In 1943 this photographer first came to an alpine valley during his military service. There the nineteen-year-old met sculptor Alberto Giacometti -- the beginning of a close friendship that lasted until Giacometti's death in 1966. He remained closely connected to the valley and its people throughout his life, keeping a second home there from 1965. Famous for his portraits of artists, he repeatedly photographed Giacometti there and, later, a Swiss painter friend. Yet his estate also comprises around 5,000 images that take the valley itself as their subject: landscapes, villages, buildings, and people, barely exhibited or noticed until now. This book gathers a representative cross-section of these images, forming a long-term reportage on this unique valley at the southern edge of the country.
