BBCA 1939 letter from Albert Einstein warning of the "calamitous peril" to Jews posed by the Nazis has been sold at auction for nearly $14,000 (£9,000).
Einstein himself fled Germany for the US when Hitler came to power in 1933.
"It must be a source of deep gratification to you to be making so important a contribution toward rescuing our persecuted fellow-Jews from their calamitous peril and leading them toward a better future," he wrote. Dated 10 June 1939, it has Einstein's embossed Princeton University address and the original mailing envelope.
The author of the theory of general relativity wrote: "The power of resistance which has enabled the Jewish people to survive for thousands of years has been based to a large extent on traditions of mutual helpfulness. In these years of affliction our readiness to help one another is being put to an especially severe test. May we stand this test as well as did our fathers before us."
