  We review many of the contributions of the CLEO experiment to tau physics.
Topics discussed are: branching fractions for major decay modes and tests of
lepton universality; rare decays; forbidden decays; Michel parameters and spin
physics; hadronic sub-structure and resonance parameters; the tau mass, tau
lifetime, and tau neutrino mass; searches for CP violation in tau decay; tau
pair production, dipole moments, and CP violating EDM; and tau physics at
CLEO-III and at CLEO-c.
