  We present the first large, unbiased sample of Lyman Break Galaxies (LBGs) at
z ~ 1. Far ultraviolet-dropout (1530 A) galaxies in the Chandra Deep Field
South have been selected using GALEX data. This first large sample in the z ~ 1
universe provides us with a high quality reference sample of LBGs. We analyzed
the sample from the UV to the IR using GALEX, SPITZER, ESO and HST data. The
morphology (obtained from GOODS data) of 75 % of our LBGs is consistent with a
disk. The vast majority of LBGs with an IR detection are also Luminous Infrared
Galaxies (LIRGs). As a class, the galaxies not detected at 24 microns are an
order of magnitude fainter relative to the UV compared with those detected
individually, suggesting that there may be two types of behavior within the
sample. For the IR-bright galaxies, there is an apparent upper limit for the UV
dust attenuation and this upper limit is anti-correlated with the observed UV
luminosity. Previous estimates of dust attenuations based on the ultraviolet
slope are compared to new ones based on the FIR/UV ratio (for LBGs detected at
24 microns), which is usually a more reliable estimator. Depending on the
calibration we use to estimate the total IR luminosity, beta-based attenuations
A_{FUV} are larger by 0.2 to 0.6 mag. than the ones estimated from FIR/UV
ratio. Finally, for IR-bright LBGs, median estimated beta-based SFRs are 2-3
times larger than the total SFRs estimated as SFR_{TOT} = SFR_{UV} + SFR_{IR}
while IR-based SFRs provide values below SFR_{TOT} by 15 - 20 %. We use a
stacking method to statistically constrain the 24 microns flux of LBGs non
individually detected. The results suggest that these LBGs do not contain large
amounts of dust.
