Originally proposed as a theoretical construct in 1964 to explain how an underlying symmetry in a Lagrangian may be hidden in the ground state, it soon became the key stone of the Standard Model. In the years since the Standard Model has been remarkably successful in explaining experimental results and yet, the Higgs boson itself has remained elusive until the advent of the LHC. The discovery at the LHC of the Higgs boson has prompted the awarding of the 2013 Nobel prize to Peter Higgs and Francois Englert.

In this talk I will briefly review the construction of the Higgs model and the history of the idea. I will then discuss the strong evidence for the Higgs boson's discovery at the LHC. I will finish off by discussing ways that the Higgs may be "used" to look for evidence for the next layer of physics which lies beyond the Standard Model.
