Maurice died in 1960, he inherited the title of the 7th duc de Broglie. He also inherited the title of "Prinz" for the service his ancestor did during the Seven Year War from 1756 to 1763. Since he never married, a distant cousin, Victor-François de Broglie (1949-2012) (261791291) inherited these titles upon his death.
