Thomas Hart Benton got a grant from the fellow Missourian Harry S. Truman's administration to do many murals, which are still there in the Jefferson City dome building.
He was a expressionist/realist, and regionalist. Had a decades long falling out with young Jason Pollack, a former K.C. Art Institute student of his.
He never fit into the N.Y. scene, leaving in the '30s after painting was on one of the first Time Magazine covers. However, in 2012 the Metropolian museum hosted a "Thomas Hart Benton's America Today Mural Rediscovered" exhib for 3 years.
He was not happy with the left-leaning trend in the NY/Paris school. But as a realist he just represented life. KKK in full regalia for Indiana murals. Just a few years after they had elected Klan governor, so was not popular, to say the least. Was commissioned but no guidelines.
Most of his murals were of working people, unusual for the day, and of historic figures such as Jesse James or Twain's Huck Finn with escaped Slave Jim.
