This lecture is about the low energy part, i.e. for energies in the $(γp)$ center-of-mass mainly up to the $Δ(1232)$ resonance region. I review the concept of Generalized Polarizabilities of the Nucleon, and the experiments dedicated to their measurement.16 pages, 8 figures. lecture given at the Erice School "Lepton Scattering and the Structure of Hadrons and Nuclei," Erice, 16 - 24 Sept. 2004; to appear in "Progress in Particle and Nuclear Physics"High Energy Physics - Phenomenologytext
