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's reindeer
In traditional festive legend, Santa Claus's reindeer pull a sleigh through the night sky to help Santa Claus deliver gifts to children on Christmas Eve. The commonly cited names of the eight reindeer are Dasher, Dancer, Prancer, Vixen, Comet, Cupid, Donner and Blitzen. They are based on those used in the 1823 poem "A Visit from St. Nicholas" (commonly called "The Night Before Christmas") by Clement Clarke Moore, arguably the basis of the reindeers' popularity.
