This is a wonderful collection. I'd only seen the before and afters of the man with wire-framed glasses before--credited to Dr. Hertog. I believe Belgian hormone doc, Thierry Hertog, MD, is his son or grandson.
What is staggering is to realize how much of what was common medical information in 1914 has been completely lost.
I don't understand why way back when photos were difficult and expensive they have photographic evidence. Now, when photos are digital and free, no doc ever takes our picture.
I want to print up sections of this great find. :D
