Abstract

Early-type dwarf (dE) galaxies exhibit a puzzling variety of observable properties. Are they at all a single class of objects? Could some of them be “primordial” galaxies, while others were created by environmental processes? Here I provide a brief overview of early-type dwarfs, focusing on galaxy clusters, where dEs are the dominant galaxy population by number.
