Tom Kibble (GHK) at CERN - "Genesis of Electroweak Unification and the Higgs" (slides and audio)

Tom Kibble gives a historical account of the developments leading up to the unification of weak and electromagnetic interactions, as he saw them from his standpoint in Imperial College London.
He describes the state of physics in the 1950s, his work with Guralnik and Hagen, the aim of finding a unified theory of various interactions, the obstacles encountered in trying to unify the weak and electromagnetic interactions, and their eventual resolution, with a brief discussion of the later history culminating in the discovery of the Higgs boson in 2012.
