The Man and His Mind’ features rarely-seen photos of Albert Einstein, his private letters, ground-breaking manuscripts, journals, and equations written in his hand. General readers will be fascinated. Scientists, historians, and scholars will be, too. ‘Einstein. The Man and His Mind‘ is a book that captures the imagination and that anyone can gaze at intently time and time again.Written by a world-class rare book dealer in concert with the owner of what is likely the world’s largest private collection of Einstein photos and memorabilia, the brief annotations and commentary help make historical sense of a life fully lived. The book’s Foreword is by eminent physicist Hanoch Gutfreund, the Einstein Archives academic director at the Hebrew University of Jerusalem.‘Einstein. The Man and His Mind’ belongs in family rooms as well as in public and academic libraries. The book’s astonishing images will prove enthralling for anyone interested in Einstein as an approachable human or as the genius who explored time, space, light, gravity, quantum theory, and cosmology in ways no other scientist had before.
