Patrick Courrielche
In 2015, Courrielche wrote a long form story "St. Nicholas: The Birth Of A Social Weapon" on the origin of Santa Claus and introduced the concept of a "social weapon" - a packaged idea, message, or product that is used by an individual or group to advance their cause. Courrielche argued that New York City elites crafted Santa Claus from St. Nicholas, a widely known patron saint, to stabilize a city plagued by annual misbehavior every December. Santa Claus was then used as a "social weapon" by merchants, craftsman, city rulers, parents, newspapers, and others to benefit their endeavors. The essay was added to the St. Nicholas Center's resource on the Origin of Santa Claus.
Santa Claus
Thomas Nast immortalized Santa Claus with an illustration for the 3 January 1863 issue of "Harper's Weekly". Santa was dressed in an American flag, and had a puppet with the name "Jeff" written on it, reflecting its Civil War context.
The story that Santa Claus lives at the North Pole may also have been a Nast creation. His Christmas image in the "Harper's" issue dated 29 December 1866 was a collage of engravings titled "Santa Claus and His Works", which included the caption "Santa Claussville, N.P." A color collection of Nast's pictures, published in 1869, had a poem also titled "Santa Claus and His Works" by George P. Webster, who wrote that Santa Claus's home was "near the North Pole, in the ice and snow". The tale had become well known by the 1870s. A boy from Colorado writing to the children's magazine "The Nursery" in late 1874 said, "If we did not live so very far from the North Pole, I should ask Santa Claus to bring me a donkey."
