Louis de Broglie is mainly remembered for his contribution regarding the wave-particle duality and the expression that relates linear momentum and wavelength in the development of Quantum Theory, contributions given in the period 1922–1924. However, little is said about his posture and critical activity to related interpretations of Niels Bohr’s Complementarity, and his proposal of new bases for an alternative quantum theory, with a realistic and deterministic character. Thus, in order to present original historical texts and contribute to the rescue of Louis de Broglie’s ideas, we present a commented translation of the article “The Hidden Thermodynamics of Particles”, published in 1964, where de Broglie summarizes his theoretical proposal and presents two important results, namely: that the path of least action taken by a particle is the one that maximizes the entropy of the subquantum medium; and that transition states in an atom would have a lower entropy than steady states, thermodynamically justifying why steady states are more likely to happen.
