TLS, one page, 5.5 x 8.5, The Institute for Advanced Study letterhead, November 20, 1956. Letter to Alfred Berger, in full: "Your letter of July 29th was sent on to us by Princeton University, since Einstein was a member of the Institute for Advanced Study, which is not formally connected with the University. We regret that we have had to adopt a policy of not acquiring further portraits of Einstein." In very fine condition. Ultra-desirable correspondence from Oppenheimer with reference to his influential friend and colleague Albert Einstein, who he later described as 'the greatest of our time.'
