In the six-volume “History of Women’s Suffrage,” betrays more than a hint of vanity when it credits the Stanton-Anthony cohort with starting a movement that actually had diverse origins and many mothers. Its worst offenses may be that it rendered nearly invisible the black women who labored in the suffragist vineyard and that it looked away from the racism that tightened its grip on the fight for the women’s vote in the years after the Civil War.
