As a disclaimer, this is the only biography I have read of Einstein, so I have nothing to compare it to. That said, there is one pro and many cons to this book. From a positive perspective, It is unquestionable that the author did his research for this book. There is such a large volume of facts, conversations, observations, and general statements about einstein's life that the reader is left knowing that the author did his research. However, that is where the notable aspects of this book end. The largest short coming here was the writing style. This was not written in a way to be enjoyed. It is a factual tome, written very clearly to simply include everything the author knows. At times, it was painfully clear that the author was forcing random facts into passages, just to have that information included. There are no transitions between topics, no literary devices to help make this an enjoyable story. This is a lengthy statement of facts about Einstein, put into sequential order. Having not read any other Einstein biography, I cannot recommend another book to read instead if this one. Indeed, this book was very good about providing a personal, in depth view of Einstein. Nevertheless, it was not well written. If you do decide to move forward with this book, be assured that you will come away with a superior knowledge of a great man. You will not find a biography that is an enjoyable read, however, which is something I am firmly believe nonfiction should still try to achieve.
