  Overwhelming experimental evidence for quarks as real physical constituents
of hadrons along with the QCD analogs of the Balmer Formula, Bohr Atom and
Schroedinger Equation already existed in 1966. A model of colored quarks
interacting with a one-gluon-exchange potential explained the systematics of
the meson and baryon spectrum and gave a hadron mass formula in surprising
agreement with experiment. The simple quark model dismissed as heresy and
witchcraft by the establishment predicted quantum numbers of an enormous number
of hadronic states as well as relations between masses, reaction cross sections
and electromagnetic properties, all unexplained by other approaches. Further
developments leading to QCD included confinement in the large $N_c$ limit,
duality, dual resonance and string models, high energy scattering systematics,
unified treatment of mesons and baryons, no exotics and no free quarks.
