CATHERINE BEECHER

By 1837, more and more women were being published, in order to influence public thought. They did not have the freedom to speak in public, so this was their best alternative. Catherine, the older sister of Harriet Beecher Stowe, like her brothers and sister was passionate concerning the abolition of slavery. She wrote... a now famous essay addressed to Angelina Emily Grimke, herself a well-known advocate of abolition, along with her sister Sarah.
