Associated production of Higgs bosons with top-antitop pairs at hadron colliders, {ital pp}{r arrow}{ital Ht{bar t}X}, is examined. By tagging on an isolated secondary lepton, {ital e} or {mu}, from the {ital t} or {ital {bar t}} decay, discovery of an intermediate-mass Higgs boson, {ital m}{sub {ital H}}{congruent}80--150 GeV, via {ital H}{r arrow}{gamma}{gamma} is rendered feasible at the Superconducting Super Collider (SSC) ({radical}{ital s} =40 TeV). Allowing a factor-of-0.4 signal reduction for isolation cuts and selection efficiencies leaves about 21 events per SSC year for {ital m}{sub {ital H}}{congruent}80--130 GeV, and somewhat less for 130--150 GeV, above an anticipated small background. At the CERN Large Hadron Collider ({radical}{ital s} =16 TeV), the cross section is reduced by about a factor of 1/8.
