During his Nobel Prize banquet speech, 2013 physics laureate Peter Higgs reflected on the decades of research – and the many individuals – whose work contributed to understanding the origin of subatomic particle mass. Among those whose insights shaped this achievement was Robert Brout, whose collaboration with François Englert laid the theoretical foundations of what is now known as the Brout–Englert–Higgs (BEH) mechanism.
