Tht development of the concept of subatomic particles is traced from the atom to the mesons and nucleons. The roles of the quantum theory and of the concept of symmetry are discussed, the significance of the research into subatomic particles for the physics is stressed. Resume L'evolution du terme particule elementaire est analysee, depuis I'atome jusqu'aux mesons et aux nucleons. Le roIe de Ia theorie des quanta ainsi que Ie terme symetrie font I'objet d'une discussion, tandis que I'auteur souligne l'importance de Ia recherche fondamentale relative aux particules elementaires pour Ia...
