Charm and QCD at Cleo-III and Cleo-c

We present recent results on charm physics from CLEO-III, emphasizing QCD and hadronic structure. These include the decay $\Xi_c^0\to pK^-K^-\pi^+$ and the form factor for $D^0\to\pi^-e^+\nu_e$. We also discuss upcoming measurements with CLEO-c, including dramatic improvements in the $D^0\to\pi^-e^+\nu_e$ form factor, and glueball spectroscopy in $J/\psi\to\gamma X$.
