First Edition in English, Offprint Issue (a Dutch version appeared the same year). The Dutch physicist Adriaan Fokker, a student of Lorentz, made several contributions to both special and general relativity, collaborating with Einstein in 1914 on a paper on Nordström’s theory of gravitation and publishing a summary of the Einstein-Grossmann theory of gravitation the following year. The present paper, Fokker’s first on general relativity since the Einstein-Grossmann paper, “gave a reformulation and an extension of earlier work by Lorentz on the Hamiltonian formulation of general relativity. Notable in this paper was a derivation of the contracted Bianchi identities (as a consequence of the variational principle) and a discussion of its implications for the field equations” (Kox, p. 42).
Fokker presented this copy to Niels Bohr, winner of the Nobel Prize for physics in 1922 for his fundamental contributions to our understanding of atomic structure and quantum theory. A.
