Jackson Pollock in the context of "Clyfford Still"

Clement Greenberg (/ˈɡriːnbɜːrɡ/) (January 16, 1909 – May 7, 1994), occasionally writing under the pseudonym K. Hardesh, was an American essayist known mainly as an art critic closely associated with American modern art of the mid-20th century and a formalist aesthetician. He is best remembered for his association with the art movement abstract expressionism and the painter Jackson Pollock.

Abstract expressionism in the United States emerged as a distinct art movement in the aftermath of World War II and gained mainstream acceptance in the 1950s, a shift from the American social realism of the 1930s influenced by the Great Depression and Mexican muralists. The term was first applied to American art in 1946 by the art critic Robert Coates. Key figures in the New York School, which was the center of this movement, included such artists as Arshile Gorky, Jackson Pollock, Franz Kline, Mark Rothko, Norman Lewis, Willem de Kooning, Adolph Gottlieb, Clyfford Still, Robert Motherwell, Theodoros Stamos, and Lee Krasner among others.

The movement was not limited to painting but included influential collagists and sculptors, such as David Smith, Louise Nevelson, and others. Abstract expressionism was notably influenced by the spontaneous and subconscious creation methods of Surrealist artists like André Masson and Max Ernst. Artists associated with the movement combined the emotional intensity of German Expressionism with the radical visual vocabularies of European avant-garde schools like Futurism, the Bauhaus, and Synthetic Cubism.

The Sidney and Lois Eskenazi Museum of Art at Indiana University is an art museum at Indiana University Bloomington. It was opened in 1941 as the Indiana University Museum of Art under the direction of Henry Radford Hope.

The present museum building was designed by I.M. Pei and Partners and dedicated in 1982. The museum's collection comprises approximately 45,000 objects, with about 1,400 on display. The collection includes items ranging from ancient jewelry to paintings by Pablo Picasso and Jackson Pollock. In May 2016, after the announcement of the largest cash gift in the museum's history, the museum was renamed the Sidney and Lois Eskenazi Museum of Art in honor of Indianapolis-based philanthropists Sidney and Lois Eskenazi. The museum is located on the Indiana University Bloomington campus at 1133 E. Seventh Street.

Frank Philip Stella (May 12, 1936 – May 4, 2024) was an American painter, sculptor, and printmaker, noted for his work in the areas of minimalism and post-painterly abstraction. He lived and worked in New York City for much of his career before moving his studio to Rock Tavern, New York. Stella's work catalyzed the minimalist movement in the late 1950s. He moved to New York City in the late 1950s, where he created works which emphasized the picture-as-object. These were influenced by the abstract expressionist work of artists like Franz Kline and Jackson Pollock. He developed a reductionist approach to his art, saying he wanted to demonstrate that for him, every painting is "a flat surface with paint on it—nothing more", and disavowed conceptions of art as a means of expressing emotion. He won notice in the New York art world in 1959 when his four black pinstripe paintings were shown at the Museum of Modern Art. Stella was a recipient of the National Medal of Arts in 2009 and the Lifetime Achievement Award in Contemporary Sculpture by the International Sculpture Center in 2011.

Robert Myron Coates (April 6, 1897 – February 8, 1973) was an American novelist, short story writer and art critic. He published five novels; one classic historical work, The Outlaw Years (1930) which deals with the history of the land pirates of the Natchez Trace; a book of memoirs, The View from Here (1960), and two travel books, Beyond the Alps (1962) and South of Rome (1965). During his unusually varied career, Coates explored many different genres and styles of writing and produced three experimental novels, The Eater of Darkness (1926), Yesterday’s Burdens (1933) and The Bitter Season (1946). Highly original, these novels draw upon expressionism, Dadaism and surrealism. His last two novels—Wisteria Cottage (1948) and The Farther Shore (1955)—are examples of crime fiction. Simultaneously to working as a novelist, Coates maintained a life-long career at the New Yorker, whose staff he joined in 1927. The magazine printed more than a hundred of his short stories many of which were collected in three anthologies; All the Year Round (1943), The Hour after Westerly (1957) and The Man Just ahead of You (1964). Also, from 1937 to 1967, Coates was the New Yorker’s art critic and coined the term “abstract expressionism” in 1946 in reference to the works of Hans Hofmann, Arshile Gorky, Jackson Pollock and Willem de Kooning and others. He was elected to the National Institute of Arts and Letters in 1958. Coates was married to sculptor Elsa Kirpal from 1927 to 1946. Their first and only child, Anthony Robertson Coates, was born on March 4, 1934. In 1946, they divorced and Coates married short story writer Astrid Meighan-Peters. He died of cancer of the throat in New York City on February 8, 1973.

Anthony Boucher praised Coates as "one of the most persuasive recorders of the unaccountable and disturbing moment," singling out his fantasy stories for their "haunting tone of uncertainty and dislocation." Floyd C. Gale said that The Eater of Darkness "has been called the first surrealist novel in English".

Arshile Gorky (/ˈɑːrʃiːl ˈɡɔːrki/ AR-sheel GOR-kee; born Vostanik Manoug Adoian, Armenian: Ոստանիկ Մանուկ Ատոյեան; April 15, 1904 – July 21, 1948) was an Armenian-American painter who had a seminal influence on Abstract Expressionism. He spent the last years of his life as a national of the United States. Along with Mark Rothko, Jackson Pollock and Willem de Kooning, Gorky has been hailed as one of the most powerful American painters of the 20th century. The suffering and loss he experienced in the Armenian genocide had crucial influence on Gorky's development as an artist.

Franz Kline (May 23, 1910 – May 13, 1962) was an American painter. He is associated with the Abstract Expressionist movement of the 1940s and 1950s. Kline, along with other action painters like Jackson Pollock, Willem de Kooning, Robert Motherwell, John Ferren, and Lee Krasner, as well as local poets, dancers, and musicians, came to be known as the informal group, the New York School. Although he explored the same innovations to painting as the other artists in this group, Kline's work is distinct in itself and has been revered since the 1950s.

Willem de Kooning (/də ˈkuːnɪŋ/ də KOO-ning, Dutch: [ˈʋɪləm də ˈkoːnɪŋ]; April 24, 1904 – March 19, 1997) was a Dutch-American abstract expressionist artist. Born in Rotterdam, in the Netherlands, he moved to the United States in 1926, becoming a U.S. citizen in 1962. In 1943, he married painter Elaine Fried.

In the years after World War II, De Kooning painted in a style that came to be referred to as abstract expressionism or "action painting", and was part of a group of artists that came to be known as the New York School. Other painters in this group included Jackson Pollock, Elaine de Kooning, Lee Krasner, Franz Kline, Arshile Gorky, Mark Rothko, Hans Hofmann, John Ferren, Nell Blaine, Conrad Marca-Relli, James Brooks, Adolph Gottlieb, Jack Tworkov, Norman Lewis, Anne Ryan, Robert Motherwell, Philip Guston, Clyfford Still, and Richard Pousette-Dart. De Kooning's retrospective held at MoMA in 2011–2012 rendered him one of the best-known artists of the 20th century.
