David H. Arrington
David H. Arrington developed a deep interest in photography as a teenager when he began taking pictures and studying the work of Ansel Adams to improve his technique and skills. In his late twenties, Arrington started collecting Adams’ work, a pursuit which over the decades gave rise to one of the largest and most important privately held collections of work by the photographer. Highlights from the collection have been exhibited widely, including in Ansel Adams: Classic Images (Los Angeles County Museum of Art), Ansel Adams at 100 (San Francisco Museum of Modern Art, traveling thereafter to The Art Institute of Chicago, the Hayward Gallery, Berlin’s Kunstbibliothek, Los Angeles County Museum of Art, and The Museum of Modern Art), Georgia O’Keeffe and Ansel Adams, Natural Affinities (The Georgia O’Keeffe Museum), Photography From the Mountains to the Sea (The Royal Museums Greenwich), and Ansel Adams: Eloquent Light, at the Amon Carter Museum of American Art. Born and raised in the Dallas community of Oak Cliff, he currently serves as President of Arrington Oil & Gas Operating LLC in Midland, TX.
Andrea G. Stillman
Andrea G. Stillman worked closely with Ansel Adams as his executive assistant for seven years in the 1970s.

Although she has worked at both the Metropolitan Museum of Art and the Morgan Library in New York, her true calling has always been Ansel Adams and his photographs.
