Paul Jackson Pollock (January 28, 1912 – August 11, 1956), known professionally as Jackson Pollock, was an American painter and a major figure in the abstract expressionist movement. He was well known for his unique style of drip painting.
During his lifetime, Pollock enjoyed considerable fame and notoriety; he was a major artist of his generation. Regarded as reclusive, he had a volatile personality, and struggled with alcoholism for most of his life. In 1945, he married the artist Lee Krasner, who became an important influence on his career and on his legacy.
Pollock died at the age of 44 in an alcohol-related single-car accident when he was driving. 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.
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 Echo Park, California, he enrolled at Los Angeles' 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.
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.
From 1938 to 1942, during the Great Depression, Pollock worked for the WPA Federal Art Project.
Trying to deal with his established alcoholism, from 1938 through 1941 Pollock underwent Jungian psychotherapy with Dr. Joseph 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.Recently, 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 Mural (1943), which measures roughly 8 feet tall by 20 feet long, 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."
The two artists met while they both exhibited at the McMillen Gallery in 1942. Krasner was unfamiliar but yet intrigued with Pollock's work and went to his apartment, unannounced, to meet him following the gallery.  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. 
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.
He started using synthetic resin-based paints called alkyd enamels, which, at that time, was a novel medium. Pollock described this use of household paints, instead of artist’s paints, as "a natural growth out of a need". He used hardened brushes, sticks, and even basting syringes as paint applicators. Pollock's technique of pouring and dripping paint is thought to be one of the origins of the term action painting. With this technique, Pollock was able to achieve a more immediate means of creating art, the paint now literally flowing from his chosen tool onto the canvas. By defying the convention of painting on an upright surface, he added a new dimension by being able to view and apply paint to his canvases from all directions.
A possible 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. With Jackson Pollock, the critic Clement Greenberg saw Sobel's work there in 1946. 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".
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.
Pollock observed American Indian sandpainting demonstrations in the 1940s. Referring to his style of painting on the floor, Pollock stated, “I feel nearer, more a part of the painting, since this way I can walk round it, work from the four sides and literally be in the painting. This is akin to the methods of the Indian sand painters of the West.” Other influences on his drip technique include the Mexican muralists and Surrealist automatism. Pollock denied reliance on "the accident"; he usually had an idea of how he wanted a particular piece to appear. His technique combined the movement of his body, over which he had control, the viscous flow of paint, the force of gravity, and the absorption of paint into the canvas. It was a mixture of controllable and uncontrollable factors. Flinging, dripping, pouring, and spattering, he would move energetically around the canvas, almost as if in a dance, and would not stop until he saw what he wanted to see. As another important influence can be cited Wolfgang Paalen's article on Totem Art of the indigenous people of British Columbia and his Fumage paintings which he had seen at Julien Levy's exhibition of Paalen's surrealist paintings in 1940. Pollock owned a signed and dedicated copy of the Amerindian Number of Paalen's magazine (DYN 4-5, 1943), in which the revolutionary space concept in totemist art from the North-West-Coast is broadly discussed from an artist's point of view. Another strong impact must have been Paalen's fumage technique, as it was the surrealist technique with the most magic appeal for those painters who looked for new ways of making appear what was called the unseen or the possible. Fumage was presented also in Matta's workshop about which Steven Naifeh reports: »Once, when Matta was demonstrating the Surrealist technique [Paalen's] Fumage, Jackson [Pollock] turned to Busa and said in a stage whisper: ›I can do that without the smoke.‹« Pollock's painter friend Fritz Bultman even stated (hinting at the revolutionary possibility-space of Paalen): "It was Wolfgang Paalen, who started it all."
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.
Namuth said that when he entered the studio:
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. Subsequently, over 10 scientific groups have performed fractal analysis on over 50 of Pollock's works. In 2005, fractal analysis was used for the first time in an authenticity dispute stirring controversy. A recent study which used fractal analysis as one of its techniques achieved a 93% success rate distinguishing real from fake Pollocks. Current research of Fractal Expressionism focuses on human response to viewing fractals. Cognitive neuroscientists have shown that Pollock’s fractals induce the same stress-reduction in observers as computer-generated fractals and Nature's fractals.
Pollock's most famous paintings were made during the "drip period" between 1947 and 1950. He rocketed to fame following an August 8, 1949 four-page spread in Life magazine that asked, "Is he the greatest living painter in the United States?" At the peak of his fame, Pollock abruptly abandoned the drip style.
Pollock's work after 1951 was darker in color, including a collection painted in black on unprimed canvases. These paintings have been referred to as his 'Black pourings' and when he exhibited them at the Betty Parsons Gallery in New York none of them sold. Parsons later sold one to a friend at half the price. The departure from his earlier style wasn't what his collectors wanted. Although these works show Pollock attempting to find a balance between abstraction and depictions of the figure.
He later returned to using color and continued with figurative elements. During this period, Pollock had moved to a more commercial gallery; the demand for his work from collectors was great. In response to this pressure, along with personal frustration, his alcoholism deepened.
Continuing to evade the viewer's search for figurative elements in his paintings, Pollock abandoned titles and started numbering his works. He said about this: "...look passively and try to receive what the painting has to offer and not bring a subject matter or preconceived idea of what they are to be looking for." Pollock's wife, Lee Krasner, said Pollock "used to give his pictures conventional titles... but now he simply numbers them. Numbers are neutral. They make people look at a picture for what it is—pure painting."
