Answer: Elizabeth Cady Stanton did most of the writing and Susan B. Anthony managed the business affairs of the women's rights movement.
They both travelled throughout the US giving speeches.
Mrs. Stanton was a master of words and could write and speak to perfection of the things Susan B. Anthony saw and felt but could not herself express.
However, Susan B. Anthony was known for her anti-slavery work, especially the underground railroad, she had a vision of a racially integrated society.
Because of the "spectrum" for which Susan B. Anthony rallied, I would choose her for your answer.
