  Significantly, Cooper’s Voice is published before Booker T. Washington’s famous “Atlanta Address” (1895), his autobiographical works The Story of My Life and Work (1896) and Up From Slavery (1901), as well as Washington’s historic two-volume The Story of the Negro (1909). It is also published ahead of W.E.B. Du Bois’s well-known “The Conservation of Races” (1897) speech, the publication of The Souls of Black Folk (composed of essays and speeches written by Du Bois between 1897 and 1903), and Darkwater: Voices from Within the Veil (1920) which not only borrows the language of Cooper’s book title, but also relies on Cooper’s astute insights on race and gender. As Mary Helen Washington and Joy James have noted, Du Bois quoted a passage from Cooper’s “Womanhood: A Vital Element in the Regeneration and Progress of a Race,” in his essay “The Damnation of Women” from Darkwater, however; he truncates Cooper’s full argument in his selective quotations and he fails to acknowledge her as the source of the quote.
