She directed the National Americanization Committee (NAC), the most important private organization promoting Americanization during World War I. Speaking for the NAC in 1916, proposed to combine efficiency and patriotism in her Americanization programs. It would be more efficient, she argued, once the factory workers could all understand English and therefore better understand orders and avoid accidents. Once Americanized, they would grasp American industrial ideals and be open to American influences and not subject only to strike agitators or foreign propagandists. The result, she argued would transform indifferent and ignorant residents into understanding voters, to make their homes into American homes, and to establish American standards of living throughout the ethnic communities. Ultimately, she argued it would "unite foreign-born and native alike in enthusiastic loyalty to our national ideals of liberty and justice."John F.
