Sylvia Plath was an American poet, novelist, and short story writer. She is credited with advancing the genre of confessional poetry and is best known for two of her published collections, The Colossus and Other Poems (1960) and Ariel (1965), as well as The Bell Jar, a semi-autobiographical novel published shortly before her suicide in 1963. The Collected Poems was published in 1981, which included previously unpublished works. For this collection Plath was awarded a Pulitzer Prize in Poetry in 1982, making her the fourth to receive this honour posthumously.
