Calder by Matter offers an intimate and wholly unique window into the life and work of Alexander Calder, as seen through the lens of his friend and acclaimed photographer Herbert Matter. Given unprecedented access to Calder s work and life during the course of their friendship, 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, and Matter student and colleague John T. Hill. 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.
