59 Typed Letter Signed By Albert Einstein 85EINSTEIN, Albert. Typed letter signed. Princeton, November 3, 1942. One sheet, measuring 8-1/2 by 11 inches, typing on recto only; matted and framed with portrait. $38,000 An exceptional typed letter signed by Einstein on precursors like Johannes Kepler’s work to his Special and General Theories of Relativity, beautifully framed. The letter, on letterhead from the Institute for Advanced Study in Princeton, reads in full: “November 3, 1942. Mr. Felix W. Cartier. Laconite, Minn. Dear Sir: Since the times of Kepler one has found approximation formulaes for the mean distances of the planets from the sun. It is sure that there are not precise laws behind those approximate relations. It may be possible to understand the irregularities of this kind with the methods of statistical mechanics. But hitherto nobody seems to have been able to do so. In any case there is no analogy between such regularities and the quantum laws in molecular physics. Very truly yours, [signed] A. Einstein. Prof. Albert Einstein.” Expected fold lines. An incredible letter, scarce in its important content. Einstein’s “One And Only Intellectual Biography” 86(EINSTEIN, Albert). Albert Einstein: Philosopher-Scientist. Evanston, 1949. Octavo, original blue cloth, dust jacket. $2600 First trade edition of this collection, including the only autobiography written by Einstein, “the greatest physicist of the 20th century” (PMM). “Historians of modern science have good reason to be grateful to Paul Arthur Schilpp, professor of philosophy and Methodist clergyman but better known as the editor of a series of volumes on ‘Living Philosophers,’ which included several volumes on scientist-philosophers… to his everlasting credit, he persuaded Albert Einstein to do what he had resisted all his years: to sit down to write, in 1946 at age sixtyseven, an extensive autobiography” (Gerald Holton). Includes Einstein’s autobiographical notes in German and English; 24 descriptive and critical essays on Einstein’s work, together with Einstein’s responses; and a bibliography of his writings and index. Book fine, price-clipped dust jacket nearly so.
