‎First edition of Feynman's very first paper on quantum electrodynamics (QED), being one of Feynman's most important publications which pre-dates his work on Feynman diagrams by a year. Feynman, Schwinger and Tomonago shared the 1965 Nobel Prize in Physics ""for their fundamental work in quantum electrodynamics, with deep ploughing consequences for the physics of elementary particles"".‎
