Three quarters of a century ago, in his paper on "Quadrupole and dipole γ-emission from nuclei" A.B. Migdal introduced the concept of quantum collective excitation modes into nuclear physics, predicting the phenomenon of giant dipole resonance (GDR). GDR research has had an enormous influence on the formation of modern concepts relating to the dynamics of nuclei. This article, after a brief analysis of the paper of A.B. Migdal, traces the history of theoretical and experimental study of the GDR. New forms of GDR and analogues of GDR in non-nuclear microsystems are mentioned.
