John Ashbery was born in Rochester, New York, in 1927. His books of poetry include Breezeway; Quick Question; Planisphere; Notes from the Air: Selected Later Poems, which was awarded the 2008 International Griffin Poetry Prize; A Worldly Country; Where Shall I Wander; and Self-Portrait in a Convex Mirror, which received the Pulitzer Prize for Poetry, the National Book Critics Circle Award, and the National Book Award. The winner of many prizes and awards both nationally and internationally, in 2011 he received the Medal for Distinguished Contribution to American Letters from the National Book Foundation, and in 2012 he received a National Humanities Medal, presented by President Obama at the White House. He lived in New York until his death, aged ninety, in 2017.Kenneth Koch is grouped with John Ashbery, Frank O'Hara and James Schuyler, a grouping which tends to underplay the real differences between each poet's projects; their collaborations were inventive because of their differences, not their similarities, and what marks all four is the ability to work at tangents without ever quite abandoning the circumference. Koch started writing when he was five, under the influence of Shelley, whom he outgrew in his teens, taking doses of Byron and eventually of Eliot. As a soldier in the Philippines, he kept himself sane by playing in language, making lines to make life's unbearables absurd. He studied at Harvard with Delmore Schwartz, and Ashbery and O'Hara were classmates. His prose memoirs, plays and poems have an abundance and a formal variety unparalleled in American writing. His Selected Poems and One Train are published in the United Kingdom by Carcanet. Frank O’Hara was born in Baltimore, Maryland, in 1926, and grew up in Grafton, Massachusetts. He served in the US navy (1944-46) in the South Pacific, and attended the universities of Harvard and Michigan. In 1951 O’Hara settled in Manhattan, and soon became a central figure in a number of the city’s artistic circles. For most of the fifteen years that he lived in New York he worked at the Museum of Modern Art, graduating from the front desk to become Associate Curator. He was a passionate advocate of Abstract Expressionist painters such as Willem de Kooning, Jackson Pollock, and Franz Kline. O’Hara wrote an enormous quantity of poetry, little of which was published during his lifetime, but which was much admired by friends such as John Ashbery, Kenneth Koch, V.R. 'Bunny' Lang, James Schuyler, Fairfield Porter and Larry Rivers. He died on 25 July 1966, from injuries sustained in a beach-buggy accident on Fire Island. He is buried at Green River Cemetery, East Hampton, Long Island. His Collected Poems (edited by Donald Allen) was published in 1971, and won the National Book Award for Poetry. James Schuyler was born in Chicago on 9 November 1923. He attended Bethany College of West Virginia from 1941 to 1943. In the late 40s he moved to New York City where he worked for NBC and befriended W. H. Auden. He later moved to Italy, where he lived in Auden's rented apartment and worked as his secretary. He attended the University of Florence between 1947 and 1948. He returned to the United States afterwards, and settled in New York City, where he lived with John Ashbery and Frank O'Hara. On 12 April 1991, he died following a stroke. Mark Ford was born in 1962.
