Evolution of Normal Galaxies: HST Morphologies and Deep Spectroscopy

. I review progress in understanding the evolution of normal field and cluster galaxies through the combination of HST imaging and ground-based spectroscopy. These data suggest that the bulk of the star formation producing the present-day galaxy population occurred at accessible redshifts, z !2. Furthermore, a surprising amount of the detailed processing that shaped the Hubble sequence and morphologydensity relation occurred surprisingly recently. The stage is thus set for a concerted attack on these questions with the present generation of 8-10 metre large telescopes. An important step forward will be the development of efficient survey techniques for the systematic exploration of the z ?1 Universe. Some possible approaches are briefly discussed. 1 Introduction and the Role of Instrumentation These are exciting times in the fields of observational cosmology, galaxy formation and evolution. The rate of publications on bulletin boards like SISSA is one (albeit possibly unreliable) indi..
