(1881 - 1974) Rudolph Weisenborn was born in Strassburg, Germany, but was orphaned at the age of nine. He was taken-in by Mid-Western farmer Thomas Westaby and spent his early years in Wisconsin, Iowa and North Dakota. Weisenborn first attended the University of North Dakota in 1898, then the Students School of Art in Denver. Various accounts have him working out west as a gold miner and cowboy.
Around 1912, he settled in Chicago and worked as a window designer for Marshall Fields. Weisenborn is best known as the founder of the Chicago No-Jury Society of Artists. The group was founded because many artists could not get their work accepted into the mainstream Art Institute shows. Weisenborn is quoted as saying that he harbored feelings of disdain for any jury and that his own paintings were frequently rejected by conservative jurors. He was also involved and helped found other radical artists groups such as the Salon des Refuses, Cor Ardens and Neo-Arlimusic. In 1936, he helped found the New York-based American Abstract Artists Group. He created the only abstract mural for the 1933 Century of Progress Exhibition in Chicago and also worked for the Federal Arts Project in the Easel Division. His WPA murals can be found in Crane Technical High School and Nettlehorst Elementary School in Chicago, IL. In 1945, Chicago businessman Herman Spertus commissioned Weisenborn to paint the mural The Fighting Navy for the Great Lakes Naval Training Station. He taught at Hull House (1920), the Chicago Academy of Fine Arts (1922-34), his own Weisenborn Art School (1934-64), and the Austin, Oak Park, River Forest Art League in Oak Park (1941). Weisenborn died in Chicago in 1974.
