The field of high energy physics stands at the threshold of
uncovering the nature of electroweak symmetry breaking: the
fact that the carriers of the weak force, the W and Z bosons,
have mass while the carrier of the electromagnetic force, the
photon, does not.  Experiments at the great particle colliders
LEP, the Tevatron, and soon the LHC, will, jointly, make the
standard model of particle physics face its ultimate test.
Will the Tevatron get a glimpse of the Higgs boson before the
LHC?  Could the Higgs sector be more complex than a single
scalar?  Will we require the International Linear Collider to
complete this quest?  In this talk we will address these
questions and many more spanning four decades of research,
past, present, and future.
