Calder by Matter contains approximately three hundred images of Alexander Calder’s sculptures, many of which are published here for the rst time. Given unprecedented access to Calder’s work and life during the course of their friendship, acclaimed photographer and graphic designer Herbert Matter captured Calder’s sculptures at different stages of completion, as well as the artist at work in his studio and at home with his family in Roxbury, Connec- ticut. Published in direct collaboration with the Calder Foundation, Calder by Matter offers a new perspective on Calder’s oeuvre, life, and creative process.
