Possibilities for detecting primaeval galaxies are reviewed. The best prospects for detection are giant elliptical galaxies, in a stage of rapid star formation about 10 to the 10th years ago. These primaeval galaxies would probably be quasi-stellar in angular size. They could have easily detectable magnitudes if the most luminous stage occurs at red shifts greater than 5, and if internal dust does not absorb most of the ultraviolet-visual light. Although it is not clear whether very young giant elliptical galaxies have yet been found, excess populations of blue galaxies in clusters (discovered by Butcher and Oemler) and in the field (discovered by Kron) are almost certainly in early stages of active star formation.
