"During the Symposium on the Past Decade in Particle Theory at the University of Texas at Austin in April 1970, I had occasion to bring Dirac and Feynman together for a discussion at dinner. Dirac told Feynman that the relativistic quantum electrodynamics in its present form was an ugly theory, and before tackling the more difficult problems of elementary particle physics 'one must try to solve the problems of quantum electrodynamics. Electrodynamics is something we know most about, and we must find a consistent theory of it rather than get rid of the infinities in an arbitrary manner.' Feynman agreed with Dirac."
