Historical references

Today Guillaume Thierry, a French physio using and teaching DNM, posted to the Facebook group about his discovery of two old references (see pictures).
It seems he loves to poke through really old books!

The first one:

He tells us:

From 1912! Nineteen TWELVE!!

..... 

But wait! There's more!
The second one: 

This one is from 1872!!!
He says...

So, it seems that others got there before I did.
And that's OK! It's wonderful!
All the people who don't believe something because it hasn't already existed for hundreds of years can rest easy now. There is indeed somewhere else to place trust without cognitively wandering around, forever trapped in the Dark Forest of Mesodoom.
