The original idea of the wave-particle duality was from Louis de Broglie.
He conceived of electrons, for example, as very localized singularities that were "propelled", so to speak, by an underlying energy "wave" that he named a "pilot wave".

Article The reinterpretation of wave mechanics
When correlated with the magnetic aspect of energy, a recent analysis seems to make obvious that what he describes as a pilot wave was in fact the momentum energy that defines the velocity of a localized electron in motion.
This recent analysis discusses the relation between the momentum energy of the electron that de Broglie related to his pilot wave and its relation to electromagnetism:
