We present spectroscopic observations of galaxies lying within 1' of QSO J2233-606 in the Hubble Deep Field South (HDF-S). Several are found to be coincident in redshift with absorption-line systems seen in the HST J2233-606 spectrum. We detect a new z_em=1.336 QSO with I=20.8 at a projected angular separation of 44.5" (or ρ=200h^–1kpc; q₀=0.5) from J2233-606. This QSO pair is an ideal target for QSO environment studies. Indeed, strong HI Lyα and Lyβ absorptions are seen at z_abs=1.3367 in the J2233-606 spectrum. The bright spiral galaxy (J2233378-603324), projected at 4.7" from J2233-606, is at z=0.570 (thus ρ=18h^–1kpc). Absorption is seen in the Lyman series at the same redshift but the weakness of the Lyman break implies N(H I)<10¹⁷cm^–2.
