The physics of the strong interactions always has been tightly connected to the study of nucleons at shorter and shorter distances. The measurement of the anomalous magnetic moments of the proton and neutron in 1933 and 1939 made clear that nucleons are no elementary particles. During the 1950ies the Hofstadter experiments revealed the charge distributions inside nucleons at scales Q ≃ 0.5 ·M N...
