Do you know what was LENIH and what it has become now?

In this paper, the beginnings of the Laboratory of Nuclear Spectroscopy and Hyperfine Interactions (LENIH) at the Department of Physics of the National University of La Plata and the evolution of the principal ideas involved and the main goals achieved are reviewed. Special attention is devoted to the relationships between the LENIH members and the international scientific community through the years, since they have been fundamental for the existence and development of the applications of hyperfine interactions in Solid State Physics at La Plata. A scheme of the socio-political situation in which the LENIH grew and could consolidate its actual position as well as the diversified research lines developed at present are also described.
