Ganus Jr. and James D. Bales were also heavily involved. NEP materials were used nationwide by groups such as the U.S. armed forces, public schools, colleges and universities, chapters of the American Legion, and local chambers of commerce. Some uses became controversial: Some companies required their employees to attend NEP-sponsored seminars and enclosed copies of Benson's lectures with their paychecks in hopes of addressing perceived restlessness. The Fulbright Memorandum of June 1961 raised concerns about use of NEP materials in the military. The NEP was charged with being a "Radical Right" organization in the 1964 book Danger on the Right, which Bales responded to in his 1965 book Americanism under Fire. The close relationship between Harding and the NEP delayed the college's accreditation until 1954 when the school incorporated it as a separate entity, although Benson, Ganus, and Bales continued their involvement and the NEP board was nearly identical to the college's. In the 1970s, the program dwindled in notoriety and moved to Oklahoma Christian College. The American Studies Institute continues as a legacy of this program. Race relations Segregation During segregation in the United States, the school remained racially segregated for most of the tenure of president George S. Benson, who defended Harding's delay in integrating. Benson believed Black people were inferior because they fell under the Curse of Ham. In 1957, student body president Bill Floyd circulated a "statement of attitude" that Harding was ready to integrate, and it was signed by over 75% of the students, faculty, and staff of the college. In response Benson made an address entitled titled “Harding College and the Colored Problem”, in which he put down the idea of integration as youthful idealism, and insisted that students should defer to the judgment of older people with more experience, such as the Harding board of trustees. He went further, stating that Black people were far better off in the US than in other countries, and that integration would result in destruction of property, the spread of venereal diseases, and increased pregnancies. He also stated that mixed marriages would lead to broken homes and a rise in crime. Benson maintained that mixing of the races was against the divine order. In 1953, Norman Adamson became the first black person accepted to Harding. However, when administrators learned he was black he was denied admission. In 1963, three black students were admitted to the Searcy campus,
