The recent discovery at the LHC of a new fundamental particle has

generated a significant amount of excitement around the globe -- an

excitement unmatched in particle physics since the discovery of the

top quark in 1995. Given its observed decay channels, its mass and a

handful of its properties, indications are that this new particle

could be the long-sought Higgs boson, purported to be the linchpin in

understanding the imposition of mass to the fundamental particles. But

much remains to be known about this new particle -- it could be the

Higgs boson predicted by the standard model or it could be something

more exotic.  Characterization of this new particle must be done in

many different channels; its interactions with the top quark will

play a vital role in this endeavor. Herein I describe the importance

the top quark will play in studies of this new particle, and

describe in detail one particularly important channel in the

characterization effort: the search for production of the Higgs

in association with top-quark pairs at CMS.
