BORN, MAX. Nobel prize in physics. Two typed letters signed ("Max Born" and "M. Born") to the American physicist R.S. Shankland, 3 May 1963 and 10 April 1964. Each 1 page, 4to, on printed airmail forms, each addressed and stamped on verso. BORN ON EINSTEIN AND RELATIVITY. He is grateful for Shankland's article, "Conversations with Einstein," which "I have read...with the greatest interest. You give a very lively picture of Einstein in the last period of his life. I never saw him again after 1932, and every account of his life at Princeton interests me very much..." Born corrects a point regarding "the problem of rigidity in relativity. I think that the definition given in my paper of 1909...is still correct and the only possible one, although it has the consequence that for arbitrary motion of a fixed point in a body this body can never be rigid..." The second letter comments on an article concerning the Michelson-Morley Experiment: "...I worked in Michelson's laboratory in Chicago in 1913, where I gave lectures on relativity and learned to use a g[y]rating spectroscope...My old book on relativity...has appeared...in a modernized version..." Born (1882-1970), adamantly opposed to the Hitler regime, left Germany in 1933 and taught at Cambridge and Edinburgh before returning to Germany in his retirement. (2)
