Neutrinos are surely the most enigmatic fundamental particles in Nature. Wolfgang Pauli postulated the neutrino as an undetectable particle, however nowadays neutrinos can be detected routinely thanks to very large advanced detectors. Many of the developments in the neutrino field were triggered by the pioneering experiment of Ray Davis observing too few neutrinos from the Sun compared to expectations. Surprisingly the solar neutrino problem was caused by our incomplete understanding of the particle physics. The solution was: Neutrinos have mass and oscillate, changing from one flavor to another. It was for these findings that the Nobel Prize in Physics 2015 was awarded to Takaaki Kajita (from Super-Kamiokande Experiment) and Arthur B. McDonald (from SNO Experiment).

The talk will retrace the history of the neutrino and discoveries in the neutrino field. A particular focus will be on the discovery of neutrino oscillations. Future efforts in neutrino oscillation physics and neutrino astronomy will be discussed and their potential for more discoveries evaluated.
