  At CLEO, charmonium spectroscopy is pursued both thorugh e+e- annihilation
data taken in the Upsilon region and more recently at psi(2S). A nmber of first
observations (eta_c', h_c, pi and K form factors) have been made, and numerous
high precision measurements have been made in radiative and hadronic decays of
charmonium resonances. A brief report of these contributions is presented.
