1902 – 1984
Paul Dirac was a British theoretical physicist and one of the principal founders of quantum mechanics and quantum electrodynamics. He formulated the Dirac equation describing relativistic electrons, predicted the existence of antimatter, and shared the 1933 Nobel Prize in Physics with Erwin Schrödinger.
