An accurate measurement of the primordial value of D/H would provide a critical test of nucleosynthesis models for the early universe and the baryon density. I briefly summarize the ongoing HST observations of the interstellar H and D Lyman-α absorption for lines of sight to nearby stars and comment on recent reports of extragalactic D/H measurements.
