Query: A Noble subject for sure

Very interesting that 2 books would be published in one year on this rather obscure history. I've yet to read the Richard Korman bio published earlier, but plan to. I was not at all familiar with any of this amazing story of rubber, and I'm glad I spent the time to find out. Reading this story of Charles Goodyear left me hungering for more. Certainly, the author has the facts and has done the full research, and it seems mostly to be on the page, but I think in the hands of a greater power, the subject and its huge meaning to our world today could have been better amplified. The book seems more geared to the academic mind set, and could come off a bit on the dry side. At this point, I don't know of a better book on the subject, and since it is well-researched, if you want to learn about the story of rubber, this is a good starting point!
