As an African American, Angelou experienced firsthand racial prejudices and discrimination in Arkansas. She also suffered at the hands of a family associate around the age of 7: During a visit with her mother, Angelou was raped by her mother’s boyfriend. Then, as vengeance for the sexual assault, Angelou’s uncles killed the boyfriend. So traumatized by the experience, Angelou stopped talking. She returned to Arkansas and spent years as a virtual mute.
Martin Luther King Jr., a close friend of Angelou’s, was assassinated on her birthday (April 4) in 1968. Angelou stopped celebrating her birthday for years afterward, and sent flowers to King’s widow, Coretta Scott King, for more than 30 years, until Coretta’s death in 2006.
One of Angelou’s most famous works is the poem “On the Pulse of Morning,” which she wrote especially for and recited at President Bill Clinton’s inaugural ceremony in January 1993—marking the first inaugural recitation since 1961, when Robert Frost delivered his poem “The Gift Outright” at President John F. Kennedy’s inauguration. Angelou went on to win a Grammy Award (best spoken word album) for the audio version of the poem.
She died recently on May 28, 2014.
