Knollwood Saranac Lake N. Y. 23 August 1940 Dear Nathan, On account of a letter I wrote to him, Dr. Walter Rosenblith, Cold Spring Harbor, will probably contact you regarding an endangered refugee in unoccupied France. You do not need to read the enclosed copy of my letter to him now, only when the man writes to you. Come soon, bring warm clothes with you, and cordial greetings From your A. Einstein. [TLS]
