The Standard Model of particle physics is remarkably successful, but requires a new particle, known as the Higgs boson, which has never been seen. Proposed in 1964 this is now generally assumed theoretically, and the hunt is one to find it.This search has been a defining feature of high-energy collider studies for twenty years, and is a major reason for the construction of the LHC at CERN. The data collected in 2011 have already told us a great deal about where the Higgs boson could be hiding. These results will be reviewed and prospects for completing the search outlined.
