Ranks among his country's most distinguished twentieth century photographers. Portraits of artists made his name internationally, and his images of a celebrated sculptor at his Paris studio or in his native alpine valley continue to shape the public image of that artist today. Marking his centenary, this book offers a fresh look at his multi-faceted body of work, based on an extensive reappraisal of his estate, featuring a concise selection of iconic and lesser-known images, including hitherto little-published early work that prompts a reassessment of his entire oeuvre.
