Ansel (Feb. 20 1902 — Apr. 22, 1984), photographer and environmentalist, was born in San Francisco, California, the son of Charles Hitchcock Adams, a businessman, and Olive Bray. His black-and-white landscape photographs of the American West, especially Yosemite National Park, have been widely reproduced on calendars, posters, and in books.His black-and-white images were not “realistic” documents of nature. Instead, they sought an intensification and purification of the psychological experience of natural beauty. He created a sense of the sublime magnificence of nature that infused the viewer with the emotional equivalent of wilderness, often more powerful than the actual thing.
