The Prelude to the QCD Revolution

Abstract:
The is the historical talk I gave at the \50 Years of QCD" conference at UCLA last September. I describe the revolution in particle physics between 1962 and 1972 that led up to the formulation of QCD and the discovery of asymptotic freedom in 1973. The talk focuses on James Bjorken's seminal 1966 paper on the \Applications of the Chiral U(6)U(6) Algebra of Current Densities", the discoveries that led up to it, the confusion in the theory community that ensued, and the emergence of the quark-gluon paradigm that became QCD.
