Louise Emerson Ronnebeck was an American painter now best known for her work as a muralist. She submitted entries to 16 competitions for the Section of Painting and Sculpture, winning and completing two commissions. Although her body of work included a significant number of both commissioned frescoes as well as easel paintings, few are known to have survived.

Arnold Rönnebeck was a German-born American modernist artist and museum administrator. He was a vital member of both the European and American avant-garde movements of the early twentieth century before settling in Denver, Colorado. Rönnebeck was a sculptor and painter, but is best known for his lithographs that featured a range of subjects including New York cityscapes, New Mexico and Colorado landscapes and Native American dances.
