"During this period I attended two sessions of the Michigan summer school at which Schwinger (1948) and Feynman (1949) described their respective reformulations of QED. Schwinger’s was deeper and more complete while Feynman’s was easier to use but at that time incomplete. One may give a feeling for the impact of Schwinger by quoting Dyson who wrote home that ”in a few months we shall have forgotten what pre-Schwinger physics was like.” Bethe at that time described this period as the most exciting in physics since the great days of 1925-30 when quantum mechanics was being discovered."

Julian Schwinger
Julian Seymour Schwinger (February 12, 1918 – July 16, 1994) was an American theoretical physicist. He is best known for his work on quantum electrodynamics (QED), in particular for developing a relativistically invariant perturbation theory, and for renormalizing QED to one loop order.
