A 1922 letter in which Albert Einstein confided his fears of the rise of anti-Semitism in Germany, more than a decade before the Nazis took power, sold at an Israeli auction on Tuesday for $32,000.

¡°Here are brewing economically and politically dark times, so I¡¯m happy to be able to get away from everything,¡± wrote the 43-year-old physicist to his sister, Maria, after leaving Berlin for a location that goes unmentioned in the letter.

Einstein, who went on to win the Nobel Prize three months later, had departed the German capital after far-rightists assassinated Foreign Minister Walter Rathenu, a friend and fellow Jew, prompting police to warn him that he could be next.

¡°Nobody knows where I am, and I¡¯m believed to be missing,¡± Einstein wrote. ¡°I am doing quite well, in spite of all the anti-Semites among my German colleagues.¡±

The letter refers to a journey Einstein planned to Japan, suggesting that he penned it while waiting to sail out of the northern port of Kiel.

When the Nazis took over Germany in 1933, launching a campaign of anti-Jewish persecution that would culminate in the Holocaust, Einstein was on a lecture tour abroad. He renounced his citizenship and eventually settled in the United States.

¡°What is special in this letter that Einstein really forecast ¡ª he¡¯s seeing in advance, 10 years in advance ¡ª what is going to be in Germany,¡± said Meron Eren, co-founder of the Kedem Auction House in Jerusalem, which sold the artifact to an unidentified bidder.
