Much—too much—of 1940s American culture stayed stuck in the racist 1920s, although some code words fell out of fashion. The roots of “Nordic” in Madison Grant’s Nazi-like eugenics disabled it for use in the 1940s. Prewar names of the categories of dolichocephalic and brachycephalic also disappeared, though FBI “wanted” posters and mug shots continued to depict miscreants in profile as well as full-face. The shape of the head, it seems, still said a good deal. Nor did the cephalic index fade as in the American’s ideal face shape—the dolichocephalic, long-headed oval of Norman Rockwell’s quintessential Americans, rather than the brachycephalic square or round. Be tall, be blue-eyed, and, if a woman, be blond.
