Louis Eilshemius was a painter, poet and composer, who described himself as the "Mightiest Mind Wonder of the Worlds. Supreme Parnassian and Grand Transcendent Eagle of Art." He received the support of numerous artists and collectors including Louise Bourgeois, Gaston Lachaise, Joseph Stella, Alfred Stieglitz, Roy Neuberger, Joseph Hirshhorn, Gertrude Vanderbilt Whitney and others. In 1920, Marcel Duchamp persuaded Katherine Dreier to give the fifty-six year old artist his first solo show at the newly formed Société Anonyme.

Born to a wealthy family in North Arlington, NJ, he attended Cornell University (1882-83), studied at the Art Students League in New York (1884-6) and traveled to Paris to study at the Academie Julien (1886). In 1887 and 1888, his landscapes were accepted by the National Academy of Design for their annual exhibitions.

His works are in numerous public collections including The Metropolitan Museum, NY; Whitney Museum of American Art, NY; Museum of Modern Art, NY; Hirshhorn Museum and Sculpture Garden, Washington, DC; Neuberger Museum, Purchase, NY; Phillips Collection, Washington, DC; Art Institute of Chicago, IL; Corcoran Gallery of Art, Washington, DC; De Young Museum, CA; Los Angeles County Museum of Art, CA; Museum of Fine Arts, Boston, MA and New York Historical Society, NY among others.
