A one-of-a-kind, hard-cover, 4.4 pound book with rarely-seen photos of Albert Einstein as well as of beautifully preserved letters, manuscripts, journals, and even equations written in Einstein's hand. Extraordinary among Einstein biographies, the book presents the holdings of an unparalleled private collection of Einstein memorabilia and helps place in historical context his ideas about time, gravity, quantum theory, and cosmology. With annotations and commentary by the collection owner, by a world-class rare book dealer, and by eminent physicist Hanoch GuIreund of the Hebrew University of Jerusalem, this book is fascinating reading for people interested in scientist biographies. It's also an exquisite photo research opportunity for scholars of the history and philosophy of physics.
