We report recent results on charmonium spectroscopy and decay from the CLEO-c experiment at the Cornell electron-positron storage ring accelerator, CESR. Most of the results are based on the analysis of 54 pb-1 of luminosity collected at the ψ(2S) resonance, corresponding to 27 ψ(2S) decays. We concentrate on radiative decays of ψ(2S) and J/ψ, on two-body mesonic decay of χcJ, on hadronic decay of the hc, and on higher multipoles in the two-photon cascade ψ(2S)→γχcJ, χcJ→γJ/ψ.
