In 1935, the City Council of Cleveland, Ohio empowered a special committee to investigate the "identity, motives, aims, and methods" of the "Secret Seven", an anonymous committee of the Cleveland Chamber of Commerce, which, earlier in 1935, distributed a pamphlet concerning the activities of unnamed intellectuals charged with abetting Communists and other subversives in Cleveland. The City Council committee subpoenaed testimony from Munson Havens, executive secretary of the Chamber of Commerce, and from William Frew Long, general manager of the Associated Industries of Cleveland, who lent assistance to the Chamber of Commerce. Long refused to cooperate with the committee and was cited for contempt. Marvin C. Harrison, a Cleveland attorney who offered his counsel to numerous labor-management and intra-union disputes in Cleveland, was counsel for the committee. The activities of the "Secret Seven" were largely discredited, and the council's investigation was soon dropped.
