Claims To 'Inventing The First Cocktail':
1. It was invented by Betsy Flanaghan in 1776, during the American Revolution and was a mix of rum, rye and apple juice. Betsy served this drink to Washington's officers and it was called a cocktail because she dressed it with a rooster's feather.
2. An apothecary called Antoine Amedee Peychaud, invented mixed drinks in New Orleans around 1795. These drinks were made in an egg-cup or coqquetier in French.
English speakers eventually changed this to cocktay and then cocktail. The first known printed use of the word cocktail was in 1803; Farmer's Cabinet (Amherst, New Hampshire, April 28), "drank a glass of cocktail - excellent for the head."
