Henri Cartier‐Bresson Reinterprets his Career

Between 1952 and 1974, Henri Cartier‐Bresson significantly revised his understanding of himself as a photojournalist. This article analyses that change through close readings of his book, The Decisive Moment (1952), an interview in Le Monde (1974), and other published statements and unpublished letters by Cartier‐Bresson. It draws on interviews and correspondence with his widow Martine Franck, with his friend and representative Helen Wright, and with associates at Magnum Photos. It argues that what appears from a superficial reading of the interview to be a rejection of photography and photojournalism was in fact Cartier‐Bresson's first public expression of a long‐simmering opposition to the consumer society – which he as an ecologist strongly opposed – and to fashion and advertising photography, which he believed promoted unnecessary consumption. It concludes that Cartier‐Bresson reinterpreted his past by seeing himself as a surrealist to the denial of having done photojournalism. The article is predicated on the belief that understanding the change in Cartier‐Bresson's own conception of his work is essential to a full understanding of it.

The Ecological Facades of Patrick Blanc

The urban geographer Matthew Gandy explores the work of French botanist Patrick Blanc, who applies his scientific knowledge and preoccupations to urban design. After his invention of the mur végetal (green wall), a botanical and structural system for greening buildings, in 1988, Blanc's work has gone on to transcend the creation of merely living walls. Through his landscape schemes Blanc has recognised the city's rich potential for verdant metamorphosis, transforming fern- and moss-covered streets and buildings into unlikely ravines or rainforests.