Lee Krasner's influence on her husband's art was something critics began to reassess by the later half of the 1960's due to the rise of feminism at the time.Krasner's extensive knowledge and training in modern art and techniques helped her bring Pollock up to date with what contemporary art should be. Krasner was often considered to learn her husband in the dominant tenants of modernistic painting. Pollock was then able to change his style to fit a more organized and cosmopolitan genre of modern art, Krasner became the one judge he could trust. At the beginning of the two artists' marriage, Pollock would entrust his counterpart's opinions on what worked and what did not in his pieces. Lee Krasner was also responsible for introducing him to many collectors, critics, and artists, including Herbert Matters, who would help further his career as an emerging artist.  John Bernard Myers, a noted art dealer, was once quoted to say that "there would never have been a Jackson Pollock without a Lee Pollock", whereas Fritz Bultman, a fellow painter, had referred to Pollock as Krasner's "creation, her Frankenstein", both men recognizing the immense impact Krasner had on Pollock's career.
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 due to Pollock's continuing struggle with 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.
For the rest of her life, his widow Lee Krasner managed his estate and ensured that Pollock's reputation remained strong despite changing art world trends. The couple are buried in Green River Cemetery in Springs with a large boulder marking his grave and a smaller one marking hers.
The Pollock-Krasner House and Studio is owned and administered by the Stony Brook Foundation, a nonprofit affiliate of Stony Brook University. Regular tours of the house and studio occur from May through October.
A separate organization, the Pollock-Krasner Foundation, was established in 1985. The foundation functions as the official estate for both Pollock and his widow Lee Krasner, 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.
Lee Krasner donated Pollock's papers in 1983 to the Archives of American Art. They were later archived with Lee Krasner's papers. The Archives of American Art also houses the Charles Pollock papers, which include correspondence, photographs, and other files relating to his brother Jackson Pollock.
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 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 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 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 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.
Untitled 1950, which the New York-based Knoedler Gallery had sold in 2007 for $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 281 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 1960, Ornette Coleman's album Free Jazz: A Collective Improvisation featured a Pollock painting as its cover artwork.
The British indie band The Stone Roses were heavily influenced by Pollock; they have cover artwork made of pastiches of his work.
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.
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 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 $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.
Pollock is mentioned many times throughout the play Red, by John Logan. The play's main character, Mark Rothko, was a fellow abstract expressionist of his era. In the play, Rothko speaks to his assistant, Ken, about Pollock's works and his death.
A Pollock painting is shown throughout the 2016 movie The Accountant, by Bill Dubuque. The movie's main character, played by Ben Affleck, gains the painting through his career. He subsequently gifts it to the character played by Anna Kendrick at the end of the film.
Pollock's work has been the subject of important critical debates. The critic Robert Coates once derided a number of Pollock’s works as “mere unorganized explosions of random energy, and therefore meaningless.” 
Jean Helion the French abstract painter on the other hand, on first seeing a 'Pollock' remarked 'it filled out space going on and on because it did not have a start or end to it'.
In a famous 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.
Clement Greenberg supported Pollock's work on formalistic grounds. It fit well with Greenberg's view of art history as a progressive purification in form and elimination of historical content. He considered Pollock's work to be the best painting of its day and the culmination of the Western tradition via Cubism and Cézanne to Manet.
Reynold's News in a 1959 headline said, "This is not art—it's a joke in bad taste."
The Congress for Cultural Freedom, an organization to promote American culture and values, backed by the CIA, sponsored exhibitions of Pollock's work. Certain left-wing scholars, most prominently Eva Cockcroft, have argued that the U.S. government and wealthy elite embraced Pollock and abstract expressionism to place the United States in the forefront of global art and devalue socialist realism. Cockcroft wrote that Pollock became a "weapon of the Cold War".
Pollock, himself described his art as 'motion made visible memories arrested in space'.
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.
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 $140,000,000. 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 $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 $20.5 million—$23 million with fees—within its estimated range of $20 million to $30 million.
In 2013, Pollock's Number 19 (1948) was sold by Christie's for a reported $58,363,750 during an auction that ultimately reached $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 $200 million, from David Geffen.
Jackson Pollock's influence on his wife's, Lee Krasner's, artwork is often discussed by art historians. Many people thought that Krasner began to reproduce and reinterpret her husband's chaotic paint splatters in her own work. There are several accounts where Krasner intended to use her own intuition, as a way to move towards Pollock's "I am nature" technique as a way to reproduce nature in her art. Lee Krasner's largest challenge as an artist was to establish a separation between herself and her husband that was not strictly the otherness of a woman. Pollock's staining into raw canvas was adapted by the Color Field painters Helen Frankenthaler and Morris Louis. Frank Stella made "all-over composition" a hallmark of his works of the 1960s. The Happenings artist Allan Kaprow, sculptors Richard Serra and Eva Hesse, and many contemporary artists have retained Pollock’s emphasis on the process of creation; they were influenced by his approach to process, rather than the look of his work. In 2004, One: Number 31 was ranked the eighth-most influential piece of modern art in a poll of 500 artists, curators, critics, and dealers.
