SUPERGRAVITY AND THE QUEST FOR A UNIFIED THEORY
The 1994 Dirac Prize Lecture, delivered at the International Centre for Theoretical Physics, Trieste, on 19 April, 1994.
A recollection of some theoretical developments that preceded and followed the first formulation of supergravity theory is presented. Special emphasis is placed on the impact of supergravity on the search for a unified theory of fundamental interactions.
