TLS in German, signed "A. Einstein," one page, 8.5 x 11, October 8, 1952. A letter recommending the work of Dr. Paul Rosenstein, in full (translated): "Professor Paul Rosenstein gave me an insight into the content of his autobiographical book. The episodes and circumstances described in it are, in my opinion, a rather considerable contribution to the cultural history of Germany and the German Jews in this century. It is the work of an unprejudiced, understanding and benevolent man." In very good condition, with overall creasing, and light toning along intersecting folds.Rosenstein was a well-established German-Jewish urologist and head of the surgical department of the Berlin Jewish Hospital, a position he held until 1938. In 1940, Rosenstein fled Nazi Germany for Brazil via New York, and seems to have practiced there for the rest of his life. Although there is no specific evidence that Einstein aided Rosenstein in his immigration attempts, he frequently used his name to sway officials and help Jewish refugees secure the paperwork needed for residency in other countries, including Brazil. A nice association between Jewish scientists who fled Germany for the safety of the Americas during World War II.Format: TLS
