A letter written by physicist Albert Einstein to his sister Maria sold at an action in Jerusalem on Tuesday, fetching $32,000 (€28,300).
In the 1922 letter, Einstein described the difficulties facing Jews in Germany as anti-Semitic sentiment was on the rise.
"Here are brewing economically and politically dark times, so I'm happy to be able to get away from everything," wrote the then 43-year-old after leaving Berlin for a location that goes unmentioned in the letter.
At the time, Einstein left the German capital after the assassination of Foreign Minister Walter Rathenau, who was a close friend and also Jewish. Police warned Einstein he could be next.
"What is special in this letter that Einstein really forecast — he's seeing in advance, 10 years in advance — what is going to be in Germany," said Meron Eren, co-founder of the Kedem Auction House in Jerusalem, which sold the letter. The artifact's buyer has not been identified.
'Doing pretty well despite all the anti-Semites'
Einstein is believed to have written the letter while waiting to sail out of the northern German port city of Kiel on a journey to Japan.
"Nobody knows where I am, and I'm believed to be missing," he wrote while in hiding. "I'm doing pretty well, despite all the anti-Semites among the German colleagues," he wrote.
Einstein accepted the Nobel Prize in physics three months after penning the letter. The Nazis took over Germany in 1933 and began a campaign of anti-Jewish persecution that would result in the Holocaust, which killed an estimated 6 million Jews.
Einstein was on a lecture tour abroad when the Nazis seized power, leading him to renounce his citizenship and eventually settle in the United States.
"Don't worry about me, I myself don't worry either, even if it's not quite kosher, people are very upset. In Italy, it seems to be at least as bad," Einstein wrote.
