When I was a kid I would ask my dad stuff like who invented pizza, and my dad would say Mr. Pizza. or who invented cups and my dad would say Mr. Cup, who invented shoes, Mr. Shoe, etc. So the Negroni came about as a boozier version of he Americano. The story goes that Mr. Negroni walked in to a bar in Florence, Italy and asked the bartender to serve his favorite drink, the Americano, but with gin instead of soda water. And lo’ and behold, the Negroni was born. So Yes in this case, the Negroni, was invented by Mr. Negroni.
