• Painter Thomas Hart Benton, 1889

Benton was born in Neosho, Missouri, into an influential family of politicians. He had a sister Mildred. Benton's father, Colonel Maecenas Benton, was a lawyer and four times elected as U.S. congressman. Known as the "little giant of the Ozarks", Maecenas named his son after his uncle Thomas Hart Benton, one of the first two United States Senators elected from Missouri. Given his father's political career, Benton spent his childhood shuttling between Washington D.C. and Missouri. His father sent him to Western Military Academy in 1905-06, hoping to shape him for a political career. Growing up in two different cultures, Benton rebelled against his father's plans. He wanted to develop his interest in art, which his mother supported. As a teenager, he worked as a cartoonist for the Joplin American newspaper, in Joplin, Missouri.

With his mother's encouragement, in 1907 Benton enrolled at the Art Institute of Chicago. Two years later, he moved to Paris in 1909 to continue his art education at the Académie Julian. His mother supported him financially and emotionally to work at art until he married in his early 30s. His sister Mildred said, "My mother was a great power in his growing up." In Paris, Benton met other North American artists, such as the Mexican Diego Rivera and Stanton Macdonald - Wright, an advocate of Synchromism. Influenced by the latter, Benton subsequently adopted a Synchromist style.

After studying in Europe, Benton moved to New York City in 1913 and resumed painting. During World War I, he served in the U.S. Navy and was stationed at Norfolk, Virginia. His war related work had an enduring effect on his style. He was directed to make drawings and illustrations of shipyard work and life, and this requirement for realistic documentation strongly affected his later style. Later in the war, classified as a "camoufleur," Benton drew the camouflaged ships that entered Norfolk harbor. His work was required for several reasons: to ensure that U.S. ship painters were correctly applying the camouflage schemes, to aid in identifying U.S. ships that might later be lost, and to have records of the ship camouflage of other Allied navies. Benton later said that his work for the Navy "was the most important thing, so far, I had ever done for myself as an artist."

At age 33 Benton married Rita Piacenza, an Italian immigrant, in 1922. They met while Benton was teaching art classes for a neighborhood organization in New York City, where she was one of his students. The couple had a son, Thomas Piacenza Benton, born in 1926, and a daughter, Jessie Benton, born in 1939. They were married for 53 years until Thomas's death in 1975. Rita died ten weeks after her husband.

On his return to New York in the early 1920s, Benton declared himself an "enemy of modernism"; he began the naturalistic and representational work today known as Regionalism. Benton was active in leftist politics. He expanded the scale of his Regionalist works, culminating in his America Today murals at the New School for Social Research in 1930 - 31. In 1984 the murals were purchased and restored by AXA Equitable; they now hang in the lobby of the AXA Equitable Tower at 1290 Sixth Avenue in New York City. In December 2012 AXA donated the murals to the Metropolitan Museum of Art. They will go on display in 2015. They show how Benton absorbed and used the influence of the Spanish artist El Greco.

Benton broke through to the mainstream in 1932. A relative unknown, he won a commission to paint the murals of Indiana life planned by the state in the 1933 Century of Progress Exhibition in Chicago, Illinois. The Indiana Murals stirred controversy; Benton painted everyday people, and included a portrayal of events in the state's history which some people did not want publicized. Critics attacked his work for showing Ku Klux Klan (KKK) members in full regalia. The KKK reached its peak membership in 1925. In Indiana, 30% of adult males were estimated to be members of the Klan, and in 1924 KKK members were elected as governor, and to other political offices.

These mural panels are now displayed at Indiana University in Bloomington, with the majority hung in the "Hall of Murals" at the Auditorium. Four additional panels are displayed in the former University Theatre (now the Indiana Cinema) connected to the Auditorium. Two panels, including the one with images of the KKK, are located in a lecture classroom at Woodburn Hall.

In 1932, Benton also painted The Arts of Life in America, a set of large murals for an early site of the Whitney Museum of American Art. Major panels include Arts of the City, Arts of the West, Arts of the South and Indian Arts. In 1953 five of the panels were purchased by the New Britain Museum of American Art in Connecticut, and have since been displayed there.

