Francois Englert (born 1932), Belgian theoretical physicist, at the Higgs boson discovery announcement, 4th July 2012, at CERN (the European particle physics laboratory). Data collected by the CMS (Compact Muon Solenoid) and ATLAS (a torodial LHC apparatus) experiments at the LHC (Large Hadron Collider) at CERN have shown a new particle at around 125 giga electron volts (GeV). Further analysis will determine if the particle is the long sought for Higgs boson, a fundamental particle that is thought to give other particles mass. Englert, along with Peter Higgs and Robert Brout, explained how the Higgs field confers mass on other particles through their interaction with it. This is known as the Brout-Englert-Higgs mechanism.
