  We present new photometric and spectroscopic data for the galaxies in the
compact group known as Stephan's Quintet. We find the strongest evidence for
dynamical perturbation in the spiral component NGC7319. Most of the damage was
apparently caused by nearby NGC 7320C which passed through the group a few
times 10(^8) years ago. NGC7318B is a spiral galaxy that shows evidence
consistent with being in the early stages of a collision with the group.
NGC7317 and 18A are either elliptical galaxies or the stripped bulges of former
spiral components. They show no evidence of past or present merger activity but
are embedded in a luminous halo which suggests that they are interacting with
the other members of the group. The low redshift galaxy NGC7320 is most likely
a late type, dwarf spiral projected along the same line of sight as the
interacting quartet.