On December 24, 1934, Benton was featured on one of the earliest color covers of Time magazine. Benton's work was featured along with that of fellow Midwesterners Grant Wood and John Steuart Curry in an article entitled "The U.S. Scene". The trio were featured as the new heroes of American art, and Regionalism was described as a significant art movement.

In 1935, after he had "alienated both the left - leaning community of artists with his disregard for politics and the larger New York - Paris art world with what was considered his folksy style", Benton left the artistic debates of New York for Missouri. He was commissioned to create a mural for the Missouri State Capitol in Jefferson City. A Social History of Missouri is perhaps Benton’s greatest work. As with his earlier work, controversy arose over his portrayal of the state's history, as he included the subjects of slavery, the Missouri outlaw Jesse James, and the political boss Tom Pendergast. With his return to Missouri, Benton embraced the Regionalist art movement.

He settled in Kansas City, Missouri and accepted a teaching job at the Kansas City Art Institute. This base afforded Benton greater access to rural America, which was changing rapidly. Benton's sympathy was with the working class and the small farmer, unable to gain material advantage despite the Industrial Revolution. His works often show the melancholy, desperation and beauty of small-town life. In the late 1930s, he created some of his best known work, including the allegorical nude Persephone. It was considered scandalous by the Kansas City Art Institute, and was bought by the showman Billy Rose, who hung it in his New York nightclub, the Diamond Horseshoe. It is now held by the Nelson - Atkins Museum of Art in Kansas City. Karal Ann Marling, an art historian, says it is "one of the great works of American pornography."

In 1937, Benton published his autobiography, An Artist in America, which was critically acclaimed. The writer Sinclair Lewis said of it: “Here’s a rare thing, a painter who can write.” During this period, Benton also began to produce signed, limited edition lithographs, which were sold at $5.00 each through the Associated American Artists Galleries based in New York.

Benton's autobiography indicates that his children were enrolled in City and Country School in exchange for his teaching art there. He included Caroline Pratt in "City Activities with Dance Hall," one of the ten panels in "America Today."

Benton taught at the Art Students League of New York from 1926 to 1935 and at the Kansas City Art Institute from 1935 to 1941. His most famous student, Jackson Pollock, whom he mentored in the Art Students League, founded the Abstract Expressionist movement. Pollock often said that Benton's traditional teachings gave him something to rebel against.

Benton's students in New York and Kansas City included many painters who contributed significantly to American art. They included Pollock’s brother Charles Pollock, Charles Banks Wilson, Frederic James, Lamar Dodd, Reginald Marsh, Charles Green Shaw, Margot Peet, Jackson Lee Nesbitt, Roger Medearis, Glenn Gant, Fuller Potter and Delmer J. Yoakum. Benton also briefly taught Dennis Hopper at the Kansas City Art Institute; Hopper was later known for being an independent actor, filmmaker and photographer.

In 1941 Benton was dismissed from the Art Institute after he said the typical art museum was "a graveyard run by a pretty boy with delicate wrists and a swing in his gait." He made additional disparaging references to what he said was the excessive influence of homosexuals (which he called "the third sex") in the art world.

During World War II, Benton created a series titled The Year of Peril, which portrayed the threat to American ideals by fascism and Nazism. The prints were widely distributed. Following the war, Regionalism fell from favor, eclipsed by the rise of Abstract Expressionism. Benton remained active for another 30 years, but his work included less contemporary social commentary and portrayed pre-industrial farmlands.

He continued to paint murals, including Lincoln (1953), for Lincoln University in Jefferson City, Missouri; Trading At Westport Landing (1956), for The River Club in Kansas City; Father Hennepin at Niagara Falls (1961) for the Power Authority of the State of New York; Turn of the Century, Joplin (1972) in Joplin; and Independence and the Opening of The West, for the Harry S. Truman Library in Independence. His commission for the Truman Library mural led to his developing a friendship with the former U.S. President that lasted for the rest of their lives.

Benton died in 1975 at work in his studio, as he completed his final mural, The Sources of Country Music, for the Country Music Hall of Fame in Nashville, Tennessee.

In 1977, Benton's 2-1/2 story late Victorian residence and carriage house studio in Kansas City was designated by Missouri as the Thomas Hart Benton Home and Studio State Historic Site. The historic site been preserved nearly unchanged from the time of his death; clothing, furniture and paint brushes are still in place. Displaying 13 original works of his art, the house museum is open for guided tours.
