Maya Angelou’s 1969 memoir, 'I Know Why the Caged Bird Sings,' was a revolutionary work that brought the autobiography into the realm of high art. It was the first non-fiction bestseller by an African American woman. The book explores themes of identity, trauma, and the power of literature to heal. Angelou had spent five years of her childhood as a 'mute' following a traumatic event, finding her voice again through the poetry of Shakespeare and Langston Hughes. She famously read her poem 'On the Pulse of Morning' at Bill Clinton's 1993 inauguration, becoming the first poet to do so since Robert Frost. Her work remains a cornerstone of American literature, celebrated for its lyrical beauty and unwavering honesty.
