In American folklore, a Christmas elf is a diminutive creature (elf) that lives with Santa Claus in the North Pole and acts as his helper. Christmas elves are often depicted as green or red clad with large, pointy ears and pointy hats. Santa's elves are often said to make the toys in Santa's workshop and take care of his reindeer, among other tasks.
They were first introduced in literature by Louisa May Alcott in 1856. The Santa Claus character is much older, emerging in US folklore in the early 17th century from the historical figure St. Nicholas of Myra with attributes of various European Christmas traditions, especially from English Father Christmas and Dutch Sinterklaas. The association of Christmas presents with elves has precedents in the first half of the 19th century with the Tomte in Sweden and Nisse in Denmark, and St Nicholas himself is called an elf in A Visit from St. Nicholas (1823).
The Christmas elf appeared in literature as early as 1850 when Louisa May Alcott completed, but never published a book entitled Christmas Elves. The image of the elves in the workshop was popularised by Godey's Lady's Book, with a front cover illustration for its 1873 Christmas Issue showing Santa surrounded by toys and elves with the caption, "Here we have an idea of the preparations that are made to supply the young folks with toys at Christmas time." During this time Godey's was immensely influential to the birth of Christmas traditions, having shown the first widely circulated picture of a modern Christmas tree on the front cover of its 1850 Christmas issue. Additional recognition was given in Austin Thompson's 1876 work "The House of Santa Claus, a Christmas Fairy Show for Sunday Schools".
