EINSTEIN, Albert (1879-1955). Typed letter signed ("Albert Einstein") to Professor Alfred Landé, Princeton, New Jersey, 28 December 1935.

In German. Two pages, 215 x 275mm; Einstein's blindstamped stationery; with transmittal envelope.

Einstein writes to a fellow physicist on the theory of relativity. Landé (1888-1976) was a Professor at Ohio State University who would become known for his contributions to quantum theory, and here Einstein discusses Landé's take on the general theory of relativity: "If one seeks to consistently think through a similar point of view by taking seriously your comparison with the general theory of relativity, then one has to regard both conceptions merely as different descriptions of the same event ... It would be nice if you could tell me your opinion on this point" (translated). Landé published Principles of Quantum Mechanics two years later in 1937, followed by Quantum Mechanics in 1951, and Foundations of Quantum Theory: A Study in Continuity and Symmetry in 1955. Provenance: Sotheby's, 17 November 1988, lot 194.
