The history of neutrinos, 1930–1985. What have we learned about neutrinos? What have we learned using neutrinos?

Abstract An attempt to remember some of the main events which highlight the evolution of our knowledge of the neutrinos and their properties, the “families” of particles, a few of the very interesting persons who contributed to this progress, as well as the contribution of neutrino beam experiments to the validation of the electro-weak and quantum-chromo-dynamic theories, and the structure of the nucleon.
