Arnold Gelb.
Arnold Gelb was one of the leaders of Howard Washburne's League for Brotherhood and the head of Universities for Justice. Gelb called for an end to all forms of government in the Confederation of North America. Gelb does not have an entry in Sobel's index.
Sobel's source for Arnold Gelb's tenure with the League for Brotherhood is Farley Shaw's Voices of the Great Protest (New York, 1930).
