Maya Angelou's iconic first memoir, I Know Why the Caged Bird Sings, was published in spring 1969. The book was an instant best-seller, and was one of the first literary accounts of growing up as a black girl in the southern states of America, including graphic depictions of rape and racism. Louise Hidalgo talks to Maya Angelou's friend and biographer, former magazine editor, Marcia Gillespie, about the book and how it helped to establish Maya Angelou as one of the great voices of her generation.
