Would that be Hans Hermes, author of “Enumerability, Decidability, Computability”, “Einführung in die Verbandstheorie”, and others? It only took a few stabs to find that and many other references. Getting hold of the original books and papers (he wrote in German) may be more challenging, but of course he wrote before the internet, and despite Google’s efforts, the day when every old book, journal, and newspaper has been scanned, OCR’d, indexed, and translated into all languages is not yet here. Some things are just not on the net.
Searching for “baryon conservation” yields 2910 results. You can’t have been trying very hard. From a quick glance, baryon number is, so far, found to be conserved. Proton decay would violate it, has been theorised about and looked for, but has not been observed.
Here’s another exercise for those wishing to test their search-fu: what can you find out about the Ion Brezoianu for whom a street in Bucharest is named? And how would you conduct the search? (I had a very boring and trivial reason for wanting to know this once; I found the dates of birth and death of someone I’m guessing to be the same person, but little more.)
what can you find out about the Ion Brezoianu for whom a street in Bucharest is named?
Apparently one of the men whose fame is ultimately based almost exclusively on a street named after them. Ion Brezoianu, 1817-1883, probably a moderately important figure in Romanian national revival. A pedagogue and author of a book called “Manualul mumelor”. I was unable to quickly find what mumelor (or mume, which is the guessed singular nominative indefinite form) means. I am also a bit confused, because the street is called Strada actor Ion Brezoianu, but what I have found doesn’t indicate he was an actor.
As for the method, I have searched for “Ion Brezoianu” -strada -nr -str to eliminate the overwhelming number of links to the street name, and after I have found the years of birth and death, I have included them into the search.

Rubbish.
From:
Like I said, theorised about but not observed.
Has been theorised that the baryon number is conserved. It was observed that it isn’t.
