 Rum Swizzles were the drink of choice at what was purportedly the world's first cocktail party held in London, England in 1924 by novelist Alec Waugh.A reference to a (possibly fictitious) "Green Swizzle" drink dates to 1925 (see "Other Swizzles" below).The Rum Swizzle is also mentioned in Sinclair Lewis's 1925 novel "Arrowsmith", which is set in the fictional Caribbean island of St. Hubert.
