Frances Ellen Watkins Harper (1825–1911)
At a time in America when the majority of Black people were enslaved and women were rarely encouraged to have political opinions—much less share them in public—Frances Ellen Watkins Harper became a genuine celebrity as an orator. Second only to abolitionist Frederick Douglass in terms of prominent African American writers of her era, the poet, essayist and novelist frequently went on speaking tours to discuss slavery, civil rights and suffrage—and donated many of the proceeds from her books to the Underground Railroad.
When it came to the cause of women’s suffrage, Harper was convinced it would not be achieved unless Black and white women worked together. But while Harper initially worked with leaders like Stanton and Anthony, “she was also one of the first women to call them out in terms of their racism,” notes Jenkins. Harper’s most famous confrontation came when she spoke at the 1866 National Women's Rights Convention. “You white women speak here of rights,” Harper told the crowd, calling them out for their lack of female solidarity across racial divides. “I speak of wrongs.”
