Hildegarde Haas was born in Frankfort, Germany in 1926. Her education included summer classes at the Colorado Springs Fine Art Center followed by two years at the University of Chicago. Receiving a scholarship to the Art Students League, she studied under Vaclav Vytlacil and Morris Kantor. She was completely self-taught as a printmaker and explored the woodcut medium with other students at the ASL and "learned as she went." After relocating to Northern California in 1951, Haas became affiliated with Bay Area art organizations, including the San Francisco and Oakland Art Associations and the Arts and Crafts Coop in Berkeley. Haas continued to exhibit in national and local painting and print exhibitions and she had solo exhibitions at the Dallas Museum of Fine Arts and the Kaiser Aluminum Corporation. Her work is represented in the permanent collections of Museum of Modern Art, Library of Congress, City of San Francisco, Seattle Museum of Fine Art, Dallas Museum of Fine Art, Worcester Art Museum and the Cleveland Art Museum.
