Let’s review about Aluminum
I found him studying this 1937 text I’d given him. It was retrieved from the dump, and had all kinds of cool historical stuff in it–like how Napoleon funded (and bankrupted himself) trying to accelerate the refining of the hyperpricey aluminum fabrication process. In his day, only royalty could afford aluminum, so they got to have cool aluminum cutlery while their friends just made do with gold and silverware!
Also learned that the discovery (as with so many things) was happening in Oberlin, Ohio and in France by separate young chemists.
After this photo, we pitched the book in the thrift shop pile.
