American poet whose willingness to confront the horrible, the difficult, and the painful has resulted in a body of work characterized by insight and a severe lyricism.

After attending Sarah Lawrence College in Bronxville, New York, and Columbia University in New York City, Glück taught poetry at numerous colleges and universities, including Harvard and Yale. Her first collection of poetry, Firstborn (1968), uses a variety of first-person personae, all disaffected or angry. The collection's tone disturbed many critics, but Glück's exquisitely controlled language and imaginative use of rhyme and metre delighted others. Although its outlook is equally grim, The House on Marshland (1975) shows a greater mastery of voice. There, as in her later volumes, Glück's personae include historic and mythic figures such as Gretel and Joan of Arc (Joan of Arc, Saint). Her adoption of different perspectives became increasingly imaginative; for example, in The Sick Child, from the collection Descending Figure (1980), her voice is that of a mother in a museum painting looking out at the bright gallery. The poems in The Triumph of Achilles (1985), which won the National Book Critics Circle Award for poetry, address archetypal subjects of classic myth, fairy tales, and the Bible. These concerns are also evident in Ararat (1990), which has been acclaimed for searing honesty in its examination of the family and the self.

In 1993 Glück won a Pulitzer Prize for The Wild Iris (1992). Her later works include Meadowlands (1996), The First Five Books of Poems (1997), and The Seven Ages (2001). Averno (2006) was her well-received treatment of the Persephone myth. She was also editor of The Best American Poetry 1993 (1993). Her essay collection Proofs and Theories: Essays on Poetry was published in 1994. In 2001 she was awarded the Bollingen Prize for Poetry. Glück also served as poet laureate consultant in poetry to the Library of Congress (2003–04).
