An excellent illucidation of the people, studios, and material basis which combined to produce some of the earliest examples of cinematic animation. The scope of the book is large, geographically as well as temporally, and that is perhaps its one weakness. As in most good historical books, the author has set the "scene" in which his particular narrative of events is to take place, with some early pages dedicated to the trailblazers of the nascent animation medium such as Emile Reynaud, Winsor McCay, Emile Cohl, and others. However, the focus shifts to the birth and growth of the American studio animation system, and for me, that was where I found the essential heart of the book.
Essentially, I like this book a lot. I think it does follow through on the promise of its title, and is a worthwhile read for anyone interested in media history. But, since animation is still a rather new focus for scholarly work, I find a lot of scholarly writing on the topic suffers slightly from a lack of focus on any particular area (or too much focus on one particular individual to the detriment of others *ahem* Disney...). So yeah, this book is one of the few I've found which talks about early animation pioneers, which is great, but the focus of this book imo is not on them, but on the American studio system which developed out of, or even parallel to, the techniques of these individuals.
