Einstein and Grossman’s papers of 1913 “contained the first attempts toward a generalized theory of relativity, using new mathematical tools, and gave full expression to Einstein’s earlier physical insights.” -Mehra Jagdish
EXTREMELY RARE AUTHOR’S OFFPRINT (“Überreicht von den Verfassern”) IN ORIGINAL WRAPPERS OF THE FIRST PRINTING OF EINSTEIN AND GROSSMANN’S FURTHER DEVELOPMENT OF THE CRITICAL “ENTWURF” THEORY OF 1913.
“Einstein returned from Prague to Zurich in the summer of 1912. He had by then already formulated the fundamental physical principles of the general relativity theory of gravitation, and was now searching for their mathematical structure. At the E.T.H. [the Swiss Federal Institute of Technology in Zurich], where he now returned as professor of theoretical physics, Einstein met again his old fiend and former fellow student Marcel Grossmann, who was now a professor of mathematics and his colleague. With Grossmann, and under his guidance, Einstein studied the mathematical literature, especially the theory of invariants and the absolute differential calculus of Chirstoffel, Ricci, Levi-Civita and others. Einstein developed the mathematical structure of his theory jointly with Grossmann, and in his celebrated paper on the general theory of relativity in 1916 he acknowledged the help which his friend had given him. It was Grossmann’s help which had, Einstein said, ‘spared me not only the study of the relevant mathematical literature, but who [Grossmann] also assisted me in searching for the field equations of gravitation.’ This study of mathematical literature and the search for the proper mathematical tools led to several joint papers with Grossmann during Einstein’s all too brief stay in Zurich. These papers contained the first attempts toward a generalized theory of relativity, using new mathematical tools, and gave full expression to Einstein’s earlier physical insights” (Jagdish, The Golden Age of Theoretical Physics).
The first of Einstein’s papers to present his collaborative work with Grossmann, the famous “Entwurf” paper, appeared in the summer of 1913; the present paper, based on a lecture given on September 9, 1913, to the 96th annual meeting of the Swiss Society for Natural Sciences in Frauenfeld, provides further details on the new generalized theory of relativity. The published paper contains more mathematics than in the given lecture. Weil 57.
