Information About

Maurice, 6th Duc De Broglie




He was born in Paris , the son of Victor, 5th Duc De Broglie .
In 1901 , he was married to Camille Bernou De Rochetaillée ( 18881966 ) in Paris. They had one daughter, Laure, born on 17 November 1904 , who died, aged six, on 12 June 1911 .
He acceded to the title of Duc De Broglie on his father's death in 1906 . He died on 14 July 1960 in Neuilly-sur-Seine ( Hauts-de-Seine ). His only child having died almost a half-century before, his brother Louis succeeded him as duke.

Having graduated from naval officer's school, Maurice de Broglie spent nine years in the French Navy , serving on a gunboat at Bizerte and in the Mediterranean Squadron. While serving, he became interested in physics, and began doing research on Electromagnetism . Broglie defied his family's wishes and left the navy in 1904 to pursue a scientific career. He studied under Paul Langevin at the Collège De France in Paris , receiving his Doctorate in 1908 .

Broglie made advances in the study of X-ray Diffraction and Spectroscopy . During the First World War , he worked on Radio communications for the navy. After the war, he resumed his research at a large laboratory in his home. He occasionally collaborated with his younger brother Louis , who followed his professional lead and was training as a physicist, and they coauthored a paper in 1921 . After Louis de Broglie's rise to prominence in the 1920s , building on some of their shared research, the elder Broglie physicist continued his own research. While Louis was primarily a theoretician, Maurice himself was always the experimental physicist ''par excellence.''

He became a member of the Académie Des Sciences in 1924 , and in 1934 was elected to the Académie Française , replacing the historian Pierre De La Gorce . In 1942 he succeeded his mentor, assuming Langevin's chair in physics at the Collège de France. He was also elected to the Royal Society Of London on 23 May 1940 , having received the Royal Society's Hughes Medal in 1928 .
