The Harvey Wallbanger is reported to have been invented in 1952 by three-time world champion mixologist Donato "Duke" Antone (Paolantonio). Legend has it that the drink was named after a Manhattan Beach surfer who was a regular patron of Duke's "Blackwatch" Bar on Sunset Blvd. in Hollywood during the early 1950s.
