‎First printing of Dirac's paper, a later publication of his speech to the New York Meeting of the American Physical Society in early 1959 in which he applies the Hamiltonian form of gravitational theory to Einstein's general relativity. Dirac made fundamental contributions to the early development of both quantum mechanics and quantum electrodynamics. He shared the Nobel Prize in physics in 1933 with Erwin Schrödinger, ""for the discovery of new productive forms of atomic theory.""‎
