The winter of 1962/1963 turned into one of the harshest in living memory. On February 11, 1963, ill and low on money, Sylvia Plath committed suicide in her kitchen by gas asphyxiation.

Posthumously published collections of her poetry include the celebrated Ariel, published in 1965, and The Collected Poems (1981), which won the Pulitzer Prize for poetry in 1983.
