"She was there for me always, guiding me through some of the most important years of my life," Winfrey wrote. "The world knows her as a poet but at the heart of her, she was a teacher. ‘When you learn, teach. When you get, give’ is one of my best lessons from her."
Angelou, who is survived by a son, is remembered by her many contributions to the world of literature.
