"This book is a fascinating, entertaining look at world history in the first half of the 20th century. Told from a humorous, objective point of view, all history textbooks should be so compelling.One of this book's strength is that it gives rise to important figures that general history overlooks. I was completely unfamiliar with insurance magnate/composer Charles Ives or physicist Richard Feynman, for example, before reading this book. Estrin paints interesting portraits of both, which I have to assume have basis, though they remain as intriguing as the fictitious characters.The more familiar figures like FDR and Oppenheimer receive warm treatment as well. They come in and out of the observant narrative as quirky as the rest of the characters.A hidden treasure of this book is that it includes Estrin's bibliography. I intend to mine some of those books to learn more about the characters Estrin has introduced so delightfully."
