Despite his family's social stature, Morgenthau was frozen out of bicker (excluded from Eating club membership) as a sophomore in 1937, along with four of the other 11 Jewish students in the class.

Morgenthau III was producer of Prospects of Mankind with Eleanor Roosevelt (1959),[14] The Negro and the American Promise (1963),[citation needed] and Conversation[15] with Svetlana Alliluyeva (daughter of Stalin) (1967).

[17] Waiting in line at city hall in the predawn, he looked at the damp ground and decided to call himself Morgen Tau ("morning dew'' in German).

[18][19] His and Brunhilda Morgenthau's son, Lazarus[20] (1815–1897) was making nicotine-free cigars, candy from pine needles, tongue scrapers, and gum-label machines.

[21] As Wilson's ambassador to the Ottoman Empire (Turkey) during the crucial years before and during World War I, he supported the Jews in Palestine and heroically rescued Armenians persecuted by the Turks.

Henry Jr. (1891–1967)[22] was a close friend of both Eleanor and Franklin Roosevelt,[23] FDR's Secretary of the Treasury and leader of U.S. efforts on behalf of Holocaust survivors.

[24] In his book Henry Morgenthau III casts doubt on the alleged Communist associations of his father's Treasury aide Harry Dexter White, whom Whitaker Chambers accused of being a Soviet spy and conspirator.
