The discovery and analysis of metal-poor stars lead to insight into conditions when the Universe and Galaxy were young. We present the rationale for studying such objects (which become progressively rarer at lowest abundance), with a description of their systematic discovery, culminating in the recent analysis of two objects having [Fe/H] < -5.0. We discuss the Metallicity Distribution Function of metal-poor stars and the abundance patterns of several elements, from Li through to the heavy-neutron-capture elements. Relatively few (~50) stars with [Fe/H] < -3.0 have been analyzed at high spectral resolution and high signal-to-noise. As one proceeds to lowest abundance one finds astounding overabundances of some or all of the CNO group and the lighter elements. This diversity among the most metal-poor stars has yet to be fully understood.
