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, the artist at work in his studio and at home with his family in Roxbury, Connecticut. Calder by Matter includes original essays by esteemed art critic and Calder biographer Jed Perl, Calder Foundation President and Calder grandson Alexander S. C. Rower (editor of the volume), and Matter student and colleague John T. Hill (designer of the volume). This unique collection of over 300 images, many of which are published here for the first time, offers a new perspective on Calder's oeuvre, life, and creative process. Calder by Matter has been published in direct collaboration with the Calder Foundation.
