First Editions, Offprint Issues. Pauli and Solomon's paper examines Einstein and Mayer's attempt at a unified field theory of the gravitational and electromagnetic fields, which the latter two authors had published in their paper "Einheitlichliche Theorie von Gravitation und Elektrizität" (1931). Pauli had been working a new collaborator, the Parisian physicist Jacques Solomon, and in the winter of 1931-32 he put Solomon onto the unified field theory problem. Solomon completed a paper on the subject, which he submitted to the Journal de physique et le radium under both his and Pauli's names; however, when Pauli asked his assistant Hendrik Casimir to read a proof of the paper, Casimir found that most of the essential formulae were wrong. "Pauli cabled to Paris that the paper had to be rewritten. But the editor of Journal de physique, Jean Langevin, who happened to be Solomon's brother-in-law, told Pauli with apologies that the second proofs had not come back in time. So the paper ‘The unified theory of Einstein and Mayer and the Dirac equations' appeared uncorrected . . . Therefore Pauli decided to write a second paper with the same title, and Solomon had the benefit of two publications with the master" (Enz, No Time to be Brief: A Scientific Biography of Wolfgang Pauli, pp 265-266).
