ANGELINA EMILY GRIMKE

She and her sister Sarah were outspoken Quakers from Charleston, SC. Their father, a prominent judge, was strongly in favor of slavery and owned hundreds himself. Having observed the cruelty doled out to slaves at close hand, they became committed abolitionists.
Angelina gained notoriety in the early 1830’s when she sent a letter to William Lloyd Garrison, abolitionist and publisher of The Liberator. When it was printed without her permission, she was criticized by the Quakers and given an ultimatum. She refused to recant and was contacted by the abolitionists. Both sisters chose their path and began a life of accomplished distinction.
In the link below she shows what a fine analytical mind she could employ in her argument. Using scripture herself to refute the justification of slavery, she argues against God’s ability to bless any such institution as slavery, and uses Jewish Law to cut down any arguments that were used to justify it. There is no doubt that both sisters had inherited their father’s great legal mind, much to his consternation.
