#151 Cocktail: Gibson

    The exact origin of the Gibson is unclear, with numerous popular tales and theories about its genesis. According to one popular theory Charles Dana Gibson is responsible for the creation of the Gibson, when he supposedly challenged Charley Connolly, the bartender of the Players Club in New York City, to improve upon the martini's recipe, so Connolly simply substituted an onion for the olive and named the drink after the patron.
     Gibson could have been the Californian popular onion farmer as seen in the publication Hutchings' illustrated California magazine: Volume 1 (p. 194) by James Mason Hutchings in 1857:
           ONION VALLEY. During the winter of 1852 and '53, snow fell in Onion Yalley to the depth of twenty-five feet, ... Even the towns of Gibson- ville, Seventy-Six, Pine Grove, Whiskey Diggings, and several others, did their trading here.
     There is no direct evidence that Charles Dana, or any other Gibson, created the drink. But, Charles Dana Gibson was certainly the artist who created the 'Gibson girl' illustrations—popular from the 1890s through about the time of the first world war.
