John William "Uncle Jack" Dey (November 11, 1912 – October 10, 1978) was an American self-taught artist who lived and worked primarily in Virginia. Before he began painting, he worked as a trapper, fisherman, lumberjack, barber, and police officer. Dey was a favorite among the neighborhood children, whose toys and bicycles he fixed, and they affectionately nicknamed him "Uncle Jack".

John Stuart Ingle (1933 – October 30, 2010) was an American contemporary realist artist, known for his meticulously rendered watercolor paintings, typically still lifes. Some criticism has characterized Ingle's work as a kind of magic realism. Ingle was born in Indiana and died, aged 77, in Minnesota.Significant critical recognition of Ingle's work has included the publication of a book, The Eye and the Heart: Watercolors of John Stuart Ingle (Rizzoli International, 1988), authored by Pulitzer Prize–winning journalist John Camp, and including an introduction by Frank H. Goodyear, Jr., president of the Pennsylvania Academy of the Fine Arts (and author of Contemporary Realism since 1960). The 110-page book on Ingle was published in conjunction with major solo exhibitions jointly sponsored by the Wadsworth Atheneum in Hartford, Connecticut, and the Evansville Museum of Arts, History and Science in Evansville, Indiana.

Theodore Scott-Dabo (November 16, 1865 - November 17, 1928) casually known as Scott Dabo, was a French/American tonalist landscape artist thought to be originally from Detroit, Michigan but now known to have been born in Saverne, France. Active both in New York and Paris, he was the younger brother of Leon Dabo. Both artists were Impressionist landscape painters, who shared in a similar manner in style and tone. During the period when they worked together, their subjects were usually landscapes and seascapes in the early morning or evening at twilight, they utilized spare composition and reductive color schemes to evoke what they termed, mood. The Dabo brothers style that had a Whistlerian quality, and like James McNeill Whistler both would come to be labeled Tonalist. The youngest brother in the family, Louis, a writer and publicist, also used the name Scott Dabo.

Frank D. Hagel (born December 20, 1933) is an American realist and impressionist painter and sculptor. His artwork depicts Native Americans, trappers, and wildlife of the western American frontier.

His paintings, known for their authenticity, are found in private as well as corporate art collections across the country and some have been selected for display by the U.S. State Department in American embassies abroad.

George Charles Deem Jr. (August 18, 1932 – August 11, 2008) was an American artist best known for reproducing vivid re-workings of classic images from art history. All artists rework the art of the past, at times imitating, at times extending, and at times rejecting the work of artists they admire. Deem moved the process of homage and change into uncharted territory. Art historian Robert Rosenblum has called Deem's unconventional thematic choices "free-flowing [fantasy] about the facts and fictions of art history."

James McGarrell (February 22, 1930 – February 7, 2020) was an American painter and printmaker known for painting lush figurative interiors and landscapes.

Felix Oscar Schlag (September 4, 1891 – March 9, 1974) was a German born American sculptor who was the designer of the United States five cent coin in use from 1938 to 2004.He was born to Karl and Teresa Schlag in Frankfurt, Germany where as a young man, he served in the German army of World War I. Schlag studied sculpture at the Academy of Fine Arts, Munich. He moved to the United States in 1929.
On April 21, 1938, Schlag's design for the Jefferson nickel was selected by Nellie Tayloe Ross, Director of the United States Mint. Schlag won $1,000 for his winning design of the coin; he had been an award-winning artist in Europe. His prize money was spent on his wife's funeral. In the 1930s, Felix won several sculptural commissions and art prizes including some New Deal commissions to produce work at several post offices, including ones in White Hall, Illinois and schools in Champaign, Illinois and Bloom Township.Schlag accepted the offer of the American government to place his initials, FS, on the nickel beginning in 1966.
The designer relocated to Owosso, Michigan, where he died and is buried. He and his wife Anna, whom he married in 1920, had three children: Feliza (1920), Leo (1921), and Hilda (1929). A memorial was placed by the Michigan State Numismatic Society on September 14, 2008.

Michael Kabotie, also known as Lomawywesa (September 3, 1942 – October 23, 2009) was a Hopi silversmith, painter, sculptor, and poet. He is known for his petroglyph and geometric imagery.

Harold Joe Waldrum (August 23, 1934 – December 13, 2003) was an American artist whose abstract works depict color studies especially of the old adobe churches of Northern New Mexico. He also used a Polaroid SX-70 camera to photograph many of the churches, initially as part of the process in creating his paintings. However, this collection of thousands of photographs became a body of work in and of itself and was exhibited at several galleries and museums.
Before pursuing an artistic career, Waldrum graduated from Western State College and became a public school teacher in Kansas, where he taught music and art for a decade-and-a-half. After receiving a graduate degree from Fort Hays State College in 1970, he became a full-time painter, moving to New Mexico, the focal point of much of his work.
In the later part of his career, Waldrum endeavored to preserve the historic churches that were the inspiration for his paintings. In 1985, he founded an organization to promote this goal and produced a series of documentaries about the deterioration and ultimately demolition of the churches. In the 1980s and 90s, he collaborated with a few printmakers to create a collection of aquatint etchings and linocuts in a style very similar to his paintings.
Waldrum died on December 13, 2003, and he is buried in Columbus, New Mexico, a village near the Mexico–United States border. His works are held in the collections of the Museum of New Mexico, the Palm Springs Art Museum, the Albuquerque Museum, and the Harwood Foundation of Taos, New Mexico.
