It's anyway a must read, Einstein has been the most famous man of his time and a personality that made history until today. The book is comprehensive, both in the initial part which led to his discovery of the theory of relativity and general, on that part of his life more complicated personally (refuge in the United States) and scientifically (contribution then contradict quantum mechanics). But in ways to share the different aspects of the personality of Einstein, the book is not as lively as I expected after reading the bio of S. Jobs.
