Abstract
The invention of partons by Richard Feynman was one of his most important contributions to modern particle physics. The parton model appears at a critical moment characterized by the polarization of particle physics in two opposing schools of thought: on the one hand, the so called nuclear democracy, postulating that all hadrons are equally fundamental and on the other hand a school of thought that was starting to form around the idea of quarks and their use at first, not as fundamental constituents of hadrons, but rather as mathematical entities reflecting the internal symmetries of an underlying quantum field theory (QFT) for the strong interaction, at that point still unknown. The parton model rapidly became an important tool in the construction of this QFT, named Quantum Chromodynamics, helping to promote quarks from mathematical entities to fundamental constituents of the hadrons.
