  Weak boson fusion promises to be a copious source of intermediate mass Higgs
bosons at the LHC. The additional very energetic forward jets in these events
provide for powerful background suppression tools. We analyze the subsequent H
-> tau tau -> e mu pTmiss decay for Higgs boson masses in the 100-150 GeV
range. A parton level analysis of the dominant backgrounds demonstrates that
this channel allows the observation of H -> tau tau in a low-background
environment, yielding a significant Higgs boson signal with an integrated
luminosity of order 60 fb^-1 or less, over most of the mass range. We also
restate a No-Lose Theorem for observation of at least one of the CP-even
neutral Higgs bosons in the MSSM, which requires an integrated luminosity of
only 40 fb^-1.
