main island of New York City, from Dutch, from a native name, perhaps representing a Delaware (Algonquian) source akin to Munsee munahan "island." Bright favors Munsee /e:nta menahahte:nk/ "where one gathers bows." As the name of a cocktail made of vermouth, whiskey, and a dash of bitters, it is attested by 1878 (in Manhattan cocktail). Related: Manhattanese.
1891, short for Martini cocktail (1886), perhaps from Martini & Rossi, Italian firm that makes vermouth (an ingredient of the drink); the firm was in existence then by that name, but it is not specified among the ingredients in the earliest recipes (such as Harry Johnson's "Bartender's Manual," 1888). Another theory holds that it is a corruption of Martinez, California, the town where the drink was said to have originated. See discussion in Lowell Edmunds' book "Martini, Straight Up" (1998).
As the name of a type of rifle used by the British army from 1871 to 1891, it is attested from 1870, from Friedrich von Martini, who invented the breech mechanism on it.
"woman considered stylish at the turn of the 20th century," 1894, named for U.S. artist and illustrator Charles Dana Gibson (1867-1944), whose main model was his wife, Irene Langhorne (1873-1956). The Gibson cocktail (gin, vermouth, and a pearl onion) is attested by 1914, in some stories ascribed to him but the origin of the term is unknown.
"She looks like a Gibson girl" is not an uncommon saying; and to look like a Gibson girl, is not without its merits. Although our artist has expressed in his drawings disapproval of women usurping the spheres of men, his girls suggest intellectuality. He has none of the doll-like inanely pretty faces which artists used to give women in olden days. His girls look as if they would have opinions of their own and would act with discrimination in the affairs of life. They are tall and graceful and although not in the least like fashion plates, their clothes are becoming and fit perfectly. [National Magazine, May 1898]
