While the drink’s origins are unknown, the most widely reported account is Count Camillo Negroni invented it in 1919 in Florence, Italy, at Caffè Casoni, now called Caffè Cavalli. Count Negroni asked the bartender, Fosco Scarselli, to strengthen his favorite cocktail, the Americano, by adding gin rather than the normal soda water. The bartender also added an orange garnish instead of the typical lemon garnish to signify it was a different drink.
