Observations of the high redshift Universe, interpreted in the context of a new generation of computer simulated model Universes, are providing new insights into the processes by which galaxies and quasars form and evolve, as well as the relationship between the formation of virialized, star-forming systems and the evolution of the intergalactic medium. We describe our recent measurements of the star-formation rates, stellar populations, and structure of galaxies and protogalactic fragments at z~2.5, including narrow-band imaging in the near-IR, IR spectroscopy, and deep imaging from the ground and from space, using HST and ISO.
