Thomas Nast (; German: [nast]; September 26, 1840 December 7, 1902) was 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. He created a modern version of Santa Claus (based on the traditional German figures of Sankt Nikolaus and Weihnachtsmann) and the political symbol of the elephant for the Republican Party (GOP). Contrary to popular belief, Nast did not create Uncle Sam (the male personification of the United States Federal Government), Columbia (the female personification of American values), 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.



A cartoon is a type of illustration that is typically drawn, sometimes animated, in an unrealistic or semi-realistic style. The specific meaning has evolved over time, but the modern usage usually refers to either: an image or series of images intended for satire, caricature, or humor; or a motion picture that relies on a sequence of illustrations for its animation. Someone who creates cartoons in the first sense is called a cartoonist, and in the second sense they are usually called an animator.

The concept originated in the Middle Ages, and first described a preparatory drawing for a piece of art, such as a painting, fresco, tapestry, or stained glass window. In the 19th century, beginning in Punch magazine in 1843, cartoon came to refer – ironically at first – to humorous illustrations in magazines and newspapers. Then it also was used for political cartoons and comic strips. When the medium developed, in the early 20th century, it began to refer to animated films which resembled print cartoons.
