Descrizione

True author's presentation offprint in the original wrappers, of Einstein's obituary for Austrian physicist and philosopher Ernst Mach. - Edition: Mach is particularly known as influential philosopher of science for his contemporaries. Through his criticism of Newton's theories of space and time he for instance foreshadowed Einstein's theory of relativity. - Condition: Corners and margins of wrappers with some very small faults, cover slightly water-stained, paper minimally foxy, otherwise solid copy. - Rarity: Present copy is imprinted „Überreicht vom Verfasser“ (presented by the author) on the upper right corner of the first page, which indicates it's utmost rarity, as author's presentation offprints of Einstein papers, from any journal or any period, were printed in a small print run for the use of the author only. ABPC (1973ff.) and APO (1988ff.) show no record at all. - Reference: Collected Papers, vol. 6, 29; Schilpp-Shields 96; Weil 89.
