After a brief introduction to the theoretical basis of the Higgs mechanism for generating the masses of elementary particles, the exper-imental searches for Higgs particles will be summarized, from bounds at LEP to inferences for LHC. The report will focus on the Standard Model, though some central results on extended Higgs systems, as con-jectured for example in supersymmetric theories, will also be recapitu-lated. Alternative scenarios based on spontaneous symmetry breaking by novel strong interactions are adumbrated at the theoretical level.
