Nobel Prize in Physics 1990 "for their pioneering investigations concerning deep inelastic scattering of electrons on protons and bound neutrons, which have been of essential importance for the development of the quark model in particle physics" : Jerome I. Friedman, Henry W. Kendall and Richard E. Taylor

Lectures on "Deep inelastic scattering" Prof. R. Taylor : "in the early years" Prof. H. W. Kendall : "experiments on the proton and the observation of scaling" Prof. J. I. Friedman : "comparisons with the quark model
