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. He defied his family's wishes and left the navy in 1904 to pursue a scientific career, and 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. In the NATO phonetic alphabet, X-ray represents the letter X.
