[9] Kaufman traveled to the Sahara Desert and wrote: "you look at the horizon all day long and feel that you are staring at eternity."

[13] In 1939, under the auspices of the "American Federation of Peace", an unknown entity of which he was the president and probably only member,[14] Kaufman produced several publications.

[3] Although Kaufman's book had a minimal impact in the United States, it gained attention in Nazi Germany, where propagandists used it as evidence of an international Jewish plan to destroy the German people.

On July 24, 1941, the Nazi Party's newspaper, Völkischer Beobachter, published a front-page article on the book titled: "The Product of Criminal Jewish Sadism: Roosevelt Demands the Sterilization of the German People."

The newspaper alleged that Kaufman was a close ally of Samuel Irving Rosenman, an advisor to Franklin Delano Roosevelt and that: "Given the close relationship of the writer to the White House, this monstrous war program can be seen as a synthesis of genuine Talmudic hatred and Roosevelt's views on foreign policy.

[15] Nazi Propaganda Minister Joseph Goebbels read the book in early August and immediately grasped its value, writing in his diary: "This Jew did a real service for the enemy [German] side.

Portions of the book were read on national radio, and Goebbels ordered the printing of five million copies of a pamphlet that summarized Kaufman's ideas.

[14] When the Jews of Hanover were forced from their homes on September 8, 1941, German authorities cited Kaufman's book as one of the reasons.

They employed every possible German cruelty against the Jews long before my book was published.The Nazi propaganda ministry continued to publish pamphlets, posters and flyers on Kaufman's ideas through the end of the war, and also urged newspapers and public speakers to remind Germans of Kaufman's book.

Kaufman's last major appearance in Nazi propaganda occurred in late 1944, when a five-page section on him was included in the widely published booklet Never!, which described a number of alleged plots to destroy Germany.

[14] Randall Bytwerk, an historian of communications at Calvin College, concluded that "[a] German at the time could not have missed encountering" propaganda about Kaufman.

Berel Lang, a visiting professor of philosophy and letters at Wesleyan University, failed to locate Kaufman in the records of the city of Newark and in other sources.

[21] From 1949 through 1981, the Kaufmans sold "Charcrust Broil-It" barbecue seasoning powder from their home in East Orange, NJ.
