Paul Jackson Pollock was born in Cody, Wyoming, in 1912, the youngest of five sons. His parents, Stella May (née McClure) and LeRoy Pollock, were born and grew up in Tingley, Iowa, and were educated at Tingley High School. Pollock’s mother is interred at Tingley Cemetery, Ringgold County, Iowa. His father had been born with the surname McCoy, but took the surname of his adoptive parents, neighbors who adopted him after his own parents had died within a year of each other. Stella and LeRoy Pollock were Presbyterian; they were of Irish and Scots-Irish descent, respectively. LeRoy Pollock was a farmer and later a land surveyor for the government, moving for different jobs. Stella, proud of her family’s heritage as weavers, made and sold dresses as a teenager. In November 1912, Stella took her sons to San Diego; Jackson was just 10 months old and would never return to Cody. He subsequently grew up in Arizona and Chico, California.

While living in the Vermont Square neighborhood of Los Angeles, he enrolled at Manual Arts High School, from which he was expelled. He had already been expelled in 1928 from another high school. During his early life, Pollock explored Native American culture while on surveying trips with his father. He was also heavily influenced by Mexican muralists, particularly José Clemente Orozco, whose fresco Prometheus he would later call “the greatest painting in North America”.

In 1930, following his older brother Charles Pollock, he moved to New York City, where they both studied under Thomas Hart Benton at the Art Students League. Benton’s rural American subject matter had little influence on Pollock’s work, but his rhythmic use of paint and his fierce independence were more lasting. In the early 1930s, Pollock spent a summer touring the Western United States together with Glen Rounds, a fellow art student, and Benton, their teacher.

Pollock was introduced to the use of liquid paint in 1936 at an experimental workshop in New York City by the Mexican muralist David Alfaro Siqueiros. He later used paint pouring as one of several techniques on canvases of the early 1940s, such as Male and Female and Composition with Pouring I. After his move to Springs, he began painting with his canvases laid out on the studio floor and he developed what was later called his “drip” technique.

From 1938 to 1942 Pollock worked for the WPA Federal Art Project. During this time Pollock was trying to deal with his established alcoholism; from 1938 through 1941 he underwent Jungian psychotherapy with Dr. Joseph L. Henderson and later with Dr. Violet Staub de Laszlo in 1941–42. Henderson engaged him through his art, encouraging Pollock to make drawings. Jungian concepts and archetypes were expressed in his paintings. Some historians have hypothesized that Pollock might have had bipolar disorder. Pollock signed a gallery contract with Peggy Guggenheim in July 1943. He received the commission to create the 8-by-20-foot (2.4 by 6.1 m) Mural (1943) for the entry to her new townhouse. At the suggestion of her friend and advisor Marcel Duchamp, Pollock painted the work on canvas, rather than the wall, so that it would be portable. After seeing the big mural, the art critic Clement Greenberg wrote: “I took one look at it and I thought, ‘Now that’s great art,’ and I knew Jackson was the greatest painter this country had produced.” The catalog introducing his first exhibition described Pollock’s talent as “volcanic. It has fire. It is unpredictable. It is undisciplined. It spills out of itself in a mineral prodigality, not yet crystallized.”

Austrian artist Wolfgang Paalen’s article on totem art of the indigenous people of British Columbia, in which the concept of space in totemist art is considered from an artist’s point of view, influenced Pollock as well; Pollock owned a signed and dedicated copy of the Amerindian Number of Paalen’s magazine (DYN 4–5, 1943). He had also seen Paalen’s surrealist paintings in an exhibition of in 1940. Another strong influence must have been Paalen’s surrealist fumage technique, which appealed to painters looking for new ways to depict what was called the unseen or the possible. The technique was once demonstrated in Matta’s workshop, about which Steven Naifeh reports, “Once, when Matta was demonstrating the Surrealist technique [Paalen’s] Fumage, Jackson [Pollock] turned to (Peter) Busa and said in a stage whisper: ‘I can do that without the smoke.'” Pollock’s painter friend Fritz Bultman even stated, “It was Wolfgang Paalen who started it all.”

The two artists met while they both exhibited at the McMillen Gallery in 1942. Krasner was unfamiliar, yet intrigued with Pollock’s work and went to his apartment, unannounced, to meet him following the gallery exhibition. In October 1945, Pollock and Lee Krasner were married in a church with two witnesses present for the event. In November, they moved out of the city to the Springs area of East Hampton on the south shore of Long Island. With the help of a down-payment loan from Peggy Guggenheim, they bought a wood-frame house and barn at 830 Springs Fireplace Road. Pollock converted the barn into a studio. In that space, he perfected his big “drip” technique of working with paint, with which he would become permanently identified. When the couple found themselves free from work they enjoyed spending their time together cooking and baking, working on the house and garden, and entertaining friends.

