The quest to define early galactic nucleosynthesis has drawn on the efforts of many observers and theoreticians over the past few decades. Significant insights on galactic halo chemical evolution have been revealed through the use of high resolution, high S/N spectroscopy to determine abundances in stars with metallicities ranging over three orders of magnitude. In the process, many galactic nucleosynthesis ideas that were firmly established only a decade ago now are either disproved, or are currently under challenge, or are weighed down with multiple known exceptions. The galactic halo has a rich chemical history, and we are just beginning to understand just how much work still remains before we can decipher its evolution.
