A lover of literature from an early age, Bender began collecting rare books and helped create the
Book Club of California in 1912. Inspired by his cousin
Anne Bremer, a professional artist, Bender began collecting art, with an emphasis on work by local artists and the arts of China, Japan and Tibet. He became very interested in getting to know and help the artists and writers of the San Francisco Bay Area. Bender enjoyed giving things away even more than he liked acquiring them, and he became a prolific donor to Bay Area museums and libraries. He was once called "the most active buyer—and donor—of the work of California artists the state had ever known." He donated significant collections to what are now the
Fine Arts Museums of San Francisco, the
San Francisco Museum of Modern Art, the
Mills College Art Museum, and the University of California
Berkeley Art Museum and Pacific Film Archive. Beginning in 1932 he donated 260 pieces of Asian art to the
National Museum of Ireland in memory of his mother. He gave collections of rare books and fine printing to
Mills College,
Stanford University, the
University of California and the
San Francisco Public Library. His generosity in Europe earned him the titles of Fellow of the
Royal Society of Antiquaries of Ireland, Fellow of the
Royal Geographical Society, Chevalier of the Legion of Honor of France and Cavaliere of the Crown of Italy. He received honorary degrees from Mills College and the University of California, Berkeley. Stanford University has a Bender Room in its library, and at
Mills College there is a Bender Room in the former
Margaret Carnegie Library. Bender served as a trustee of Mills College, a commissioner of the San Francisco Public Library, and a board member of the California Society of Etchers (today's
California Society of Printmakers),
California Historical Society, Book Club of California, Japan Society, the Home for Aged Disabled, and the
San Francisco Symphony, Art Association, Museum of Art, Opera Association, and Opera Guild. Bender helped launch the career of many artists and photographers, including
Ansel Adams. He financed the publication of Adams's first portfolio (
Parmelian Prints of the High Sierras, 1927) and his first book (
Taos Pueblo, with author
Mary Hunter Austin, 1930). ==Judaism==