One definitive influence on Pollock was the work of the Ukrainian American artist Janet Sobel (1894–1968) (born Jennie Lechovsky). Peggy Guggenheim included Sobel’s work in her The Art of This Century Gallery in 1945. Jackson Pollock and art critic Clement Greenberg saw Sobel’s work there in 1946 and later Greenberg noted that Sobel was “a direct influence on Jackson Pollock’s drip painting technique.” In his essay “American-Type Painting,” Greenberg noted those works were the first of all-over painting he had seen, and said, “Pollock admitted that these pictures had made an impression on him”.

In 1950, Hans Namuth, a young photographer, wanted to take pictures (both stills and moving) of Pollock at work. Pollock promised to start a new painting especially for the photographic session, but when Namuth arrived, Pollock apologized and told him the painting was finished.

Untitled 1950, which the New York-based Knoedler Gallery had sold in 2007 for US$17 million to Pierre Lagrange, a London hedge-fund multimillionaire, was subject to an authenticity suit before the United States District Court for the Southern District of New York. Done in the painter’s classic drip-and-splash style and signed “J. Pollock”, the modest-sized painting (15 by 28 1/2 in) was found to contain yellow paint pigments not commercially available until about 1970. The suit was settled in a confidential agreement in 2012.

In a 1952 article in ARTnews, Harold Rosenberg coined the term “action painting” and wrote that “what was to go on the canvas was not a picture but an event. The big moment came when it was decided to paint ‘just to paint.’ The gesture on the canvas was a gesture of liberation from value—political, aesthetic, moral.” Many people assumed that he had modeled his “action painter” paradigm on Pollock.

In 1955, Pollock painted Scent and Search, his last two paintings. He did not paint at all in 1956, but was making sculptures at Tony Smith’s home: constructions of wire, gauze, and plaster. Shaped by sand-casting, they have heavily textured surfaces similar to what Pollock often created in his paintings.

Pollock and Krasner’s relationship began to crumble by 1956, owing to Pollock’s continuing alcoholism and infidelity involving Ruth Kligman. On August 11, 1956, at 10:15 pm, Pollock died in a single-car crash in his Oldsmobile convertible while driving under the influence of alcohol. At the time Krasner was visiting friends in Europe and she abruptly returned on hearing the news from a friend. One of the passengers, Edith Metzger, was also killed in the accident, which occurred less than a mile from Pollock’s home. The other passenger, Ruth Kligman, an artist and Pollock’s mistress, survived. In December 1956, four months after his death, Pollock was given a memorial retrospective exhibition at the Museum of Modern Art (MoMA) in New York City. A larger, more comprehensive exhibition of his work was held there in 1967. In 1998 and 1999, his work was honored with large-scale retrospective exhibitions at MoMA and at The Tate in London.

While painting this way, Pollock moved away from figurative representation, and challenged the Western tradition of using easel and brush. He used the force of his whole body to paint, which was expressed on the large canvases. In 1956, Time magazine dubbed Pollock “Jack the Dripper” due to his painting style.

Reynold’s News, in a 1959 headline, said, “This is not art—it’s a joke in bad taste.”

In 1960, Ornette Coleman’s album Free Jazz: A Collective Improvisation featured a Pollock painting, The White Light, as its cover artwork.

In 1973, Number 11, 1952 (also known as Blue Poles) was purchased by the Australian Whitlam government for the National Gallery of Australia for US$2 million (A$1.3 million at the time of payment). At the time, this was the highest price ever paid for a modern painting. The painting is now one of the most popular exhibits in the gallery. It was a centerpiece of the Museum of Modern Art’s 1998 retrospective in New York, the first time the painting had been shown in America since its purchase.

Lee Krasner donated Pollock’s papers in 1983 to the Archives of American Art. They were later archived with her own papers. The Archives of American Art also houses the Charles Pollock papers, which include correspondence, photographs, and other files relating to his brother Jackson.

In the early 1990s, three groups of movie makers were developing Pollock biographical projects, each based on a different source. The project that at first seemed most advanced was a joint venture between Barbra Streisand’s Barwood Films and Robert De Niro’s TriBeCa Productions (De Niro’s parents were friends of Krasner and Pollock). The script, by Christopher Cleveland, was to be based on Jeffrey Potter’s 1985 oral biography, To a Violent Grave, a collection of reminiscences by Pollock’s friends. Streisand was to play the role of Lee Krasner, and De Niro was to portray Pollock. A second was to be based on Love Affair (1974), a memoir by Ruth Kligman, who was Pollock’s lover in the six months before his death. This was to be directed by Harold Becker, with Al Pacino playing Pollock.

