Unsigned handwritten partial manuscript, in German, 8.25 x 5, dating from late 1928 to early 1929. This is a portion of an unpublished paper dealing with the Unified Field Theory and Hamilton’s Principle. This is the bottom portion of a page written in Einstein’s hand. In early 1929, Einstein published two articles on the Unified Field Theory in the session reports of the Prussian Academy of Sciences, which at the time made international news. This portion may be the only part of the article that survived, perhaps earlier than the two. As in the two published articles, Einstein here acknowledges the help of Polish mathematician Hermann Muntz, “for the solution to this dilemma I thank Mr. Muntz, for his remarks according Cauchy’s theorem.” Manuscript also bears two intriguing mathematical formulas. In fine condition, with light creasing to lower left corner, missing lower right corner tip and small chip to top and left edges. Auction LOA John Reznikoff/PSA/DNA and RRAuction COA.
