Probably the first that was ever mentioned as a "cocktail" and gave its name to the corresponding glass. The name "Old Fashioned" was given to a bourbon whiskey cocktail in 1880 at the "Pendennis Club", a club for men only in Louisiana. The recipe was created by a bartender, but became widely known by a bourbon distiller, Colonel James E. Pepper, who brought it to the Wardorf-Astoria Hotel.
