In my search for working downloads of Dr. Waldbott's books, I found this tribute from "Fluoride" magazine. (The magazine is available free online.) This tribute gives us an idea of what kind of a man and what kind of a doctor Waldbott was. One of those who wrote a tribute is Sebastopol's John. R. Lee, M.D., who passed away about ten years ago. I had the pleasure of knowing Dr. Lee, who was also a strong opponent of fluoridation. Dr. Lee's articles on fluoridation can easily be found with a google search. Here is the tribute to Dr. Waldbott: https://en.netlog.com/The_HEART_O_Te...blogid=3828921
Dzerach, by using Firefox instead of Internet Explorer, I was able to get the link you provided for "Fluoridation: The Great Dilemma" to work. Also there are still 4 copies of the book on Amazon for less than $1.
To those interested in digging deeper into fluoridation, here is the link to FLUORIDE Journal, the online magazine of the International Society for Fluoride Research (ISFR), which was founded by George Waldbott, M.D. https://www.fluorideresearch.org/