A separate organization, the Pollock-Krasner Foundation, was established in 1985. The foundation functions as the official estate for both Pollock and his widow, but also under the terms of Krasner’s will, serves “to assist individual working artists of merit with financial need”. The U.S. copyright representative for the Pollock-Krasner Foundation is the Artists Rights Society.

John Squire, guitarist in British indie band The Stone Roses, created the band’s album and single covers, and was heavily influenced by Pollock; his cover artwork was often a conscious replication of Pollock’s style, starting in 1989 with the album The Stone Roses.

The Pollock-Krasner Authentication Board was created by the Pollock-Krasner Foundation in 1990 to evaluate newly found works for an upcoming supplement to the 1978 catalogue. In the past, however, the Pollock-Krasner Foundation has declined to be involved in authentication cases.

In 1999, physicist-artist Richard Taylor used computer analysis to show similarities between Pollock’s painted patterns and fractals (patterns that recur on multiple size scales) found in natural scenery, reflecting Pollock’s own words “I am Nature”. His research team labelled Pollock’s style Fractal Expressionism.

In 2000, the biographical film Pollock, based on the Pulitzer Prize-winning biography, Jackson Pollock: An American Saga, directed by and starring Ed Harris, was released. Marcia Gay Harden won the Academy Award for Best Supporting Actress for her portrayal of Lee Krasner. The movie was the project of Ed Harris, who portrayed Pollock. He was nominated for the Academy Award for Best Actor. Harris himself painted the works seen in the film. The Pollock-Krasner Foundation did not authorize or collaborate with any production.

In 2003, 24 Pollockesque paintings and drawings were found in a locker in Wainscott, New York. In 2005, The Pollock-Krasner Foundation requested a fractal analysis to be used for the first time in an authenticity dispute stirring controversy by researchers at the University of Oregon, which identified differences between the patterns in the 6 disputed paintings analyzed and those in 14 established Pollocks. Pigment analysis of the paintings by researchers at Harvard University showed the presence in one painting of a synthetic pigment that was not patented until the 1980s, and materials in two others that were not available in Pollock’s lifetime.

In 2004, One: Number 31, 1950 was ranked the eighth-most influential piece of modern art in a poll of 500 artists, curators, critics, and dealers.

In November 2006, Pollock’s No. 5, 1948 became the world’s most expensive painting, when it was sold privately to an undisclosed buyer for the sum of US$140 million. Another artist record was established in 2004, when No. 12 (1949), a medium-sized drip painting that had been shown in the United States Pavilion at the 1950 Venice Biennale, fetched US$11.7 million at Christie’s, New York. In 2012, Number 28, 1951, one of the artist’s combinations of drip and brushwork in shades of silvery gray with red, yellow, and shots of blue and white, also sold at Christie’s, New York, for US$20.5 million— US$23 million with fees—within its estimated range of US$20 million to US$30 million.

In 2006, a documentary, Who the *$&% Is Jackson Pollock? was made concerning Teri Horton, a truck driver who in 1992 bought an abstract painting for five dollars at a thrift store in California. This work may be a lost Pollock painting, but its authenticity is debated.

In 2007, a traveling museum exhibition of the paintings was mounted and was accompanied by a comprehensive book, Pollock Matters, written by Ellen G. Landau, one of the four sitting scholars from the former Pollock Krasner Foundation authentication panel from the 1990s, and Claude Cernuschi, a scholar in Abstract Expressionism. In the book, Ellen Landau demonstrates the many connections between the family who owns the paintings and Jackson Pollock during his lifetime to place the paintings in what she believes to be their proper historic context. Landau also presents the forensic findings of Harvard University and presents possible explanations for the forensic inconsistencies that were found in three of the 24 paintings. However, the scientist who invented one of the modern pigments dismissed the possibility that Pollock used this paint as being “unlikely to the point of fantasy.”

In September 2009, the art historian Henry Adams claimed in Smithsonian magazine that Pollock had written his name in his famous painting Mural (1943). The painting is now insured for US$140 million. In 2011, the Republican Iowa State Representative Scott Raecker introduced a bill to force the sale of the artwork, held by the University of Iowa, to fund scholarships, but his bill created such controversy that it was quickly withdrawn.

In 2013, Pollock’s Number 19 (1948) was sold by Christie’s for a reported US$58,363,750 during an auction that ultimately reached US$495 million total sales in one night which Christie’s reports as a record to date as the most expensive auction of contemporary art.

In February 2016, Bloomberg News reported that Kenneth C. Griffin had purchased Jackson Pollock’s 1948 painting Number 17A for US$200 million, from David Geffen.
