Thomas Nast was a German-born American caricaturist and editorial cartoonist often considered to be the "Father of the American Cartoon". He was a critic of Democratic Representative "Boss" Tweed and the Tammany Hall Democratic party political machine. Among his notable works were the creation of the modern version of Santa Claus and the political symbol of the elephant for the Republican Party. Contrary to popular belief, Nast did not create Uncle Sam, Columbia, or the Democratic donkey, although he did popularize those symbols through his artwork. Nast was associated with the magazine Harper's Weekly from 1859 to 1860 and from 1862 until 1886.
