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.
