Worse still, the Germans had developed a militaristic state in which eugenics figured prominently, taking ideas that had been developed in America and implementing them in their national policies. Wishing to give credit where credit is due., they acknowledged their debt to the American geneticist Harry Laughlin - Charles Davenport’s amanuensis and drafter of the model sterilization laws in effect in many American states and in the Third Reich - by awarding him an honorary doctorate from Heidelberg University in 1936. But by then Nazi policies were sufficiently scandalous that Laughlin was discouraged from accepting the honor in person and had to pick it up instead at the German Embassy.”

The solution, argued Grant, was to restrict the immigration of Italians and Jews, and to sterilize the feebleminded poor who were already here.

Grant received fan mail for The Passing of the Great Race from political figures as diverse as Theodore Roosevelt and Adolf Hitler. Scientists were no less enthusiastic. The MIT geneticist Frederick Adams Woods lauded the book in the pages of Science, the leading scientific journal in America. A few years later, in the Journal of Heredity, Woods defended the book again, with the argument that the bulk of critical reviews had come from people of southern European ancestry, who would naturally not be disposed to its conclusions.
