Walter Isaacson is the  author of the most comprehensive and well written biography of Albert Esinstein -  Einstein: His Life and Universe and the president of the Aspen Institute.

The Atlantic published  in its last December issue an article of his based on cerrespondence of Einstein around his first visit to the US in 1921, documents which were not available when he wrote the book.

The article seems significant to me not only because of the value of the new documents about one of the most significant personalities in the histry of the 2oth century and his relation to the Zionist cause, but also for revealing aspects about the divisions in the American Jews community concerning the fight for the formation of Israel and support for Zionism that seem to be actual until today.
