One of the most influential photographers of her generation, Annie Leibovitz has produced images as powerful as they are ubiquitous: her work appears regularly on the covers of Vogue and Vanity Fair as well as in campaigns for American Express and Louis Vuitton and in exhibitions around the world. She began her career at Rolling Stone, where, among other notable images, she snapped the last picture of John Lennon before his murder on Dec. 8, 1980. That now famous cover image a naked Lennon enveloped around his wife Yoko Ono is emblematic of the iconic portraiture that has defined Leibovitz's four-decade career.
