It's hard to pinpoint who specifically invented the sea breeze cocktail. It dates back to the 1920s, towards the end of the prohibition era. However, it started as a mixed drink consisting of gin and grenadine and has morphed through the years into what it is today. One of its earliest acknowledgments of a Sea Breeze cocktail is found to be in Harry Craddock's 1930 Savoy cocktail book, who was a legendary bartender.
