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,” and, “Ariel,” as well as “The Bell Jar,” a semi-autobiographical novel published shortly before her death. Plath was clinically depressed for most of her adult life, and was treated multiple times with electro-convulsive therapy, or ECT. On 11 February 1963 she took her own life at the age of 30 by sticking her head in a gas oven.
