Glück was recognised for "her unmistakable poetic voice, that with austere beauty makes individual existence universal" said the Swedish Academy, which oversees the award.
She is the first American to win the prestigious award since Bob Dylan was honored in 2016. Toni Morrison was the last American to recieve the prize before him, winning 1993.
Louise has received numerous honors for her work. In addition to most of the major awards for poetry in the United States, she has received multiple fellowships from the National Edowment For the Arts and the Guggenheim Foundation.
Glück was born in New York in 1943 and is a professor of English at Yale University in Connecticut. She made her debut in 1968 with "Firstborn," and won the Pulitzer Prize in 1993 and the National Book Award in 2014.
