Irving Penn (June 16, 1917 – October 7, 2009) was an American photographer known for his portraiture and fashion photography. Penn worked for many years doing fashion photography for Vogue magazine, founding his own studio in 1953. He was among the first photographers to pose subjects against a simple grey or white backdrop and used this simplicity more effectively than other photographers. Expanding his austere studio surroundings, Penn constructed a set of upright angled backdrops, to form a stark, acute corner. Subjects photographed with this technique included Martha Graham, Marcel Duchamp, Pablo Picasso, Georgia O'Keeffe, W. H. Auden, and Igor Stravinsky.
