  Dwarf ellipticals have the lowest stellar densities of any galaxies, but
paradoxically are most common in the densest regions of the universe, and are
especially frequent in rich clusters of galaxies. Simple estimates suggest that
low luminosity dwarf ellipticals should be subject to substantial tidal heating
in rich clusters if most of their mass is in the form of normal stars. We have
therefore undertaken a program to image dwarfs in clusters with the 3.5-m high
performance WIYN, ARC and smaller, wide field telescopes. Our objectives
include testing for evidence of tidal disruption in the form of asymmetries and
searching for evidence of recent star formation which might be associated with
the production of elliptical dwarfs from in-falling field galaxies.
