Reactor Neutrinos: Toward Oscillations

I shall sketch the history of reactor neutrino physics over five decades since the Reines-Cowan proof of neutrino existence in the late 50s, till the advent of the present era of precision reactor neutrino oscillation experiments. There are three chapters of this story: i) Exploration of possibilities of the reactor neutrinos in the 60s and 70s; ii) Looking for oscillations under the streetlamp in the 80s and 90s; iii) Exploring oscillations in detail with known (almost) $\Delta m^2_{atm}$ and $\Delta m^2_{sol}$.}
