EINSTEIN ALBERT: (1879-1955) German-born theoretical physicist, Nobel Prize winner for Physics, 1921. A very fine, rare autograph Manuscript Signed, A. Einstein, two pages (feint rule graph paper), 4to, n.p., n.d. The working manuscript, in ink and pencil, features numerous scientific calculations in Einstein’s hand, with just a few words (including ‘rule’) alongside some of the calculations and with the letters R, G, A & B appearing regularly. Signed in ink with his name alone to the lower left corner. Whilst Einstein clearly created many such pages of scientific formulae during his career, they remain highly sought after by collectors, and signed examples are of exceptional rarity, this example having been presented to a family friend. Some very light, extremely minor age wear and one small, neat tear to one edge, otherwise VG
