description: "He proved that matter behaves like a wave — electrons, atoms, everything solid ripples through space the way light does. The idea sounded like philosophy until experiments bore it out, handed him the Nobel in 1929, and gave quantum mechanics the mathematics it still runs on."

# bio (long form, separated for readability)
bio: |
  Louis Victor Pierre Raymond, 7th Duc de Broglie, was a French theoretical physicist and aristocrat who in his 1924 Ph.D. thesis postulated that electrons have wave nature and all matter has wave properties — the de Broglie hypothesis, a pillar of wave-particle duality. Experimental confirmation came in 1927, earning him the Nobel Prize in Physics in 1929 and George Paget Thomson and Clinton Davisson the same prize a decade later. Erwin Schrödinger used de Broglie's wave theory to build wave mechanics; de Broglie himself presented the pilot-wave concept at the 1927 Solvay Conferences, then abandoned it until David Bohm revived the idea in 1952, prompting de Broglie to return in 1956 with a new version blending Bohm's work and Jean-Pierre Vigier's. He became the sixteenth member of the Académie française in 1944, served as Perpetual Secretary of the French Academy of Sciences, and was the first high-level scientist to call for a multi-national laboratory — the proposal that led to CERN.
