Louis de Broglie

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 aban…
