Damped Lyman-alpha absorption systems contain the bulk of the neutral gas in the Universe in the redshift range z = 0.5 - 5 yet the nature of the galaxies responsible for the absorption is not well understood. Only recently have we found more than a handful of damped absorbers at redshifts z < 1.5. Using the FIRST Bright Quasar Survey {FBQS}, with over a 1000 quasars, we have undertaken a survey to build a complete picture of he nature of the galaxies responsible for damped Lyman-alpha absorption systems at z 1 and to double the sample size at this redshift. The FBQS provides the first large, well defined, unbiased sample to use in these studies. STIS spectroscopy of candidate damped absorption systems at z < 1.7 is required to accurately measure their HI column densities and confirm which are damped. A complementary ground-based imaging and spectroscopic program is underway at Keck Observatory to identify and characterize the galaxies associated with the absorption systems.
