Lisette Model, and Dorothea Lange. During this time White created his first grouping of photos and text in a non-narrative form, a sequence he called Amputations. Although it was scheduled to be shown at the California Palace of the Legion of Honor, the exhibition was canceled because White refused to allow the photographs to be shown without text, which included some wording that expressed his ambiguity about America's post-war patriotism. The next three years were some of White's most prolific in terms of creative output. In addition to taking dozens of land- and waterscapes, he made dozens of photographs that evolved into some of his most compelling sequences. Three in particular showed his continuing struggles with his sexuality. Song Without Words, The Temptation of St. Anthony Is Mirrors, and Fifth Sequence/Portrait of a Young Man as Actor all depict "the emotional turmoil he feels over his love and desire for men." In 1949 White purchased a small Zeiss Ikonta camera and began a series of urban street photographs. Over the next four years he took nearly 6,000 images, all inspired by his newfound interest in the poetry of Walt Whitman. The project, which he called City of Surf, included photographs of San Francisco's Chinatown, the docks, people on the streets and various parades and fairs around town. The period of 1951–52 is one of the formative times in White's career. He participated in a Conference on Photography at the Aspen Institute, where the idea of creating a new journal of photography was discussed by Ansel Adams, Dorothea Lange, Beaumont and Nancy Newhall, Frederick Sommer and others. Soon after Aperture magazine was founded by many of these same individuals. White volunteered for and was approved as editor, and the first issue appeared in April 1952. Aperture quickly became one of the most influential magazines about photography, and White remained as editor until 1975. Near the end of 1952 White's father, from whom he had been estranged for many years, died in Long Beach, California. In 1953 Walter Chappell introduced White to the I Ching, an ancient Chinese book of philosophy and divination, and White continued to be influenced by and refer to this text throughout the rest of his life. He was especially intrigued by the concepts of yin and yang, in which apparently opposite or contrary forces may be conceived as complementary. Later that same year a reorganization at CSFS
