This may have been true, but Black doesn't have the evidence to back up his claim. Moreover, he doesn't need to pile on the hyperbole when he's dug up so many compelling examples of the love affair between American eugenicists and German race scientists: for example, that Corporal Hitler read his favorite American eugenicists while in jail in 1924 and later sent a fan letter to Madison Grant, author of The Passing of the Great Race; or the strange case of Edwin Katzen-Ellenbogen, a Jewish psychiatrist, eugenicist and naturalized American citizen, who was found guilty by the Nuremberg tribunal for committing war crimes in Buchenwald.

By 1937 the book had sold 16,000 copies in the United States alone. Nordic theory was also strongly embraced by the racial hygiene movement in Germany in the early 1920s and 1930s; however, they typically used the term "Aryan" instead of "Nordic", though the principal Nazi ideologist, Alfred Rosenberg, preferred "Aryo-Nordic" or "Nordic-Atlantean". Stephen Jay Gould described The Passing of the Great Race as "The most influential tract of American scientific racism." Grant's work was embraced by proponents of the National Socialist movement in Germany; Passing was the first non-German book ordered to be reprinted by the Nazis when they took power, and Adolf Hitler wrote to Grant that, "The book is my Bible".
