John was independently wealthy and was an important patron for Biederman from 1931 until 1953, helping to financially support him and encouraging his work. Biederman's farm near Red Wing influenced his work and his ideas about the relationship between art and nature. In the 1950s, he introduced the term Structurism to describe his own work, in order to distinguish it from Constructivism and De Stijl. The New York gallerist Grace Borgenicht visited Biederman in Red Wing in 1979. Borgenicht represented Biederman's work for more than a decade, and he had several solo exhibitions in her New York Gallery between 1980 and 1991. In addition to creating art, Biederman wrote extensively, self-publishing more than a dozen books about art. He also carried on a long correspondence with the physicist David Bohm. The letters exchanged by Biederman and Bohm were published as "The Bohm-Biederman Correspondence: Creativity in Art and Science". Charles Biederman died at home in 2004 at the age of 98. His estate was given to the Weisman Art Museum at the University of Minnesota, which has organized traveling exhibitions of Biederman's work. Biederman's work is in many public collections, including:  Albright-Knox Art Gallery, Buffalo, New York; The Blanton Museum of Art, University of Texas at Austin, Texas; Carnegie Museum of Art, Pittsburgh, Pennsylvania; Chazen Museum of Art, University of Wisconsin, Madison; The Art Institute of Chicago, Illinois; Dallas Museum of Fine Arts, Texas; Detroit Institute of Arts, Michigan; University of East Anglia, Norwich, England; Hirshhorn Museum and Sculpture Garden, Washington, D.C.; The Hunter Museum of American Art, Chattanooga, Tennessee; Lowe Art Museum, University of Miami, Coral Gables, Florida; The Metropolitan Museum of Art, New York; Museum of Fine Arts, Boston; Minneapolis Institute of Art, Minnesota; The Museum of Modern Art, New York; Newark Museum, New Jersey; Philadelphia Museum of Art, Pennsylvania; Tate Modern, London, England; Walker Art Center, Minneapolis, Minnesota; Frederick R.
