    Description

    Albert Einstein Autograph Letter Signed "A. Einstein." One page, 8.5" x 11", no place; February 3, 1950. Addressed to his assistant Ernst Straus, and written in German. Einstein writes of the success of confirming his Generalized Theory of Gravitation, which expanded the application of his General Theory of Relativity, and he even handwrites the pertinent equations. A translation of the letter reads in full:

    "Dear Mr. Strauss! Your detailed letter, which made me very happy, arrived just now. I am innocent of all the clamor about the theory. However, it really does constitute immense progress. You see, I was successful in proving compatibility for the (stronger) system [handwritten equations]

    This is indeed the excellent generalization of the gravitational equations. (You will recall that we believed to have convinced ourselves that this was impossible!) I am sending you a proof of the paper that is being published as an appendix of my little book on relativity. After you have seen this thing, please pass it on to my old friend and assistant [Cornelius] Lanczos, whom I want you to meet. You will enjoy knowing him. Please give him my best and, for the time being, thank him on my behalf for his most recent letter. Please excuse my brevity. You do know how things are here with us. Cordial greetings to both of you and the cat."

    An extraordinary letter by Einstein expressing satisfaction at his success in making forward progress to our understanding of the universe. Although his attempts to unify differing theories of gravity and relativity were discounted after his death, many now believe that he has since been vindicated with new discoveries, including the "strong force" of particle physics.

    Condition: Flattened mail folds with light edge toning. Minor chipping along the top edge. Clear and bold signature.
