appear in images made during the 1950s. A year after Bullock died in 1975, Edna took up photography and enjoyed a twenty-year career as an artist before she died in 1997. Barbara formed collaborative relationships with both her parents during their lifetimes and has written extensively on their work. Education Bullock took courses at Columbia University, 1925, and University of West Virginia, mid-1930s; attended and graduated from Art Center School in Los Angeles, 1938-1940. He was a lifelong student of philosophy, physics, general semantics, psychology, theology, spirituality and art. Influences Impressionist and post-Impressionist paintings stimulated Bullock’s initial interest in the visual arts. The photographs of Man Ray and László Moholy-Nagy influenced his early experimental work as did Art Center School professor, Edward Kaminski. Although Bullock enjoyed close associations with Edward Weston, Imogen Cunningham, Ansel Adams, Ruth Bernhard and other prominent west coast photographers, he said, "Theoretical scientists who probe the secrets of the universe and philosophers who seek answers to existence, as well as painters such as Paul Klee who find the thoughts of men of science compatible with art, influence me far more than most photographers." Noteworthy accomplishments Bullock obtained patents in the U.S., Canada, and Great Britain for a "Photographic Process for Producing Line Image" in the late 1940s. He was granted a second U.S. patent on the "Methods and Means for Matching Opposing Densities in Photographic Film" in the early 1950s. In 1957, he was honored with a medal from the Salon of International Photography and, throughout the 1960s, he received several awards from various professional photographic organizations. In 1968, Bullock became a trustee and chairman of the exhibition committee during the formative years of Friends of Photography in Carmel, California. Along with Ansel Adams, Harry Callahan, Aaron Siskind and Frederick Sommer, he became part of the founding group of photographers whose archives established the Center for Creative Photography at the University of Arizona in 1975. Bullock taught advanced photography courses at the Institute of Design in Chicago during Aaron Siskind's sabbatical and at San Francisco State College at the invitation of John Gutmann. He was a guest instructor for the Ansel Adams Yosemite Workshops. Throughout the 1960s and early 1970s, he lectured widely, led photographic workshops, and participated in many seminars and symposia on various topics and issues in photography.
