In 1945 , when Harry S. Truman became President , Morgenthau insisted on accompanying Truman to Potsdam by threatening to quit if he was not allowed to ; Truman accepted his resignation immediately . He devoted the remainder of his life to working with Jewish philanthropies , and also became a financial advisor to Israel . Tal Shahar , an Israeli moshav ( agricultural community ) near Jerusalem , created in 1948 , was named in his honor ( '' Morgenthau '' ( modern spelling '' Morgentau '' ) means " morning dew " in German , and so does " Tal Shahar " in Hebrew )
