Louis de Broglie
1892–1987 (age 95)
Biography
Physicist Louis de Broglie transformed modern science by proposing that particles carry wave-like properties, a bold insight that reshaped quantum mechanics and earned him the Nobel Prize.
He spent later years guiding younger physicists and reflecting on the philosophical implications of his theory, and his grave at Neuilly-sur-Seine Old Communal Cemetery marks the rest of a thinker who united rigor with humility.
