Book excerpt: The 1950s, 60s, and 70s were defining moments in our nation's history, and San Francisco was at the forefront of the avant-garde artistic, intellectual, and cultural movements of the time. The city gave rise to the most significant countercultural revolutions of the century, including the Beatniks of the 1950s, the hippies in the 1960s, and the gay rights movement in the 1970s. With a selection of fine historic images from her bestselling book Historic Photos of San Francisco in the 50s, 60s, and 70s, Rebecca Schall captures in this companion volume, Remembering San Francisco in the 50s, 60s, and 70s, the revolutionary and tumultuous spirit of these historic times in stunning black-and-white photography.
