HS Chemistry question - when did "stoichiometry" get invented?

I happened to glance at my son's Chem book and no surprise, gee, lots of stuff has changed since I was in school. Still, I was curious as to how the entire realm of measurement seems to have gotten a fancy name, and I was wondering when it changed. Is there a Mr. Stoichio? What happened?

Just curious.

I don't think it is that it didn't exist when you were in HS. More than likely is that the amount of content covered has gone up (not sure when you were in HS). My parents would always comment how the things we covered in HS were more advanced than the things they covered in HS.

That, or your son is a lot smarter than you :)

Yes, I saw that - I did start out on google - but it only confuses things. If Richter did invent stoichiometry in 1795, why wasn't it in my HS honors chem book in the 1970's? What happened? And then why between 1970 and today has it come to prominence? When? Who?

In my further research online I came across this video. It's not about stoichiometry but I found it educational. I'm sure it's a repost but I didn't find it in search.

I went thought university Chemistry in the 60's, and the concepts of stoichiometry were fundamentals taught clearly then and earlier in High School. The early realization that materials always reacted with each other in fixed proportions (by weight) was a vital clue to developing the concepts of molecular and atomic masses, and of Equivalent Weights of reagents. Ultimately they contributed partially to the development of the Periodic Table of the Elements, although that is based on Atomic Numbers (and hence valence shell electron structures), not Atomic Weights. This was all developed well before the 20th Century, and I recall it's being taught as a fundamental part of the science "back when".
