A question stood out for decades: Are neutrinos massive like their seemingly inseparable electron siblings? It took almost seventy years to obtain the positive answer. I review here past and present efforts to probe the origin of neutrino mass and show that this is deeply related to the fundamental question of left-right symmetry in nature. This ongoing story will take us from the beginnings of elementary particle physics all the way to the frontiers of the Large Hadron Collider.
