The person you are referring to is likely Frederick Douglass. When he was a young child, he and his mother were kidnapped, and his mother was sold into slavery. Douglass later escaped from slavery himself and became a prominent abolitionist, orator, and writer, advocating for the rights of African Americans and the end of slavery. His experiences profoundly shaped his views and activism throughout his life.
