 If Chamberlain’s writings served as intellectual fodder for German racial prejudice, Madison Grant (1865–1937) provided similar foundations for American race prejudice against Black people and Native Americans in his popular book The Passing of the Great Race (1916). Rejecting political or educational means of ameliorating the destitution of the subordinate racial groups in America, Grant instead advocated strict segregation and the prohibition of miscegenation, or the interbreeding of members of different races (Hannaford 1996, 358). Like Galton, Grant had similar success in influencing American public policy, both through the imposition of racist restrictions on immigration at the federal level and through the enforcement of anti-miscegenation laws in thirty states, until such prohibitions were finally overturned by the United States Supreme Court in Loving v. Virginia (388 U.S. 1 [1967]).
