Unusual handwritten manuscript fragment in German, unsigned, penned by Albert Einstein in the corner of an envelope panel addressed to him at Princeton, 10 x 4.5, postmarked June 7, 1948. In black ink, Einstein writes a draft of most of the final paragraph of his article, 'Relativity: Essence of the Theory of Relativity,' published in 1948 in the American People's Encyclopedia. A translation, as it was published, has been written below in another hand: "while it leads to a well-defined theory of the gravitational field it does not determine sufficiently the theory of the total field (which includes the electromagnetic field). The reason for this is the fact that the general field laws are not sufficiently determined by the general principle of relativity alone." In fine condition, with scattered light creasing, and a very short tear to the top edge. An important autograph in which Einstein implicitly states why he spent so many of his final years searching for a Unified Field Theory.
