A photographer, painter, filmmaker, and graphic artist, William Klein is one of the most influential and controversial artists of the 20th century. Born in New York, William Klein (1928-2022) grew up in Manhattan. After university studies, he did his military service. Demobilized in Paris, Klein decides to stay there and devote himself to painting, which he studied briefly with Fernand Léger. In 1954, he made a photographic diary of his trip back to New York. Published in 1956, "Life is Good and Good For You in New York" was released in Europe but is deemed too violent for the United States. In the lineage of this success, appears a series of books devoted to other major cities: Rome in 1958, Moscow and Tokyo in 1964, then Paris with a majority of images dating from the years 2000-2002. Klein has exhibited all over the world, notably at the Centre Pompidou (Paris), at the Tate Modern (London), FOAM (Amsterdam) or MoMA (San Francisco). "William Klein – Yes" (French version, January 2023) is the second book published by Atelier EXB, after "Photographisme" in 2017. .
