Gibson

is a variation of the classic dry Martini, created at San Francisco’s Bohemian Club in 1898 and named for either illustrator Charles Dana Gibson, creator of the Gibson Girl drawings, or socialite Walder D. K. Gibson, both members. See Martini. Originally, it was simply a Dry Martini without orange bitters, but once that drink lost the bitters, its distinguishing mark became its garnish: a pickled onion. See onion.
